HeeksCAD

HeeksCAD is a free, open source, CAD application - Imports solid models from STEP and IGES files. Draws construction geometry and lines and arcs. Creates 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. Saves IGES, STEP and STL. Printer plot the 2D geometry or to HPGL. Imports and export dxf files; lines, arcs, ellipses, splines and polylines are supported. Uses the geometric constraints solver to create accurate drawings from rough sketches.
