Yeah Chris, there is a mirror function even in C1. Litst, this is pretty cool, but I already use Amapi 6 for almost everything. I'm not sure just how familiar you are with Amapi, so you may not be able to anser this, but I'm wondering: can you do anything with C2's sub-d that you CAN'T do with smoothing and dynamic geometry in Amapi? Otherwise, I don't see much new here that really grabs me, other than the advances in the rendering area (which is obviously not to be taken lightly).
