@Keet
Thanks for your appreciation and encouragement.
1.

remember this challenge?

Of course and I've tried again.
Is not so perfect as your but it is a try.
The file:https://www.mediafire.com/file/ebavzdlbpbuu4ug/RoofChallengeD.sh3d/file
And a picture:

Take a look at the slope values of the faces.

2.

You do realize that this is very close to a multi-point 3D shape generator?

I do. It's been on my mind for a long time (probably since the beginning of Shape Generator).
I'll see what I can do.

3.

Replace 'roof' with 'shape' and it's there.

If it were that simple...

4. The RG v.5.0 beta14 is far from usable for common users.
I made it, I use it, but it is very difficult to use even for me.
There is still a lot of work to do and I don't know if there is time for me.

5.

And I am definitely going to abuse it for that

Unfortunately, you and others (including me) will have to wait. [:((]
