User guide.

Assistant. On the Assistant tab, tick Enable LandForm Assistant to show the assistant and its workflow instruction cards while a tool runs, or clear it to hide them everywhere. Under Behavior, choose the Assistant persona (Classic or Lady), the card Color (LandForm, Random palette, Blue, Olive, Plum, Amber or Gray) and the Opacity of the cards, from 45% to 100%.

Closing the assistant with its own × button also turns this setting off.

Cursor. On the Cursor tab, pick Full screen length to stretch the pick crosshair across the whole Revit window, or Manual length and type its total span in pixels (24 to 2000). Tick Use LandForm theme color to follow the light or dark theme, or clear it and type a hex colour or press Pick to choose one; the swatch shows the result.

Element Info. On the Element Info tab, tick Show element info while hovering to get a small card with the category, type name, element ID and workset of the element under a resting cursor. It works in plans, sections, elevations and orthographic 3D views; clear the box to hide the card everywhere.

Colored Tabs. On the Colored Tabs tab, tick Enable Colored Tabs, then choose a style for Project tabs and for Family tabs: a top bar or a border in four weights, or Background Fill. Under Color by, choose Each view for a different colour per tab, Same view type to share a colour across all plans, all sections and so on, or Same opened model to colour every tab of one project or family alike.

Reset assignments forgets which colour each open tab was given so they are dealt out again from the palette.

Title filters (optional). Press Add under Title filters to create a rule, type the text or regular expression a tab title must match in Match, and set its Color by typing a hex value, pressing Pick or double-clicking the row. Clear On to pause a rule, or select it and press Remove.

An invalid regular expression falls back to plain text matching.

Ordered palette. Edit the colours the tabs cycle through: Add appends a colour, Pick (or a double-click) opens the colour picker for the selected row, Remove deletes it, Up and Down change the order, and Defaults restores the standard ten colours.

Save. Press Save. The Assistant, hover card and Colored Tabs settings take effect immediately; Cancel leaves everything as it was.

Read the status. The badge at the top tells you where the computer stands: LICENSED, LICENSE REQUIRED, LICENSE EXPIRED, LICENSE DISABLED, RE-VALIDATION NEEDED or, just after an activation, ACTIVATED. The card below says whether the tools are available and, for a licensed computer, whether all tools are included or some are greyed out on the ribbon.

A licensed computer also shows how it is licensed: an Autodesk App Store subscription verified for the Autodesk Account signed in to Revit, or a LandForm license valid through a given date.

Subscribe. When a license is required or has expired, the purchase card names the shop for the one-year subscription and the Buy on … button opens it in your browser. The App Store edition sends you to the LandForm listing on the Autodesk App Store, where the subscription is verified automatically with the Autodesk Account you use in Revit. The website edition sends you to landformautomation.com, and the license key arrives by email.

Email support opens a message to LandForm with the computer name already in the subject line.

Activate a key. Paste the key into the License key field and press Activate (or Enter). The window reports "Contacting the license service..." and then either the error the service returned or the new status.

Restart Revit. After a successful activation, a verified subscription or a successful Check again, the badge reads ACTIVATED and the window asks you to restart Revit. The LandForm ribbon is built when Revit starts, so the tools appear after the next start.

Check again. If the status says the license service could not be reached, press Check again in the footer; the window also re-checks on its own when the startup check did not get an answer. Press Close when you are done.

Load the surfaces. Start the tool with the surfaces selected, or choose Pick one surface or All visible floors and Toposolids in the dialog. LandForm reads the geometry and opens the studio over the Revit view, with the rest of the view ghosted around the terrain for context.

With several surfaces loaded they edit as one mesh: a stroke or grading design changes whichever surface lies under it.

Sculpt by hand. Choose Sculpt in the bottom action strip and drag upward on the terrain to raise it or downward to lower it. Open the brush settings next to it to set Brush radius (m) and the shape (Circle, Oval, Rectangle, Square); [ and ] resize the brush and Space rotates it by 15°.

Flatten pulls the ground under the brush to the picked level, and Smooth evens out a rough patch. The m box at the left of the strip is the brush grid spacing.

Add a pad. Choose Add pad, pick a Pad shape (closed polyline, circle, rectangle, square or a single spot level) and click it on the terrain, or use Pick from Revit to follow a model or detail line. Enter the Pad elevation (m), choose how the Surrounding terrain meets it (Cut / fill embankment, Smooth transition or Straight cut · vertical sides) and set the cut and fill slopes. Press Add pad to stage it.

Cutter opens the same tool already set to a straight cut, for a flat excavation with vertical sides.

