Engineers, designers and companies in search of a free parametric 3D CAD tool for their models
About SolveSpace
SOLVESPACE is a free (GPLv3) parametric 3d CAD tool. Modeling 3d parts, drawing 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. Sketch sections using lines, rectangles, datum lines and points. Sketch circles, arcs of a circle, datum circles, cubic Bezier segments, C2 interpolating splines, and more.

FreeCAD
FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production ready drawings. FreeCAD is a multiplatfom (Windows, Mac and Linux), highly customizable and extensible software. It reads and writes to many open file formats such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE and many others, making it possible to seamlessly integrate it into your workflow. FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture. Whether you are a hobbyist, a programmer, an experienced CAD user, a student or a teacher, you will feel right at home with FreeCAD.
