So just now I'm cruising McMaster's website for some hardware. I clicked down their easy, intuitive user interface to the part I wanted. Glanced to the left of the screen and see the link to a 'technical drawing'. Clicked on that and just as I'm preparing to do a screen capture, I see above the drawing number a link to 'download'. Oh Really?
Clicked the link and several seconds later I'm looking at a solid model of the part in my CAD program. :)
I have no connection to McMaster and this may be old hat to you all, but I'm happily impressed!
