It would be nice to be able to invert the Reflect copy (“Invert reflect” command?), in order to be able to design shapes that are mirrored in two directions, such like the example below. The yellow plane represents the Invert reflect plane.
It looks like the radiate (kind of polar array for subd) with 2 copies could do the trick.
Damn, my Rhino 7 does not have a Radiate icon, even though I update it regularly. Long time ago I replaced a few icons with my custom drawn ones, but I 'm not sure why there is no Radiate icon and button in the “SubD tools” panel… Hopefully I don’t miss any other newly added tools not present in my SubD tools.
Other than that, your suggestion worked just as I needed, thanks!
