The set cplane to object command does not work on the subd object
Hi all ??
In your video the CPlane is changing when you select different locations on the SubD object.
Do you mean that the CPlane is not changing as you expect?
Not working properly
Can you upload the .3dm file with the three objects?
Added: Try switching to wireframe display mode and see if CPlane works differently.
Thank you for reporting.
