Pete,
Yes, I use TurboCAD and it can view just about any of the typical CAD formats. One of the machining operations I want to try on the rotary table is milling rounded ends on stationary steam engine linkage parts. There is a clever way to do this safely without a rotary table (and I think it was Randy Richard on YouTube who demonstrated the technique on his Bridgeport) but the rotary table would be universal for different sized radii rather than using a jig.
