Ballooning artefacts on STEP files

 From:  pastasaus

Hi folks,

When importing client STEP files, I'm sometimes seeing these weird ballooning artefacts particularly around screw heads. It's causing some meshing issues that I'd like to avoid so we can optimise the model for animation downstream in our pipeline.

Any thoughts on what might be causing it and if there is a straightforward fix?

Thanks!