Add a path. Choose Add path, click the route points and right-click to finish. Set the Centerline (polyline, smooth curve or tangent arcs), Path width (m), shoulders and Crossfall (%), then pick a Grade control: a fixed slope, an end elevation, follow the terrain, or a Design profile you edit in the profile window. Press Add path.

Turn on Auto-join intersecting paths to blend crossings and T-junctions into paths you have already drawn.

Hold a contour. Choose Add contour, draw the line, give it a Contour elevation (m) or click individual point labels to give points their own heights, set the Influence width each side (m) and press Add contour. The ground grades between the contour and the existing terrain across that width.

Check the design. Use the display toolbar along the top to switch on contours, the elevation heatmap, downhill flow arrows or slope grade arrows (amber below the minimum, red above the maximum you set). The Cut & fill card shows cut, fill and net volume for the current edits. Open Section cut and press Draw section line to cut through the terrain; 2D section shows the same cut at true scale.

Save to Revit. Press Save to Revit (Ctrl+Enter). Sculpting and small edits are written straight away, changing only the touched points. For larger edits a chooser opens with the recommended route first; see the section below. A progress bar runs while Revit works, then the studio closes and an Apply complete notice summarises what was written.

Prefer New Toposolid when you want a fresh element built from the preview and the source left untouched.

Pick the location. Click Move / Pick Location, then click the toposolid or floor where the mound centre should be. The toolbar reappears and the status line confirms the surface.

Choose the plan shape. Open Shape and pick a preset, or choose Custom and trace an outline you have already drawn as model lines or a filled region.

Press Space to rotate a non-circular shape in 15° steps.

Set the size. Enter Diameter, Height and Spacing. Long-press any of the three boxes and drag vertically to scrub the value while the preview follows.

Use a negative Height to make a depression.

Choose the profile. Open Profile and pick the section shape. Sphere gives a soft dome; a plateau profile keeps a flat top for seating or play equipment.

Preview. Press Preview and look at the point field on screen. Switch to a 3D view if you want to judge the height against nearby elements; the preview is redrawn when you change a value.

Refine with grips (optional). Turn on Grips to show the summit grips, then use + Grip, Set Height and Select Grips to raise or lower parts of the mound. Turn on Bezier Base to drag the base anchors and reshape the outline.

Apply. Press Apply. LandForm adds the shape points to the surface in one undoable step named "LF-Mound Factory: Apply".

Pick the surface. The pick starts as soon as the toolbar opens: click the toposolid or floor you want to shape. The status line changes from "Step 1" to "Step 2" and the surface boundary is highlighted.

If you shaped this surface with Smooth Mound before, the previous path and settings are restored from the surface and you can carry on editing them.

Draw the path. Click the stations of the crest line on the surface, one after another, then press Esc to finish. At least two stations are needed; the draft line appears after the second click.

To start the line again later, press the Draw path shortcut (Ctrl+Alt+D by default) and click a new set of stations.

Set station heights. Each station gets an adaptive point grip in the model with an elevation chip beside it. Select a station by clicking its grip, or step through them with Tab and Shift+Tab, then type its level in the Z box, nudge it with the arrows (0.10 m per step), or click the chip on screen and type the exact value.

Z is metres above the Project Base Point, so the numbers match Revit spot elevations.

Move, add or remove stations. Drag a grip with Revit's own Move tool to shift a station in plan or height; the preview follows. Press + and click the surface to insert a station on the nearest segment of the path, or − to remove the selected one (the path always keeps at least two).

Choose the section. Open Profile and pick Arc, Bezier, Half Sphere or Plateau. Press Edit to open the live section window, where you drag the curve or its grips to change the fullness, shoulder width or chamfer; the toolbar follows your changes.

Set the grid and the preview. Enter Spacing, the distance between the shape points that will be written (0.05 to 20 m). Under View, choose Points to see the point field or Isolines to see contours at the Contours interval you enter.

The preview redraws itself about a third of a second after every change; the status line and the "stations | points" counter tell you what it contains.

Run. Press Run (or Ctrl+Alt+Enter). LandForm generates the final point field at your spacing and rebuilds the surface in one undoable step named "LF-Smooth Mound: Apply Shape". When it finishes, the status line reports how many shape points were written and the button changes to Run Again, which starts a fresh surface pick.

Pick the surface. Revit asks you to select the floor or toposolid to shape as soon as the toolbar opens.

A surface that already carries an Auto Mound reloads its saved settings.

Pick the base outline. Revit then asks for the outline the mound rises from. Click a floor, toposolid, toposolid subdivision or filled region on the surface, and only the area inside its outline is shaped. Click the same surface again to mound all of it instead. Base then reads Whole surface. LandForm places the axis with five grips and draws the preview straight away.

