I want to install Ubuntu on my lappy, but the only thing keeping me is I wouldn't be able to reinstall CC2. I took a look at some other mapping software and was generally disappointed. Inkscape looks promising though, except for one thing:

I am always using the modifiers to construct objects in CC2 (midpoint, point on, endpoint, perpendicular to, parallel to, etc). Is there a way to achieve these functions in Inkscape, or is there any other software which can do this?

I am also considering getting CC3 and trying to run it on Wine, but would like to know if it works first. Has anybody tried running either CC2 or CC3 on Wine?
