sweep2_setup.3dm (171.3 KB) Maybe I’ve missed something. But something seems up with the Sweep2 Output SubD option. It seems to sort of remember the structure of making a NURBS surface, and applies to the next created SubD. And actually even creates two different surfaces from the same pic…

Hi @Jonathan_Hutchinson Thanks for the find. I am able to repeat here as well. I have created a bug report here. https://mcneel.myjetbrains.com/youtrack/issue/RH-58540

Hi @Trav You’re welcome - glad to have noticed, and thanks for taking the time to repeat. I had noticed sometimes I got SubD Sweep2s that followed the rails and some that didn’t at random. Do you think the Output SubD will remain integrated within vanilla Sweep2, or that a SubD Sweep might be peel…

Hi @Jonathan_Hutchinson the reason some of your curves fit and some do not depends on the curve structures. We call these “SubDFriendlyCurves”. You can read more about what makes a curve SubD Friendly here. [image] SubD Friendly Curve SubD Hi David - from a presentation t…

Cheers Trav for the link. Yeah I think I’ve noticed the trick for SubD friendly - is it the little grey dot when points are on? (and SubDfriendly+ in _What) [image] Edit: I posted that image BEFORE reading the link :sweat_smile:

Hi Trav - this seems to be halfway there. The surface output is coming out right everytime as it would be expected, regardless of whether or not you have output a SubD the previous time. But with the SubD output, only the dense version is possible (albeit, a version which doesn’t fit the rails perf…

Hi @Jonathan_Hutchinson @lowell may have some more insight here.

No more insight. Simple sweep is prohibited for subd output because it usually doesn’t hit the rails.

Thanks for the info - got it. I would maybe argue for allowing the simple option - it wasn’t so much that the result was a problem in the reported bug, but rather that it would yield completely different results with the same options. Someone mixing workflows might end up with an unnecessarily compl…