To outline the base another way, change Base and the matching pick starts at once. With Picked edges, click model edges that go all the way round, then Finish. With Model lines, select model lines, detail lines or a filled region that form a closed outline, then Finish. With Drawn outline, click the corners on the surface, then click the first corner again or press Esc to close it. The outline is laid onto the surface and trimmed to its edge, and the axis and grips are worked out from it. The button beside Base picks the outline again. Auto Mound keeps an outline method for the next mound in the same Revit session. A new session always starts with the outline pick, so Auto Mound never reshapes a whole surface unless you click it.

Set the height. Type the summit height in Height, step it by 0.10 m with the arrows, or press - and + while the toolbar is open. The preview refreshes a moment after each change.

Shape the axis. Drag any grip in the model to move the axis or change its height there; the preview follows. Add grip and Remove grip change the number of grips and redistribute the arc evenly along the axis. An elongated surface keeps at least three grips; a circular one has a single centre grip.

Choose the section. Profile sets the cross-section from the axis down to the boundary: Arc, Bezier, Half Sphere (the default) or Plateau. Press Edit to adjust the curve in the live section window.

Invert for a depression (optional). Tick Invert to sink the shape below the surface by the same height. The grips flip through the surface and keep any manual edits you made.

Set the density and preview style. Spacing is the distance between the shape points LandForm will add. Display switches the preview between Isolines (drawn at 0.10 m intervals) and Points.

Run. Press Run. LandForm writes the mound in one undoable step named "LF-Auto Mound: Apply Shape" and reports how many shape points it added. The button then reads Run Again, which starts another surface pick. To add another mound to the same surface, choose or re-pick a Base instead.

Select the surfaces. Revit asks you to select touching floors or toposolids. Click each one and finish the selection. If fewer than two are picked the status line asks you to select again. LandForm estimates the combined outer boundary, places the axis with five grips and shows a point preview across every surface.

Set the height. Type the summit height in Height, or step it by 0.10 m with the arrows or the - and + keys. The preview refreshes a moment later.

Shape the axis. Drag the grips in the model to move the axis or change its height, or use Add grip and Remove grip to change how many there are. The arc is redistributed evenly each time.

Choose the section. Profile picks the cross-section from the axis to the boundary: Arc, Bezier, Half Sphere or Plateau. Edit opens the live section window.

Invert for a basin (optional). Tick Invert to sink the shape below the surfaces by the same height while keeping any grip edits.

Set the spacing. Spacing controls the point grid written to each surface. Composite Mound always previews points; there is no isoline display here.

Run. Press Run. LandForm creates the temporary mound, drapes each selected surface onto it, verifies the requested grid on every surface and deletes the temporary mound. The status line reports how many surfaces were draped and how many shape points were written.

Place the first grip. Click a point on the toposolid or floor where the first peak should be. The toolbar opens with Station 1 / 1, the preview appears around the point, and Revit keeps asking for more points.

Add more grips. Keep clicking the same surface to add stations; each new grip takes the height, diameter and shape of the selected one and becomes the selection. Press Esc when you have placed enough.

Press + at any time to pick more stations, and − to remove the selected one (the last remaining grip cannot be removed).

Set the selected grip. Click a grip in the model to select it, then type its peak level in Z (metres above the Project Base Point) or step it with the arrows, - and +. Set the footprint with D (arrows, [ and ]). Choose Oval or Rectangle under Shape to unlock D2, the second diameter, and Angle, the rotation in 5° steps.

A Z below the surface pulls the ground down instead of raising it, which makes a hollow or pond. Each grip also shows an elevation chip in the view; click the chip to type the level in place.

Move grips in the model. Drag a grip with Revit's Move tool, or select it and move it, to shift the station. Its base is re-projected onto the surface and the peak keeps its height above the ground, so the preview follows.

Choose the section and the grid. Pick Arc, Bezier, Half Sphere or Plateau under Profile, or press Edit to shape the section in the live profile window. Enter Spacing, the distance between the points LandForm will write (minimum 0.10 m).

Tune the preview. Switch Preview between Points, Contours and Points + Contours, and set the Contour interval. Leave Keep boundary elevations on to lock the outer edge of the surface, and turn on Connect grips to blend all stations into one smooth ridge along the order you placed them.

Apply. Press Apply. LandForm builds the full-resolution point field and edits the surface in one undoable step named "LF-Point Grip Mound: Apply Shape". The status line reports how many points were written and the toolbar stays open, so you can keep adjusting and apply again; press the X to finish.

Pick the surface. The status line reads "Step 1" as soon as the toolbar opens: click the floor or toposolid in the view.

Pick the contour lines. The prompt moves to "Step 2". Click each elevated model line; every click adds that line plus any lines joined to it, and the preview grid redraws with the new line included. Press Esc when all the lines are in.

