* Where I put a number in {}, i.e. {2.0} I'm, referencing https://wiki.openstreetmap.org/wiki/OSM-4D/Roof_table which is a great reference for thinking about all the various roof forms.
Couple of requests to add for consideration if at all possible:
1. If I understand the principle, moving the big yellow dots changes the angle of projection away from the perimeter line. If so, it'd be useful to have an overlay showing what that value is.
2. On each perimeter line have the ability to disable that plane of roof. This would be good for gable ends {2.0} with already peaked walls below, or unusual roof shapes.
But otherwise this looks awesome. Now all we need are rooflights!
A couple of other pie-in-the-sky ideas coming to me:
3. A segment or points get an elevation parameter which I think would allow half-hipped {2.3}, and saltbox {3.0} and "cutouts" {3.0 free outline example}, but that may not be possible based on the library.
4. A slightly easier idea for half-hipped and the like is to use two rooms. Room one uses the campskeleton to generate the planes, and room two is used to clip the generated roof. So the campskeleton segments for the half hipped ends are further out, and the clip room segments are closer in, causing that stubby little end plane. I hope that made sense.
