From the developer:
The REVOLUTION4D plugin is a tool which can expand the modeling features of the Realsoft3D software, by integrating the functionalities of the OpenCASCADE geometric kernel.
This plugin is mostly intended as a complementary tool for the CHRONO plugin, because it allows the user to manage 3D models of CAD quality -this is especially useful for users which work with mechanism design etc.
