I have been surface modelling and I always find it difficult/annoying that I can’t see end result (after trimming/splitting), what I do is lay out a buncj of surfaces hoping that it will look good once everything is splitted and joined.
What I am looking for is a way to split all surfaces with eachother, and when turning on control points I can edit the original surfaces and the splits/trims will automatically update instead of having to manually untrim surfaces just to split again. Does anybody have a solution for this? I really thought record history would allow this kind of operation. Maybe a plugin exists for this?
