Awesome! Thanks, Marco. Do you know why trim couldn’t do the job? Is it because the circle edge is so close to the outer edge of the trimmed surface? I will make a note to always try Boolean Merge if trim doesn’t work. I expect I will be importing many models in the future. Any general guidelines for dealing with surface problems like this in the future? I don’t want to bother the forum about every little surface glitch I find. Thanks again!
