OK this may be a dumb ques.... but here goes. I use Vectorworks CAD software, and am thinking of an iMac for the office. However I also need something portable to carry around showing clients pretty pics on to sell my designs. The ipad sounds perfect right? BUT what I really want to do is show them 3d walk throughs of my designs... kinda like mini movies of their new garden. eg http://www.youtube.com/embed/euxbCQ8S6F0 I can create these in CAD. So here's the ques... what kind of format would i need to save these walkthroughs in to play on ipad? Can you see any probs I might run into? I'm trying to find out the formats I can create in VW.... but maybe someone out there uses it and can tell me? Thanks
