Heeks CAD

HeeksCAD is a free and easy-to-use, open-source, CAD application—that imports solid models from STEP and IGES files. Draw construction geometry and lines and arcs. Create new primitive solids, or make solids by extruding a sketch or by making a lofted solid between sketches. Modify solids using blending, or boolean operations. Save IGES, STEP, and STL. The printer plots the 2D geometry to HPGL. Import and export dxf files; lines, arcs, ellipses, splines, and polylines are supported. Use the geometric constraints solver to create accurate drawings from rough sketches.
