Modeling subD fork offset edges not rounded

Rhino
1

Trying out the SubD in 7 from Fork video from Brian James. Mine does not seem to offset to smooth edges. I need to take the extra step ( not in video) of removing edge creases. What am I doing wrong?for web 7.3dm (137.2 KB)

Hi @Et_Rec
Not at my computer right now, but IIRC, previous versions of the V7 WIP didn’t crease the offset result - that’s why Brian’s edges are rounded. For now, you will have to run RemoveCreases and select the object to get the “pure” Sub-D result. I believe that adding a Crease Yes/No option is already on the list.

Thanks for answering. I’m not using WIP, but rather 7.1.20343.9491. Anything I’ve tried to offset from the SubD “create Plane” comes out with a creased edge. I don’t see any option to add Crease Yes?No . I vaguely remember the same problem in T-Splines . Followed a video there as well , and it offset with a sharp edge, when it did not in the video lessen

Could it have something to do mesh settings (smooth and slower) . I do remember problems once in Rhino 5 with parts of the "command line"would not work in high-resolution screens.

Hi @Et_Rec
What I meant was: The video is from the WIP period, where the Sub-D offsets were not creased. Later on in the WIP process (and in the final version that you are using) the Sub-D offset will indeed crease the result. You will have to run RemoveCrease (or RemoveCreases, I don’t remember) to soften the result. Making an option to crease/not crease is on the wish list for the Sub-D offset command, and will hopefully be made available in a later SR.
