But... being able to import a model of an PCB into your mechanical design as a part, now *that* has value. What I'm interested in is getting the screw hols in the right place, making sure that the big 'lytic caps don't bonk into a rib or strut, and make sure that the heat sinks actually *do* end up in the air flow. -dave
