Detailed Description

Provides a tool to read STEP file and put it into DECAF document. Besides transfer of shapes (including assemblies) provided by STEPControl, supports also colors and part names.

This reader supports reading files with external references i.e. multifile reading It behaves as usual Reader (from STEPControl) for the main file (e.g. if it is single file) Results of reading other files can be accessed by name of the file or by iterating on a readers
