SolveSpace is a parametric 3D CAD program with extrude, revolve, union and difference functions. Save/Export as DXF, PDF, SVG, STL, STEP. Mesh generation expected by most 3d printers. Constraint solver point tracing for motion analysis.
Free • Open Source
What is SolveSpace?
SolveSpace is an Open Source 2D and 3D CAD (computer-aided design) program. It is a constraint-based parametric modeler with simple mechanical simulation capabilities. It is developed by Jonathan Westhues.
Modeling 3D parts – Draw with extrudes, revolves, and Boolean (union / difference) operations
Modeling 2D parts – Draw the part as a single section, and export as a DXF, PDF or SVG; use 3D assembly to verify fit
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
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
No need installation and you can edit measuremeant constraints fast

sgtdre It shows that it can open .step files and I have a few GrabCad files that I want to check out and see it I can at least save to other file formats, ;ie .dwg

SolveSpace is very easy and simple to use and very light. I also like FreeCAD as a good alternative except that it has a knack for being hard to use and for glitching. SolveSpace is not nearly as powerful, but rarely glitches and can do pretty much all of the basics. Can export to .step, .obj, .stl, .dwg, etc. Very solid. Very usable. I'm a big fan.
