I am using OCAF to export shapes to step file. All shapes and their sub shapes are attached with a name. I try to export all these information into the step file. But when I import the saved file, I find only the top-level shapes' name are available. I open the step file and find only the top-level shapes' name are stored and sub shapes' name are abandoned. I wonder know whether step support naming/coloring sub shapes. Does iges support naming/coloring sub shapes?
Thanks in advanced. Any suggestion is welcome.
