So my problem is: I haven't needed AutoCAD since AC2000. I have upgraded my OS to Win XP - from Win2K. XP does not support AC2000. I didn't know that when I changed to XP a few years ago. Now I need to get back to the drawing board. I have been looking at the new versions of AutoCAD - 2007 & 2008. Neither of them seems to have the features I want - sketch, parametric dimensions to make the sketch the right size, extrude to make it a solid. All that good stuff. Which - if any - AC product is the latest version of 2000 or will let me do what I need to do? Mike
