PushPull fails to recognize the area for the 4th situation:

Rhino thinks a while before it gives up.
I already moved the sphere seam, didn’t help.

The curves were made by projecting parallel lines.

I have occasionally seen the need to pull the surface curves to the object when this happens.

3

Already tried _Pull…

For an object like this sphere or something more organic it would be nice if the intersection curves were not necessary and the regions would be detected based on section planes.

6

Something to play with, the sphere is different from the former file, it is new.

_Project the 4 lines to the sphere and try.

Also I see that the preview while dragging is really slow.

Found a solution.
The cross-like curves are trimmed like so now.

Preview response is still not good.

I have noticed that on deg 3 surfaces the preview lags a bit. That is something that @Joshua_Kennedy may be able to tune up going forward/

Yes, I’m seeing the same. Thanks for reporting. I opened the issue here. I’ll look into the slow preview at the same time. I have a pretty good idea why it’s slow.

Preview is much more responsive now.

Glad to hear it! There’s now a “Loose” option in PushPull that’s used for the preview so it doesn’t spend so much time refining the result. I also put in a fix for this reported issue yesterday. There was some issues with the splitting curves crossing seams. We’ll see if it makes it past the testers.
