Surfaces Toolbar
The Surface toolbar builds, cuts, combines and repairs triangulated surfaces and solids. Open it from its tab on the right edge of the window.
The controls
| Control | What it does | Other ways to use it | Guide |
|---|---|---|---|
| Triangulate | Builds a surface from visible points, lines and holes | Select a polygon first to clip to it | Triangulate |
| Surface Intersection | Draws the line where two surfaces cross | Pick each surface in 3D | Surface Intersection |
| Solid Boolean | Union, intersect or subtract two closed solids | Normals button fixes an input | Solid Boolean |
| Trimesh Boolean | Splits two surfaces and keeps the pieces you choose | Quick Boolean tab; Reclassify | Trimesh Boolean |
| Extrude KAD to Solid | Pushes a closed polygon into a solid | Select the polygon first | Extrude KAD to Solid |
| Contour Surface | Contour lines at a set interval | Custom start for bench RLs | Contour Surface |
| Clean Mesh | Finds and repairs mesh faults | Right-click a surface → Clean | Clean Mesh |
| Clip Surface | Cuts a surface or solid with a polygon | Batch tab for many cutters | Clip Surface |
| Solid Horizon Slice | Cuts a solid into horizontal bands | By count for equal bands | Solid Horizon Slice |

Working with one surface
Right-click a surface on the canvas — or choose Properties from its menu in the tree — to open its properties. There you set the Transparency, Color Gradient and elevation limits, see its area and volume, and reach Check, Clean and Smoothing.
The tree’s surface menu adds Convert to… (faces, edges or points as KAD), Footprint…, Normals… and Statistics. See Importing Surfaces and Surface Gradients.
