Ubuntu / Linux version of Solidworks?

Does any one know if Solidworks will ever have a linux / Ubuntu version. Our one year trial running Ubuntu as our core has been successful and now it is time to find replacements for the remaining Windows applications and phase out all the Win machines. It would be nice if Solidworks would port this to Linux however, I am open to suggestions (dreaming) of a linux substitute for Solidworks.
