No, that's not how you do it.
Sorry if I was being facetious (I was *just* a little, but also my knee was bothering me so much I couldn't spend the time I wanted to). I was trying to suggest that all you needed to do was search a bit more... until today when I searched and searched and searched the forum and it took me FOREVER to find the answer. So -- I apologize for the implication (which I never *quite* made anyway).
Anyway, the answer lies in what's known as "partial
conforming", a feature insanely useful and yet there are NO tutorials or even detail mentions of it anywhere I could find. Perhaps RL just thinks it's intuitive but while I consider myself fairly knowledgeable on CC3 *I* couldn't find it without some major hints (one major hint is even what it's called).
So, with that in mind -- go to
Conform, Edit Range, and then select what you want to make rigid either by element or vertex or face. Then choose "non-
conform"). There appear to be other options (like creating groups) and I suspect all of this is in the manual somewhere (so you have even more information to figure it all out... now).
