MODIFY ORIENTATION AND ORIGIN OF FOOTPRINT IN LIBRARY AND UPDATE LAYOUT FROM LIBRARY WITH NO CHANGES TO PCB ARTWORK

We have two PADS Layout v9.1 issues.

 

One, some of our library footprints do not match the reel orientation causing rotation errors in the placement file. So, we need to spin the footprints in the library and then update the board with the new footprint to correct the rotation information in the placement file.

 

Two, some of our library footprints have the origin in the wrong location, instead of being at the point where it should be picked up by our placement machine the origin is centered on a pin. So, we need to move the origin of the footprints in the library and then update the board with the new footprints to correct x,y data information in the placement file.

 

Ideally, we would prefer to make no manual changes to the layout after updating from the footprint library.
