Find faces based on their names in existing .step file

[gohu41]

Hello,

I am trying to open a .step file, find faces based on their name, find the edges of these faces, and name those edges.
I have worked out how to load the file, list the faces and list the edges of a face, but I haven't managed to find the name of those faces.

I have attached two simple cad files : one with 5 named faces, and the result I want to achieve (same cad but with the edges named).

Any help/hint is appreciated.

Thanks,

Hugo

This in-progress PR may be of interest to you. It works with assemblies, but it can import face names.

Hi Jeremy,
Do you mean there is no way to import face names with the current code in master ? And that feature will be available when the merge request is complete ?
Thanks

Correct. I do not believe that there is any way to get face names, colors and layers currently without dropping back to the OCP layer and writing lower level code yourself.

Thanks, I will either wait for the merge request to complete or try to work something out with OCP.
Is there a way to name edges in a way that is persistent when the shape is exported in a .step format ? If so, could you point me in the right direction to do it ? I am totally new to cadquery

The current import/export mechanism for STEP files expects faces and not edges.
