Josh, Thanks for the post. Using the alt key to mate concident is fine when the two surfaces to be mated are not exactly parallel to each other. Yes, it can be done, but your macro has less keystrokes and more consistant results.
Josh M Thanks for the defense of my innocent macro tip :) I can fly through assembly mates with'em. I hope this give some people ideas about speeding up the process/reducing keystrokes for other commands.
