I really enjoy using my Mac computer, and use it for everything in my drafting/design business. I did most of my drafting on AutoCAD LT, but recently started using Revit which is only available on PC. I found Parallels and after some research I decided to try it. Parallels was extremely easy to install and use on my Mac computer. It was nice to have a free trial period to try things out before purchasing the program. The Revit program does take a lot of memory to run properly, but Parallels makes it easy to adjust the amount of memory my Mac allocates to Parallels to make programs run better.
