A friend of mine remarked that in V7, with one or more pre-selected faces of a polysurface, one could apply a per-face color (red for example) with the following macro:
It only worked with preselected faces, as _-Properties does not allow subobject selection (even with the subobject selection filter active). Post selection would apply the color to the whole object.
In V8, preselection of faces no longer works with this macro, the color is applied to the entire object no matter what.
These macros are pretty handy for quickly setting per face colors without having to go through the Properties panel and the color picker.
In this case it actually was a friend who also happens to be a fellow modelmaker and Rhino user. I personally hadn’t actually noticed that this was different in V8, he actually called me to ask if there was some setting that had changed, so that’s when I tested.
