Summary0029375: Data Exchange - Names of entities do not appear when the STEP file is imported in CATIA
DescriptionThe issue is explained here with sample workaround at: https://www.opencascade.com/content/exporting-list-named-points-step

Setting the names of shape's corresponding STEP entities (StepRepr_RepresentationItem) while exporting to STEP files does not make the name appear when STEP file is imported in CATIA. This is because CATIA extracts the names from geometric primitives contained within the entities.

A workaround is posted in the forum link pasted above. The workaround involves downcasting the StepRepr_RepresentationItem to its dynamic type and then setting the names of geometric entities contained within the StepShape_GeometricSet.

This solutions should be available in OCCT so that the workarounds can be avoided and the ease of usage of the library can be enhanced.
