I used the crossover office that came with my Xandros v.4 Premium to install Vectorworks 9.5 Architect.
It is functional and very quick (certainly for all basic functions - I have not tried the Open GL, or Any large rendering as yet).
The only issue is that the buttons appear to be greyed out all the time, even though they all work perfectly when you click on them (this makes it more difficult to tell which buttons are which, but you get used to it) and some of the fonts in pop-up messages (eg. "Do you wish to change to plan view") are either very small or formatted bold.
Still, not a bad effort 😇
