DesignSpark Mechanical is a 3D modeling software reported to be easy to use so that all engineers will be able to create and share models.Designs can be linked directly to RS/Allied off-the-shelf components for automatic bill of materials generation, part numbers, and costs for included components.DesignSpark Mechanical can export to DXF, SketchUp, ECAD, OBJ, STEP, and STL formats. Since the software is free, designs can be shared in native electronic form for providing 3D models to your customers and sharing with other engineers and management involved with the project. Designs can be sent directly to rapid prototyping/3D printer devices for quick prototyping. »

CATIA (Computer Aided Three-dimensional Interactive Application) (in English usually pronounced /k?'ti?/) is a multi-platform CAD/CAM/CAE commercial software suite developed by the French company Dassault Systèmes. Written in the C++ programming language, CATIA is the cornerstone of the Dassault Systèmes product lifecycle management software suite.

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. »
