I sometimes encounter an error converting a STEP file to a GLB file using CAD Assistant. I have attached an example file that causes the issue I am referring to.
I believe this happens every time the exception "RWGltf_CafWriter skipped node X without triangulation data" is raised.
To reproduce: Open STEP file, save as GLB file, open GLB file. An error such as "Scene node # refers to non-existing mesh" is raised.
I am using the latest CAD assistant version with OCCT V7.6.0.dev backend.
Let me know if you would like additional details.
