LiliCAD
From inspection to creation — precise measurement tools, 2D sketching, and parametric 3D modeling. Explore, measure, sketch, and build in both dark and light themes.
DownloadCross-platform, lightweight & modern
LiliCAD is a cross-platform desktop app with a modern interface supporting light and dark modes. Measure with precision using point, point-to-point, edge, and tape tools with vertex snapping. Section models along standard axes and compute 3D/2D thickness with color-coded heatmaps. Sketch 2D profiles with lines, arcs, circles, and Bezier curves, then build parametric solids using extrude, revolve, and sweep operations. Combine shapes with boolean operations powered by the Manifold 3D engine.
Measurement & Markup Tools
Point, edge, and tape tools snap to vertices for precise distances, while anchored text markups capture quick context anywhere on the mesh.
Sectioning & Pinned Callouts
Adjust axis-aligned section planes with a slider and pin measurements or outlines so callouts stay put as you switch views.
3D Thickness Computation
Reverse normals map global wall thickness as a color heatmap with live readouts and pins for critical areas.
2D Section Thickness
Remesh any section cap into a uniform grid to show in-plane thickness as a color overlay with hover readouts.
Tight Fitting Bounding Box
A background worker samples ~200 orientations to deliver the tightest oriented box plus width/height/depth callouts.
2D Sketching Workspace
Snap-aware lines, arcs, polylines, and Beziers on XY/YZ/ZX planes stay ready for downstream CAD work.
Parametric Solid Creation
Extrude, revolve, and sweep sketches into solids, then combine them with manifold-powered boolean operations.