A line that is not level, or one you have already added, is skipped with a note in the status line.

Tune the blend. Change Spacing, Falloff, Profile and Grid; the preview refreshes as you type. Profile sets the shape between two contour elevations: Straight for a direct match, Arc, Cubic (the default S-curve) or Bulge. Grid lays the points out Square or Triangular.

Check the preview. The point count sits at the right of the status line, and a ! appears when the field is large enough to slow Revit. Dense previews are drawn at a coarser spacing to stay responsive; the status line says so, and Apply still uses the spacing you entered.

Apply. Press Apply when the grid follows the lines. LandForm regenerates the field at your spacing, writes it in one undoable step named "LF-Attract From Lines: Apply Shape", reports the number of points and closes the toolbar.

Pick the surface. Revit asks for a floor or toposolid as soon as the toolbar opens. In Smooth and Rebuild modes the preview appears straight away; a surface that already carries Relax Surface settings reloads them, guides included.

Choose the mode. Smooth relaxes the current interior points. Rebuild discards them and recreates the interior from the boundary alone. Guides interpolates the surface through guide contours you draw.

In Smooth mode, set Passes. Each pass flattens interior detail a little further; the arrows step by 10 and the range is 1 to 1000.

In Guides mode, draw guides. Press Guide +, click at least two stations across the surface and press Esc to finish. Repeat for each contour. Or press Trace to recreate the surface's existing contours as guide splines with a few grips each, replacing the current guides.

Edit the guide stations. Select a station and type its height in Z or step it by 0.10 m with the arrows. Drag a station's adaptive grip in the model to move it; the preview follows. + inserts a station on the nearest guide segment, - removes the selected one (a guide left with fewer than two stations disappears), and Guide - removes the selected station's whole guide.

Set spacing and placement. Spacing sets the distance between the new interior points. Points chooses Grid, which writes evenly spaced points, Isolines, which writes points only along the relaxed surface's contours at the Contours interval, or Delaunay, which keeps only the points the relaxed shape needs within Tol (metres, 0.05 by default) and adds evenly spaced points up to Max edge (metres, 2 by default), so the surface comes out light with even triangles that are never thinner than 20°. Tol and Max edge only apply to Delaunay; leave Max edge empty for no size limit. View switches the preview between Points and Isolines.

Run. Press Run when the preview looks right. LandForm writes the relaxed interior in one undoable step named "LF-Relax Surface: Apply Shape" and reports how many shape points it added. The button then reads Run Again, which starts a new surface pick.

Toggle visibility. Choose Utils › Adaptive Points. If the category is hidden anywhere in the view or its template, LandForm turns it on; only when it is fully visible does it turn it off. A message confirms "Adaptive Points are ON" or "OFF" and names the view or view template that was changed.

When the view uses a view template, the template is updated and the view's own setting follows where Revit allows it, so every view on that template shows the grips.

Finish your mounds. Shape the terrain with the mound tools. Mound Factory, Smooth Mound, Auto Mound and Composite Mound switch the category on themselves when they start; Point Grip and Relax Surface warn you if it is hidden.

Clean up. Choose Utils › Cleanup Adaptive Points. LandForm searches the whole document for handles tagged by the mound tools and asks you to confirm the number it will delete. Say Yes and a message reports how many were removed.

Open the view to clean up. Any plan, section, elevation or 3D view will do.

Choose Visibility › Folding/Split Lines. If any of the four subcategories is showing, all four are hidden: Floors › Folding Lines, Floors › Split Lines, Toposolids › Folding Lines and Toposolids › Split Lines. A message confirms they are OFF and names the view or template that changed.

Choose it again to bring them back. Once all four are hidden the same command shows them again.

Open the view to grade. A section or elevation is the usual case; an orthographic 3D view works too, measured from its nearest element.

Choose Visibility › Depth Fade. A floating bar opens over the view.

Set the bands. Type how many depth bands the view is cut into, from 2 to 10 (5 by default). The nearest band is always black; the farthest takes the far shade; the bands between step evenly from one to the other.

Choose the far shade. Mid grey (128) keeps the background firmly part of the drawing, Light grey (170) is the default, Lighter (200) is a wash, Lightest (225) is barely there.

Set the depth. With Auto ticked the farthest element in the view (inside the far clip when it is on) gets the farthest band. Untick it to type the depth in metres at which the farthest band starts: everything at that depth or beyond takes the far shade, which keeps the same look across several sections of one site.

Tick Halftone or Thin lines if you want them. Both apply to every band behind the nearest one: Halftone blends the lines half-way to the paper on top of the grey, Thin lines draws them with line weight 1.

Apply. The bar reports how many elements were graded, over what depth and to which grey. Apply again whenever the model or the view changes; elements that have left the view are cleared.

