SolveSpace is a parametric 2d/3d CAD program. Applications include:

* modeling 3d parts — draw with extrudes, revolves, helix creation, and Boolean (union / difference / intersection) operations; * modeling 2d parts — draw the part as a single section, and export DXF, PDF, SVG; use 3d assembly to verify fit; * 3d-printed parts — export the STL or other triangle mesh expected by most 3d printers; * preparing CAM data — export 2d vector art for a waterjet machine or laser cutter; or generate STEP or STL, for import into third-party CAM software for machining; * mechanism design — use the constraint solver to simulate planar or spatial linkages, with pin, ball, or slide joints; * plane and solid geometry — replace hand-solved trigonometry and spreadsheets with a live dimensioned drawing.
