Hi, all -- I have CS3 and a colleague in Arizona is struggling along with C1. (Gasp!) Yeah, I told him to upgrade, but he needs a model before he'd be able to get the State even think about possibly thinking about creating a Purchase Order to do the upgrade. So, I've offered to help him out with his model, but I'm a little worried that a file I build in C3 (on the PC, by the way) will overwhelm his poor little C1 (on the Mac). Any suggestions as to what format I should send him the model in? .obj, maybe? Thanks! Dex
