Error converting STEP file to GLB

Hello,

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.

Your archive contains only glTF file and not original STEP file, so that it is impossible reproducing the issue.
Please share the sample STEP file.

Thanks for the sample. It seems that this issue has been already fixed in OCCT.

The latest version of CAD Assistant doesn't yet include this fix, but you may install a beta version (1.5.1 beta 2021-02-14) on Windows platform by specifying "Beta (Preview)" update channel in CAD Assistant settings (first tab at the very bottom).
