SubD - ToNurbs bug

Hi there,

using the _ToNurbs command on a SubD object with the option _DeleteInputObjects=Yes deletes the created brep. Should’t it delete the input SubD object instead ?

thanks,
c.

If that’s the case that’s certainly a bug. I don’t see that happening here though. Can you post _SystemInfo?

Hi @Gijs, i’ve found it’s not as easy as switching the _DeleteInputObjects Option to Yes and pressing Enter to repeat the bug.

If i open Rhino, switch that option to Yes, everything works as expected. But if i do enter the SubDOptions before and toggle the ForceUpdateFacePack and ShowFacePacks options, then go back to the higher level of the command options, it somehow leaves the command in a state where it never creates a brep, regardless of the DeleteInputObjects state.

I have to close Rhino to actually reset the command so it creates a brep again. I’m using (8.14.24325.13001, 2024-11-20), please find my SystemInfo below.

i already had reported this issue here but it does not seem to depend on the option ForceUpdateFacePacks at least not on mac.

RH-84973 is fixed in Rhino 8 Service Release 15 Release Candidate
