open source equivalent to MAP 3D? for a MAC?

[scubadoo]

Afternoon all,

I used to use AutoCad Map 3D a lot at work. I'm self employed in a different field now but make guitars in my spare time.

I found Map 3D excellent for producing scaled plans of guitars from which to make MDF templates.

Please can anyone recommend a free open source alternative that runs on a MAC?

apart from basic CAD functionality i'd like to be able to geo-reference rasters as well if poss. I also need the offset function for laying out fret spacings.

I also have CS5 and was wondering if Illustrator would work.

Cheers

Dave

Take a look at OSGEO.org. But most of the folks there like Mac as much as they do Windows.
