But DeltaCAD, with which I have no
relationship other than as a satisfied customer, really IS handier than

your T-square, triangles and drafting scale. The odd thing is that so
few guys my age think so and I really can't understand why.

The sad thing is that guys your age can probably learn CAD faster than
the average high school grad. They most likely remember a bit of 8th
grade geometry from 40+ years ago. :-)

I too recommend DeltaCad for the masses
