ZW3D LITE is the world's most economical full mechanical CAD software to include unlimited use of all of the traditional design tools, including parametric part and assembly design, associative 2D drafting, 3D PMI (similar to "Model Based Definition"), 3D direct editing of imported data and much more. Not only can it directly read and edit 3D models from CATIA, NX, Creo, Inventor and Solidworks, but also import and export STEP, STL, IGES, Parasolid, DWG, DXF and SAT formats. ZW3D allows users to work with either solid, surface or wireframe in a single easy-to-use environment with modern ribbon-UI and context-help tools - already included in ZW3D LITE! Show More.
