RE: CAD at Home
TurboCAD 7 here. I feel that I'm about 70% familiar with it to the point I can do the CAD faster than I can do the same drawing if I have to so much as pick up a ruler to use with a pencil. Current version is 9 so I guess I'm obsolete but it does what I need so I don't feel much pressure to upgrade. Bought it as an upgrade from ver 5.1 off the net. Bought the original 5.1 at a discount price from the local software store.
