I'm a CAD user, mostly using CATIA V4 on a RISC6000 AIX workstation. Now I'm using Catia V5 on a PC, and my AIX box is gone, sadly. When I need to do something on an old V4 file, I have to log into V4 on someone elses AIX box using Exceed from my PC. This is a terribly slow way to work, and especially the graphics is poor. I'd imagine this is because the PC is acting as a dumb terminal and everything is coming from the AIX box over the network. As powerful as PCs are now (far more so than the workstations) this seems a poor approach. I mean, I wonder why no one's created a way to carry more of the work of running V4 on the PC's CPU and video card, thus getting usable performance without having to have each person have two complete sets of hardware. Probably the answer has to do with software license cost, but the situation is very poor for the user.
Any solutions to help the situation out there? Can a PC better emulate an AIX box in some way to get around this?
