If you want to make the assumption that most buildings don't have any curves in their roofs...

Then take your point cloud, extract the largest polygons... There are classical algorithms for such things.

From the polygons, turning that into a plan should be quite straightforward.

While ML could be applied... I think you'll get better results quicker with classical methods.

Wonderful. I did not think about curved/arched roof surfaces. The last thing I want to do is make this more complicated than it needs to be, so thank you! If you don't mind, where might I find an algorithm to test out?
