Pete,
Thanks for the info. The DOC was exactly what I was looking for.
I have determined that the drivers I'm attempting to use do not support ADI 4.2
3-D rendering. As stated in my earlier cry_for_help, I have attempted to use
drivers supplied with ACAD12c2, 3DS2.01 & numerous other video driver
manufacturers.
If you wouldn't mind, could you list any known ADI drivers compatible w/CDK.
Thanks again for your help.
Ed
