What I meant by a coordinate system was a MAP coordinate system with a datum
(Lat/Lon 83, NAD 83, etc.) If all you have is ACA then there's know way to
tell unless you contact the creator of the dwg. Did you look at Marion's
link? That may be the only way with out MAP3D.

James it is a true .dwg file, so my ACA 2008 tells me.
I am not sure that ACA has "track coordinates"
I just need to plot one point on the map so that I can give the building a
true (ish) dimension for a planning application.
I am just downloading Snag it & I will then be able to give you a screen
shot of the cordinate system in use in the file.
