No bevel on version 1.1.18 and higher

[brianlow]

I think the bevel feature, and maybe concave faces feature, were broken in v1.1.18.

Notice the left image:

• the edges were rounded
• the flat horizontal surfaces only reflect on part of the surface indicating the surface is not flat
• the internal reflections are more complex and less rectangular

These images were generated using a python script that performs additional environment setup. However was able to reproduce using the Blender UI

Steps to reproduce (edited)

1. Blender 3.6.22 on MacOS 15.4
2. Import -> LDraw
3. Go to the ldraw/parts folder, pick 6141.dat
4. Choose Resolution: High resolution primitives
5. Choose Show LEGO logo on studs
6. Ensure Make individual studs is unchecked
7. Click Import LDraw Model

Expected: 1x1 dot with bevelled edged Actual: 1x2 dot with sharp 90* edges
