SubD Toggle, one is enough (TAB)

Hi just wondering when I use the Tab for SubD display from smooth to flat, it simply doesn’t change the display and I also pressed the Toggle Button for the SubD Display and wouldn’t either work that way too and the commands pop up but no change

Just wondering what I can do to see the change in the display



Hi Sam -
Just to troubleshoot this - could you make a SubD box with the SubDBox command and then hit the Tab key? Then open the command history (F2) and copy-paste the command information here.
Also run SystemInfo and copy-paste that information here.


I have copied the command history below and System Info pasted below



Command: SubDBox
First corner of base ( Diagonal 3Point Vertical Center XCount=2 YCount=2 ZCount=2 )
Other corner of base or length ( 3Point )
Height. Press Enter to use width
Command: '_SubDDisplayToggle
SubD display changed from smooth to flat. 1 SubD changed.
Command: _CommandHistory

Thanks Sam -

Parallels is not a supported platform so display-weirdness is to be expected.
As far as I recall, this is the first report of the SubD display toggle not working on Parallels, but the, it’s possible that you are the first one that tries.

I wouldn’t count on this getting better and recommend that you look into using Bootcamp to run Rhino for Windows on Mac hardware or to just run Rhino for Mac.


Thanks for getting back to me.
Do you know if I i run Rhino 6 on my Mac, can I operate the grasshopper that comes with it on Mac not windows ? Or does the grasshopper that comes with it only operate on windows ?



And is there a working in progress for Rhino 7 on mac ?

Yes Grasshopper works on Mac, and yes there is a WIP for Mac.
