Editing a morph in AC is a bit of a pain. It would be far more convenient to be able to do so in SketchUp. Could it be possible to have context menu option "open with" and then Sketchup (and possibly other software) as sub menu option? You then make edist is SU, save and close and it reloads in AC.
I have a non solid morph that I could solidify in SU in a matter of minutes oppsed to AC where it is very very slow.
