I've seen this general topic in a few threads, but have not been able to find a solution that works for my particular case. I've attached the imported STEP file that I am having trouble with. The part currently shows up as completely hollow, which leads to some strange-looking results when I insert it into my assembly & cut a section.
I'd like to "fill in" the hollow interior of the part. I ran import diagnostics & healed any issues, so there shouldn't be any faulty faces or gaps...just a multitude of individual faces that don't want to place nice.
Thanks in advance for the help.
