Me again, with more questions for the experienced users. I won't be able to get any formal training for at least several more weeks, and I'm impatient to get going I guess. Can anyone help me with getting centerlines on my drawings? That's one issue. Another is with printing. Is there any easier way to see if you've got the setup you want than trial and error? Also, how can I set up a specific model printer if it's not on PTC's list already? We just spent a lot of money on an HP4500 plotter and also have a Laserjet 5si... I don't see anything newer than a Laserjet 4 on the list of printers. Help?
