LiliCAD

From inspection to creation — precise measurement tools, 2D sketching, and parametric 3D modeling inside a focused dark interface.

Cross-platform, lightweight & modern

LiliCAD is a cross-platform desktop app with a modern dark interface tuned for clarity. 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 and markup tools

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 with 2D thickness overlay

Sectioning & Pinned Callouts

Adjust axis-aligned section planes with a slider, remesh the cap into a uniform thickness heatmap, and pin measurements or outlines so callouts stay put as you switch views.

3D thickness analysis

3D Thickness Computation

Reverse normals map global wall thickness as a color heatmap with live readouts and pins for critical areas.

2D sketching workspace

2D Sketching Workspace

Snap-aware lines, arcs, polylines, and Beziers on XY/YZ/ZX planes stay ready for downstream CAD work.

Parametric solid creation

Parametric Solid Creation

Extrude, revolve, and sweep sketches into solids, then combine them with manifold-powered boolean operations.
