Is there an Altium feature or technique that allows pads to be referenced in location by their corner instead of their center?  Most mechanical drawings use corner references for pad locations so being able to use that data directly would be convenient and less error prone. I most often like to drop pads of correct size near their correct location and then use XY coordinated to get them into position. Of course for evenly spaced pads I just array them.

No way that I know of.

You get used to recalculating pad centre positions from drawings in your head after a while....

You could modify the PCB library footprint and set the reference point in the corner but this would require doing this for every component, otherwise I don't know of any way to do this.

The drawings that show pads dimensioned like that are because they are done by someone that does not know how to dimension footprints, usually a mechanical draftsman.  :)

Yes.

But you don't want to.

The pad center is used for trace connections, so you'd have all the traces connecting to one corner.  How bizarre.