Reset to put the view back. Reset removes exactly the overrides Depth Fade set in this view and nothing else.

Choose the kerb type. Open Kerb type and pick the railing type that models your kerb. The Base and Side boxes reload the offsets you last used with that type.

Set the offsets. Base lifts the kerb above the level it is created on; Side shifts it sideways from the edge it follows. Leave both at 0 to sit the kerb exactly on the edge.

The units follow the project's length unit, so a project in millimetres shows Millimeters beside the boxes.

Choose the placement. Set Placement to Selected edge to run the kerb along just the edge you click, or Entire boundary to follow the whole closed loop that edge belongs to.

The status line changes to match: "Pick the edge to use" or "Pick an edge on the boundary".

Pick from a link if needed. Tick Link to pick elements in a linked model instead of this one. Revit picks a link by element rather than by edge, so the kerb follows the boundary edge nearest your click; the hover highlight shows which edge that will be before you click.

Click the edge. Hover the edge until it highlights, then click. The kerb is created immediately in one undo step named "LF-Kerb: Create Kerb", and the toolbar is ready for the next edge.

If the status line says "Could not use the selected edge", the click did not land on a boundary edge of the upper surface of a supported element.

Reverse if needed. Press Reverse to flip the direction of the kerb you just created, so an asymmetric profile faces the other way. This writes one undo step named "LF-Kerb: Reverse Kerb".

Pause and resume. Press Esc to pause picking; the cursor is freed while the toolbar stays open and the status line reads "Paused - press Run Again or change an option to pick again". Press Run Again, or change the kerb type, an offset, the placement or Link, to pick again. Only the close button ends the tool.

Set the size range. Type Size min and max in metres (0.6 m and 1.8 m by default) and press Enter or Tab. The readout beside the controls shows the resolved length × width × height of the current shape, and the Shape code identifies that random form.

Choose the detail. Pick Facets from 8 to 20; more facets give more, smaller planar faces. Set Irregular from 0 for a regular form to 1 for a strongly fractured outline; 0.55 is the default.

Shuffle the form. Press Randomize for another shape inside the same size range. The Shape code and the size readout update each time; repeat until you like the proportions.

Place the boulder. Press Run, then click the placement point in the view. The status line reads "Pick the placement point in Revit..." while it waits; in a view with no work plane, click a point on a model surface instead.

LandForm writes the family file, loads it into the project and places one instance at the point you clicked.

Keep placing. The status line confirms "Created and placed LF-Boulder-… A new random boulder is ready for the next placement." Press Run again for the next boulder, changing the size range or detail between placements if you like. Close the toolbar with the × when you are done.

Select the boulder. Select a LandForm boulder before starting the tool, or start the tool and click one when the prompt says "Select a boulder created by LandForm Boulder Creator".

If several elements are selected, the first LandForm boulder among them is used.

Read the stored settings. The toolbar opens with the boulder's Size min, max, Facets, Irregular and Shape code. The selected instance is hidden in the active view and a grey preview of its current form is drawn in its place; the status line reads "Editing LF-Boulder-…".

Adjust the size or detail. Change any value and press Enter, or move to the next box. The preview is redrawn at the instance location after each change.

Try another form. Press Randomize to preview a different faceted shape while keeping the size controls. The status line reminds you that nothing is saved until you press Run.

Update the family. Press Run. LandForm regenerates the family file, reloads it over the existing family and redraws the preview; the status line confirms "… was regenerated and reloaded. Existing instances kept their locations."

Close the editor. Press the ×. The preview is cleared and the hidden instance is shown again in the view.

Pick the surface. In the Surface group, click Pick and select the host toposolid. Its name appears next to the button.

Sketch the centerline. In the Points group, click Draw and click the path points on the surface; press Esc when the route is complete. Or click Pick Lines and select a connected chain of lines, arcs or splines you have already drawn.

In the Centerline group, choose Spline for a smooth curve through the points, or Tangent-arc for straight legs joined by arcs of the Radius you enter, like a road alignment.

Adjust the route on screen. Editing starts as soon as the sketch is finished: drag a grip to move a point, click a + marker between two grips to insert a point there, or Ctrl+click a grip to remove it. Press Esc to stop; Edit, Add and Delete re-enter the same modes later.

Set the path section. In the Path group, enter Width (m), turn on Variable and enter End (m) for a tapering path, add a Shoulder (m) if you need a verge strip, and set Detail (m), the spacing between the stations LandForm grades.

Smaller detail follows curves and terrain more closely but takes longer to generate.

