This command line tool converts STEP CAD data into triangular meshes, and then writes the result into lightweight files for use in WebGL and other visualization applications.
The STEP reading and faceting is handled by ST-Developer libraries. This code traverses the resulting mesh data and writes STL or a simple webxml format. If you have a mesh format that you prefer, consider adding a writer for it and including it as a command line option.
The webxml format description and a javascript client for displaying it as WebGL can be found at:
This package contains a Visual Studio 2013 project file for building. When using with ST-Developer Personal Edition, set the platform to either "Release DLL" or "Debug DLL". There is also an NMAKE makefile called win32.mak which can be used for command line builds.
The package uses the ST-Developer libraries to read/write STEP files and mesh the CAD geometry. A downloadable version that is free for personal use can be found at:
