Wasn’t there a way to make extrusions and sweeps default to splitting on tangents?
Eric
Hi Eric - Extrusions made as extrusion objects (UseExtrusions command) should split; but as polysurfaces you need the option and no, I do not see a way to force this other than using a macro
! _ExtrudeCrv SplitAttangents=Yes
@ejolley - this has come up recently here - can you tell me why you would like the splitting by default?
-Pascal
Most times I prefer to have the rational geometry- planar panels remain so and can be extracted and circular sections have centers. Simpler geometry is better generally for machined things.
I’ve been using DivideAlongCreases to get what I need but it would be great to have the option at creation. I think in V4 there was a global option that set the splitting?
Eric
Hi Eric - some individual commands like ExtrudeCrv have the splitting options. CreaseSplitting is still a global setting but on by default - you should only ever need to deal with that if for some reason you want to generate kinky single surfaces.
Sweep1 should respect simple rail curves unless refitting on the rails is set
I guess if you have examples of where you use DivideAlongCreases SplitAttangents=Yes where it seems like you should not need it, post or send those to me…
(one thing is, you may have Nurbs curves as input where SimplifyCrv will make a polycurve from it with say arcs and straights)
-Pascal
These are cases where I’m definitely starting with polycurves (lines & arcs) and I get un-split results with sweep1 for instance.
CreaseSplitting says it’s enabled but i get results like the attached.

It is set to True
Hi Eric - thanks, got it - so the non-splitting is in the cross sections and not the path.

Exactly!
