I went and did almost this exact thing in CATIA after your NX video. I also noticed that the dress-up didn't do anything on the canonic cylinder that was produced with the multi-section surface. Does CATIA handle surfaces and curves differently when they can be recognized as canonic geometry?
@@lukrative525 It's not that it handles them differently. It's that they are different. True circles do not have CVs or the like. I will make a video explaining. Good topic.
Not entierly sure if I understand what you mean by "true circles". Alias can build with rationals which use weighted cv's to make perfectly round circles. However. All manufacturers I've encountered prohibit the use of rationals in alias because surfaces will inherit the weighting which will makes alignment work near impossible.
True circles do not have control points. When you assign weights to cv's it causes distortions that cannot be easily mimicked for machining purposes. I will make a video to explain.

@@ClassASurfacing I've only worked a little in catia, but I've been surfacing in alias professionally for 10 years. Looking forward to your next vid.
