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.
