I recently install parrallels 5 on a MACBOOK PRO 2010, I'm running windows 7. I am a student studying Computer Aided Drafting (CAD). That's the reason for installing windows, I have AUTOCAD 2011, and MicroStatin V8 installed. My problem is all of my drawings are saved as Microstion, even if they are AOTOCAD drawings. It's not a big problem to open them up, I just do the "open with...". The problem is all of my AUTOCAD drawings have the double red bars of Micro Station on them, so when I turn a drawing in I loose points for file management. Obviously I did something wrong when setting up Paralles, but I don't have any idea what. I guess it's some default setting, but I can't find any way to make any changes to Paralles: i.e., a control panel of some sort? I know I must sound like an idiot, and when it comes to computers I am! I am a 50 year old "dis-located worker" in the process (or I should say attempting retraing). Before this I only surfed the internet, so your help and patients will be greatly appreciated.
