I have a CAD model designed in FreeCAD and need to export it to a STEP file (neutral CAD format) to be used in numerical anaysis software. I would like to assign names to selected surfaces in order to later define analysis boundary conditions on them. Is there a way to
- Define surface names directly in FreeCAD so that they are kept by the STEP export and seen by the analysis pre-processor after import, or
- Manually edit the STEP file and inject the names at approproiate places
Regarding the second option, I am able to identify the relevant surface and the definition looks like this
#885 = CYLINDRICAL_SURFACE('',#886,53.);
I tried adding a name between the apostrophes but this didn't seem to make any difference
#885 = CYLINDRICAL_SURFACE('mySurfaceName',#886,53.);
A link to a detailed description of the STEP format would be very useful too.
