Hello, this is the beta version of my upcoming project. It is a tool designed to shape roofs from a basic curve outline or by meshing a plane. If you’re interested, here is the file for testing.

Interesting. Thanks for sharing! 
Some progress is being made: independent roof slopes are now defined by the curve tilt (or the custom ‘tilt’ attribute of the mesh vertices). So far, this is only working in boolean mode. Implementing it in extruded mode, which should ultimately be more reliable, is proving to be more challenging.
Excellent… thank you.
