When i tried scaling a smt pad using the scale pad feature on only a oblong pad it does not scale it properly. This only happens if I set the x and y percentage at a different percentage and on a oblong pad (on a rectangular pad is fine). if the percentages are the same then there is no problem.
When the percentage is different, it twists the pad instead of reducing accordingly.
We have updated FAB 3000 to handle scale of custom oblong aperture shapes. Here's a tutorial movie showing me performing scale pads on your sample workspace:
