Hey, guys, think of future generations, put something appropriate in the subject header!
The two posts to the topic so far did not mention the command that makes initial library origin irrelevant. When opening a new footprint window, after cancelling the wizard, place a pad, doesn't matter where you place it. Then Edit/Set Reference/Center will place the origin at pad center. If the beginning view window is too large or way too small, Z-A will set the pad to fill the screen and Z-O a few times will give a typically usable scale. (Center in the Set Reference command refers to the extent of all copper in the footprint; the resulting reference will be the midpoint of the extremes. For most footprints, I prefer to use center reference, it allows rotation without movement of the component center. For example, if I have polarized capacitors with pin names 1 and 2 and it turns out that these need to be rotated because of a bad library footprint or symbol, they can be rotated with global edits and pads remain in the same places, only the pad names and component rotation values are changed, plus any asymmetrical non-copper primitives. If I have a QFP, I can rotate it in place. Pin 1 center, with SMT components, does not have a fixed relationship to the physical part, so I'd think that assemblers for autoinsertion would want centroid plus rotation, another reason for using center reference.) The Footprint Wizard should not be default, unless possibly the Wizard is so much improved that it becomes useful for the majority of parts. Right now it just adds keystrokes. We have elsewhere discussed possible improvements to the Wizard.
