The TouchCAD modeling engine provides fast and precise push-pull free form 3D modeling, based on 3D-math curves. The toolbox includes many basic shapes such as lines, polygons, curves, rectangles, double lines, points, cubes, surfaces, tubes, T-tubes, spheres, rectangle to circle extrusions, and tools for extrusion, lofting, path extrudes, sweep/revolve, etc. The unique scale box feature allows mode-less editing with a wide range of features.
