I don't understand why we are stressing the importance of physical accuracy in projections. Do people expect units to measure as spec'd when projected? When I think of computer projections I think of PowerPoint, and I expect my font measurements to behave as in PowerPoint. When we spec 12pt on PowerPoint does it result in 12pt type on the projection screen which looks like a tiny dot 15 ft away? No. -- cheers, -ambrose
