As awesome as the trimsheet/hotspot functions are, the standard 'mark by angle' option is simply unsuitable for dreamuv-like trimsheets. I have to run a ~30 degrees mark-by-angle operation and then painstakingly enclose the quad strips and panels manually. In the attached picture you see what the algorithm should do automatically. #1 are standard strips (could also be panels, with rows and colums), within a certain angle threshold. Whenever there's an "L" like corner, it splits it into another strip, which could be a single quad (as in #2). Whenever the angle threshold is exceeded, it breaks it into another strip or single-quad, as in the #3 highlighted areas. If we get this functionality, it'll be a massive booster in productivity for this kind of UV layout work.

Hey. Could you please provide the geometry shown in your screenshot for a better understanding of the task?

@ValerieDusk Sure. I’ll do better, as this specific model has very few “panels” (quad areas with rows and cols), I’ll send you another one which is more complex, and record a video showcasing my thought process and editing, from mark-by-angle to hot spotting. And the model, of course 😊

Thank you.
