NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. The connection to a geometry kernel allows the handling of IGES and STEP files. NETGEN contains modules for mesh optimization and hierarchical mesh refinement. Netgen 6.x supports scripting via a Python interface.
IFC++ is an open source C++ class model, as well as a reader and writer for IFC files in STEP format. Features include: Easy and efficient memory management using smart pointers. Parallel reader for very fast parsing on multi-core CPU's Retrieve ALL data from the IFC model, including property sets, material information etc. Additionally, there's a simple IFC viewer application, using Qt and OpenSceneGraph. It can be used as starting point for all kinds of applications around
