You have a .pvm (Parallels Virtual Machine) file installed on a Mac that is running Parallels in order to run CAD. You are wondering whether you can install that same .pvm file on another Mac. Essentially, you would be using a standard .pvm file for each Mac you set up in your office.
Yes, you absolutely can use a standard .pvm file to ease the setup of a new Mac (or the installation of Parallels on a Mac you already have in your office).
After you set up the computer using this .pvm file, you will then want to remove that Windows user and create a new user account.
You will then also need to reactivate any software, such as F/X CAD. Need help reactivating F/X CAD? Follow the instructions linked here.