Choose how the path is graded. In the Grade group pick one of three modes. Follow surface drapes the path over the existing ground and lifts it by Lift (m). Fixed slope regrades the path at Slope % from the end you choose with Start, raised or lowered by Start offset (m), with Crossfall % across the path and Cut H:V and Fill H:V for the embankments. Design profile lets you drag the design level on the profile panel; Grips at stations gives you one grip per station to work with.

Add edges, stations and output type. Turn on Railings and choose a railing type to line both edges. Turn on Stations to see chainage ticks (0+000) at the Interval (m) you set, and Annotate to place those ticks and labels as detail lines and text when you run. Under Create as, choose Subdivision to keep the path as a sub-division of the host, or Toposolid to build a separate toposolid of the selected type.

Check the profile and section (optional). Turn on Profile to see existing ground in green and the design level in blue along the path. Turn on Section to see the cross-section at any station; drag its grips to shape a crown, swale or rounded verge. Both panels can be made Taller or Floated into their own window.

Run. Press Run. LandForm grades the path, blends the batters into the terrain and reports the result in the status line. Press Undo to remove the path and restore the surface, or Clear to discard the sketch and start again.

Pick the walls. Press Pick Walls, click the walls in the 3D view and click Finish. The preview is built straight away and the status line reports how many steps were fitted.

Walls selected before you opened the tool are used as soon as it starts.

Read the preview. Blue lines are the wall above grade. Amber outlines with diagonal hatching are the buried part. The magenta line is the low grade, and the large red arrows point towards the retained, uphill side. The Retained value on the right is the biggest grade difference across the run.

Set the visible height and embed depth. Type Visible height and Embed depth in metres. The preview refreshes about a quarter of a second after you stop typing.

Set the step rise. Type Step rise. The ground heights sampled every 0.5 m along the wall are rounded to this value, and a new step starts wherever the rounded height changes on either side, so a smaller rise gives more, shorter steps.

Snap the elevations (optional). Type an Elevation snap such as 0.05 to round every step's top and bottom to a multiple of that value, so copings and courses land on round numbers. Leave it at 0 for exact grades.

Refresh if needed. Press Update Preview to resample after you change the terrain or the view, or whenever you want to be sure the preview matches the toolbar.

Build the steps. Press Build Steps. LandForm recalculates from the values on the toolbar, replaces each picked wall with its stepped segments in one transaction named "LF-Grade Walls", and selects the new walls. The status line reports "N stepped wall segments created in one transaction."

Pick the walls. Walls selected before you started are picked up straight away. Otherwise press Pick Walls, click one wall of the run and click Finish; with Joins ticked the walls joined to its ends follow round the corners. The status line reports the number of walls and the run length, and notes any curved walls that will be shaped by an LF void cutter.

Drag the grips on screen. In a 3D view, an elevation or a section, drag the blue grips to move the top and the amber grips to move the bottom. Dragged elevations round to the Snap value in millimetres (10 mm by default; 0 turns snapping off). Click an elevation chip on screen to type its value exactly.

Or edit in the strip. The strip under the toolbar is the run unfolded, and works in any view: drag a grip up or down, slide a handle along the run by its triangle, double-click to add a handle, Ctrl+click or Delete to remove one. A ghost line shows the walls as they stand in the model, with the ground on the high and low side drawn beside it.

Keyboard: Left and Right select a handle, Up and Down nudge its top by the snap step, Shift+Up/Down nudge the bottom.

Add handles where you need them. Press + and click along the walls, at an edge or in the middle; press Esc when done. Step through the handles with the ‹ and › buttons, then type Top and Bottom in metres above the project base point and press Enter. The − button removes the selected handle; the two end handles always stay.

Set a slope. Type a Slope in percent (2.5) or as a ratio (1:20) and press Enter; a negative value falls along the run. The list beside it says what the slope sets: Top, next or Bottom, next from the selected handle to the following one, or Top, run and Bottom, run for one even slope over the whole run from the first handle. The box always shows the current slope of that span.

Choose straight or smooth. Tick Smooth for a curve through the handles that never overshoots them, or leave it off for straight lines from handle to handle.

Fit to Grade (optional). Open the gear beside Fit to Grade and choose Faces (Top faces of the ground, or Bottom faces of a slab, ramp or deck overhead), Fit (Top and bottom, Top only or Bottom only) and the Top offset and Bottom offset in metres. Press Fit to Grade: the top lands on the high side of the face plus the top offset, the bottom on the low side plus the bottom offset, with handles only where the face bends. The status line reports the face range that was read; Undo brings the previous shape back.

Apply. Press Apply. Only the walls whose shape changed are written, all in one undo step named "LF-Wall Shaper: Shape Walls", and the status line confirms how many walls were shaped. Wall Shaper stays open for more edits; the right of the status line shows Not applied while the shape on screen differs from the model.

