3D Draw Shadows application is an easy-to-use, parametric CAD tool for everyday 3D modelling. Unlike most of other 3D tools, 3D Draw Shadows displays not only objects themselves, but also the shadows they cast. The parametric CAD features of 3D Draw Shadows allows you to compose scenes, populate them with objects, change object dimensions, location, orientation, colors, and reflectivities. After all these transformations, you can save scenes in (.sa1) files. 3D Draw Shadows is a stand-alone tool. It does not depend on any other applications or any third-party packages.
