I'm making an archway thing and have got stuck trying to only make a certain part (the highlighted faces) of it curve:
I've used an array and curve modifier to get some little support things to curve correctly, using just one object. The trouble with that is, modifiers affect an entire object, whereas I only want to affect one section of the main arch object.
What is the best solution to this problem? (I'm aware of how bad the... topology(?) is)
