Swayback Gable Roof?

[Rich Winsor]

Here I've auto built roofs with curved walls to get the effect you're looking for. The segment angle can be adjusted for a smoother curve.
The caution here is this roof generates a large file size.

Bill, I believe you are on to something here. Forget all these nattering nabobs of negativity who say CA can't do the job. I'm with you up to here (see thumbnails). How did you create the additional segments and how do you adjust the segment angle? File size be danged, I'll just build a bigger rig.
