We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

What software created the geometry?

Try opening the geometry in SpaceClaim and saving the file as a .scdoc file format.  Attach that file to your project in Mechanical. That should not give you any plugin errors.
