Stiglr, I do this by getting the position of the point I want in the origin at the outset, and then calculating how far I want the entire object moved to put them there.
Any rotations are done the same way (although a 'rotation counter' that shows how far you've rotated on what axis right now would be nice), before the moving process. That should allow you to get the right (within 0.01 unit) measure, and most often the exactly correct measure.
