I imported the STEP file but it is giving me an issue... It's still a surface body instead of a solid body. I found the edge giving me issues. I'm not too well versed on using the surface bodies tool though, what is the simplest way to fix this? When I try knitting the 2 surfaces it does not work. Not sure if there are other ways around this.
For some reason my comments get stuck in moderation - admin? Any reason for this?
Anyway, knitting that like it is will create "zero-thickness geometry". That gap needs to be closed.
