LibreCAD - Open Source 2D-CAD

SOLVESPACE - parametric 2D/3D CAD

LibreCAD is a free Open Source CAD application for Windows, Apple and Linux. Support and documentation are free from our large, dedicated community of users, contributors and developers.

SOLVESPACE -- parametric 2D/3D CAD, is a free (GPLv3) parametric 3D CAD tool.

Applications include:

• modeling 3d parts — draw with extrudes, revolves, helixes 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
