Bug when converting SubD to NURBS

Hello @dalelear and other folks.

I am trying to get nurbs from SubD by using ToNURBS command.
Result, however doesn’t look good:

File is in the enclosure. Can you please check where it can be a problem?

SubD_Nurbs.3dm (745.9 KB)

Btw: I am using ToNURBS within latest release of R6, not R7.


Additional note to @dalelear
I checked similar model and it is not working properly either, but it was working properly in the previous SR one week ago.


Sorry, I broke ToNURBS in this week’s WIP release. It is fixed in 6.12, 6.13, and 7.0 when the version date is on or after Dec 13, 2018. This is the what I’m getting in (7.0.18347.10465, 12/13/2018).


Thanks, @dalelear
I am using latest SR candidate from 11th Dec.
So, will wait for next week release.

Kind regards,

This week we released a new ToNURBS patch pack. I think your file here just got a bit simpler:

Download it and give it a try if you have a chance. We still have a lot of work to do on the feature, but it is a start.