Choose what to build. Under BUILD AS, pick Stair, Floor or Toposolid, then choose the type in the list beside it; the list switches between stair types and tread types to match.

Choose the host level and railing. Under HOST, pick the Level the flight is measured from; the flight is expressed as offsets from it, so the ends need no level of their own. Set Railing to None to remove the railings Revit adds to every stair, or pick a railing type. Railings apply to the Stair output only.

Choose the path source. Under PATH, pick Edge to run off a slab edge (arc edges stay curved), Lines to chain model or detail lines, Draw to click the line in the view, or Circular for concentric steps around a centre.

For Lines, Draw and Circular, Raise lifts or drops the guide in metres and Other side swaps the side the steps fall away to, because a line cannot tell which side is open air. Circular also takes Rad (0 reads the radius from the point you pick) and Sweep in degrees; negative sweeps clockwise and 360 makes a full ring.

Choose how the rise is measured. Under MODE, Manual takes a typed Height and runs Down from the picked line (hanging the flight below a terrace edge) or Up away from it. Auto, available for the Edge path only, measures the rise and the run from two slab edges, so you only type the number of Steps.

Proportion the steps. Under STEP, type the target Riser, the Min and Max riser you will accept and the Tread depth. In Manual mode the height is divided into equal risers as close to the target as the limits allow; in Auto mode the step count wins and the limits only warn.

Set the run. Under RUN, choose Across so the guide is the head of the stair and the steps run out from it, or Along so the guide becomes the walking line with the risers square across it, which turns an arc into a curved or spiral flight. Type Width: running Across, 0 takes the full length of the picked edge; running Along, type the width you want. Use Left, Center or Right to sit a narrower flight against an end of the edge, Flip to swap which end Left and Right mean, and End riser to finish on a riser face instead of a tread.

Pick the guide; this builds the flight. Press the green button, whose label follows the path source: Pick Edge, Pick 2 Edges (Auto: top edge then bottom edge), Pick Lines then Finish, Draw Line then Esc, or Pick Centre then the start of the sweep. The flight is solved and built immediately, and the status line reports the treads and risers, for example "9 treads and 10 risers, each 150 mm."

The right of the status line shows the guide and its length, the total Rise, the solved risers and tread in millimetres, and 2R+G, which turns red outside the 550 to 700 mm comfort range.

Adjust and rebuild. Change any setting and the preview redraws on the same guide: blue treads, magenta risers and the amber guide line. Press Rebuild to replace the previous flight with the new one, so nothing stacks up and a single Undo returns to the start. Press Reset to forget the guide and start a new flight elsewhere.

Select the source linework. Select the lines or the filled region in Revit, then press Refresh Selection. The status bar reports how many pattern sources are selected and the selection is highlighted on screen.

You can also select before opening the toolbar; the selection is read when the toolbar appears.

Name the pattern. Type a new name in Name, or pick an existing pattern from the list to redefine it. The list only shows patterns of the current Type.

Choose the type and scale. Set Type to Model or Drafting. Scale multiplies the drawn tile size; 1.0 keeps the size you drew. Drafting patterns are also divided by the active view scale, so open the view whose scale you document at.

Tick the extras you want. Region type duplicates a filled-region type named after the pattern with the new pattern as its foreground. Assign surface asks you to pick a floor or toposolid afterwards and sets the pattern as the Surface Foreground pattern of its type's material. Keep High resolution on so angled and curved linework keeps its angles.

Press Run and mark the tile. Click Run. Revit asks for the bottom-left corner of one repeating tile, then for the top-right corner; a rectangle follows the cursor so you can see the repeat area. Everything inside that rectangle becomes one repeat of the pattern.

Pick the surface (if asked). With Assign surface ticked, Step 3 asks for the floor or toposolid that should receive the pattern. Press Esc to skip the assignment and keep the pattern.

Export a PAT file (optional). Press Export PAT and choose a folder. With linework selected you mark the tile again and the file is built from it; with nothing selected, the pattern named in Name is read from the project and exported as it is. Units follow the mm / inch box.

Pick the surface. Press Pick Surface and click a floor or toposolid. The surface's native pattern is hidden in the active view and a live preview of the modelled lines is drawn in its place. Nothing is created yet.

The status line names the pattern and counts the lines, and warns when the pattern is heavy enough to make panning and zooming slow.

Turn the pattern (optional). Type an angle in Rotate, or press and drag on the box to nudge it. The preview redraws as soon as the value settles.

Line it up with an edge (optional). Press Align to Edge and click a straight edge, such as a slab edge, kerb or wall. The pattern turns to match it and starts on that edge instead of the project origin; the solved angle appears in Rotate. Clear drops the alignment again.

