I have a composite curve created from a projected curve and edge converted into entities. They form a closed profile, and I have a rectangular shape following that path. Getting to that point took me some time, but the problem I'm facing now is now that I have the lip I'm looking for, the inner wall faces have what look like to be asymmetrical irregularities. I suspect it is because the rectangle profile I've used is "poking" through the wall at points, but I was under the impression that if the sweet guide is literally converted from the wall edge, how could this happen? Thanks, hoping to figure this out one & will post if I do, but could really use a second set of eyes maybe. Thanks again.
