Section Cut
Slice any vertical plane through your 3D design to reveal grade changes, construction depths, and underground soil layers.
A section cut defines a vertical plane through the 3D scene using a two-point cut line you draw on a top-down map. The camera then looks straight into that plane, showing every element — terrain, planting, structures, and underground soil strata — in clean architectural cross-section. Use section cuts to communicate slope transitions, retaining wall heights, pond depths, or subsurface construction details to clients and contractors. Section cut controls are available exclusively in the Technical render style.
Draw the cut line
Click two points on the canvas to define the cut line. The cut plane is a vertical plane perpendicular to the canvas through that line. The 3D view immediately updates to show everything in front of the cut plane; geometry behind it is hidden.
Adjust cut elevation offset
Select the section cut entity and open the Inspector panel. Use the Elevation Offset control to shift the cut plane up or down relative to ground level. This lets you cut through specific layers or height levels.
Draw the cut line on the minimap
Click two points on the minimap to define where the vertical plane slices through the scene. The line can run at any angle — diagonal, perpendicular, or parallel to the site boundary. Everything in front of the plane stays visible in the 3D view; geometry behind it is clipped away so the cross-section reads clearly.
Choose the view side
After drawing, click Flip View Side to choose which side of the cut line the camera looks from. Pick the side that reveals the most important grade change or construction detail. The minimap shows an arrow indicating the current view direction.
Adjust the view depth
Use the View Depth slider to control how far behind the cut plane geometry remains visible. A shallow depth gives a clean, diagrammatic section with only the cut face shown. A deeper value lets you keep background planting or structures visible for context.
Show underground soil layers
Enable Show Soil Layers to render the underground strata as banded layers below the cut surface. The layer stack — including each layer's material, color, and depth — is defined in the project's soil profile in the Terrain module. Bezier boundary curves between layers can be dragged in the section boundary editor to adjust where each stratum appears along the cut.
Enter and exit the section view
Click View Section to switch the 3D camera to a straight-on orthographic view of the cross-section. Use this view to inspect grade relationships and structure heights before exporting. Click Exit Section View at any time to return to the normal perspective camera — the cut line is preserved.
Export the section as a deliverable
With the section view active, use High-Quality Capture or the standard screenshot tool to export the cross-section as an image. For PDF deliverables, add the section view as a slide in the Slideshow module so it exports alongside plans and elevations.
Remove Section Line permanently deletes the active cut line and any boundary edits you have made to the soil layers — this action cannot be undone from the panel. If you only need to step away temporarily, use Exit Section View instead, which keeps the cut line intact.
Place the cut line perpendicular to a slope or retaining wall to get the most informative cross-section. Angling the line along a gentle gradient rather than crossing it head-on will compress the grade change and make it harder to read.
You can save multiple named section lines in a project and switch the active one from the style panel. This lets you prepare A-A and B-B sections in advance and activate them individually for capture without redrawing the cut each time.
Frequently Asked Questions
I can't find the section cut controls.
Section cut is only available in the Technical render style. Open the style panel from the top bar, switch to Technical, and the Add Section Line option will appear at the bottom of the panel.
The section is facing the wrong direction.
Click Flip View Side in the style panel to look from the opposite side of the cut line. If the wrong features are showing behind the plane, lower the View Depth slider so only the slice face is visible.
Soil layers are not appearing in my section.
Make sure Show Soil Layers is enabled for the active section. The layers themselves — materials, colors, and depths — are configured in the project's soil profile in the Terrain module. If no soil profile has been set up, the underground area will appear empty.
Can I have more than one section cut in a project?
Yes. Click Add Section Line to create additional cuts. Each is stored separately and can be activated individually from the section cut area of the style panel. Only the active section affects the 3D view at any one time.
Can I edit the soil layer boundaries after the section is created?
Yes. When Show Soil Layers is on, the section boundary editor displays cubic bezier curves separating each stratum. You can drag the control points directly in the section view to reshape where a boundary sits along the cut — useful for showing an irregular hardpan or clay layer.
Proč se stěny a konstrukce v místě, kde jimi prochází řezná rovina, zobrazují jako otevřený obrys místo plné výplně?
Odpovídá to standardní architektonické kresebné konvenci: řez stěnou nebo konstrukcí se kreslí jako otevřený řez pláštěm, nikoli jako plný blok. Pouze terén — půdní profil, který nastavujete v modulu Terén — se vykresluje jako vyplněný průřez, protože plná výplň materiálu tam nese skutečnou informaci (která vrstva půdy se nachází v dané hloubce). Konstrukce zůstávají záměrně otevřené.
Proč změna slunce, počasí nebo ročního období neovlivní můj pohled na řez?
Section Cut (Řez) se vykresluje ve vyhrazeném technickém stylu (Technical), který záměrně ignoruje osvětlení podle denní doby, počasí i sezónní stav vegetace, takže průřez vždy vypadá stejně čistě a neutrálně bez ohledu na to, kdy byl pořízen. Pokud potřebujete fotorealistický render reagující na slunce a roční období, přepněte na styl Photoreal (Fotorealistický) — ovládací prvky řezu tam nejsou dostupné.