Decide where the native pattern is hidden. Leave Hide pattern in all views clear to hide it only in the view you apply from, or tick it to hide it in every plan, section, elevation and 3D view.

Apply. Press Apply and choose Only the selected surface or All visible instances of this type. When a single surface would get more than 10,000 lines, LandForm asks you to confirm that modelled geometry is really needed. A progress bar runs while the pattern is repeated, clipped and draped; Cancel stops it.

Keep working. Edit the host, its type, its material or the fill pattern as usual. While Auto Update is on, the overlay rebuilds itself. Press Discard at any point before Apply to drop the preview and bring the native pattern back.

Pick the host. Start the tool and click the Floor or Toposolid to pattern. The window opens on the Host tab and draws a first preview over the host.

Choose the bond. Open Pattern type and pick a layout: Stack bond, Running bond, Random stagger, Herringbone, Triangle, Crazy paving, Pentagonal rosette, Hexagon, Octagon and square, Diamond, Basket weave or Selected host pattern. A hint under the list explains how the chosen layout uses the cell size.

Herringbone adds a Herringbone angle field. Selected host pattern repeats the host's own Surface Foreground pattern instead of a generated bond.

Size the units. In the strip under the tabs, set Width (mm), Height (mm) and Joint (mm). Hover a field to get a slider, or type an exact value. Change Seed to reshuffle the colours and stagger without changing anything else.

Orient the pattern. Under Orientation, set Rotation (deg), or click Align to edge and pick a straight edge in the model so the courses run parallel to it. Use Pattern offset X and Pattern offset Y to slide the grid so a joint lands where you want it.

Build the palette. Open the Materials tab. Under Use, choose New Revit materials to define colours yourself, or Existing Revit materials to pick materials already in the project. Set Palette size, pick a Colour range to recolour the swatches, then set each colour's share under Distribution (%) until the total line reads "Total: 100%".

With new materials, click a swatch to change its colour and type a unique material name beside it.

Check the preview. Choose how the host is drawn under Host display in active view, tick Project preview to host surface if the host is shaped, and click Report to see areas and shares per colour.

Choose the output. Under Create as, pick JPEG, Placed PNG, 3D Coloured Mesh, Floors or Toposolids. For Floors and Toposolids, choose the Base type and check Warn above (cells).

Save the mix (optional). Type a name in the Mix name box and click Save to keep every setting in the project for the next host.

Create. Click the action button at the bottom right. Its label follows the output: Export JPEG, Place PNG, Create 3D Mesh, Create Floors or Create Toposolids. Progress shows beside the buttons, and the window stays open for another variation.

Pick the host. Start the tool and click the Floor or Toposolid. The window opens snapped beside the Revit view on the Dissolve tab, and a first preview is drawn over the host.

Choose the influence. Under Influence source, click Radial point for a dissolve around a centre, Perfect circle for paving set in concentric rings, or Selected path for a dissolve that follows lines.

For a centre, click Pick centre and click in the view; keep clicking to compare positions, then press Esc to keep the last one. Host centre puts it back in the middle of the host, and Centre X offset and Centre Y offset fine-tune it. For paths, click Pick paths, select one or more lines and click Finish. The status line confirms how many paths and curves are linked.

Arrange the units along the guide. With Selected path or Perfect circle, choose a Path arrangement. Influence only keeps a straight grid, Follow tangent turns each unit to the guide, Array along curve lays rows of units along it, and Follow curve + auto-cut bends the units to the curve and trims them where rows collide or meet the host edge. For rows along a path, set Pattern start offset and Row offset to place the first unit.

Shape the dissolve. Pick a Dissolve preset, then set Fade radius (how far the effect reaches), End size (%) and End density (%) (how small and how sparse the units are at that distance). Min cut size (%) drops slivers left by trimming.

For a centre-based dissolve you can also drag the grips in the view: the centre dot moves the influence (it snaps to the host centre), the cyan square changes the radius and the amber grip rotates the pattern. With paths, each path has its own radius and start grips. Release to refresh; Esc cancels a drag.

Set the colour transition. Under Colour mode, Fade blend swaps a growing share of units to the Fade target colour, up to the Colour fade (%) you set, in the Fade direction you choose. Divide into parts paints hard-edged colour bands instead, by Number of parts or Band distance.

Pick the pattern and unit size. On the Host tab, choose the Pattern type and Orientation, and set Width (mm), Height (mm), Joint (mm) and Seed in the strip under the tabs.

Build the palette and choose the output. On the Materials tab, set the colours or project materials and their Distribution (%), then choose Create as: JPEG, Placed PNG, 3D Coloured Mesh, Floors or Toposolids.

Create. Click the action button at the bottom right; its label follows the output (for example Create 3D Mesh). The window stays open, so you can save the mix and try another variation.
