Can anyone tell me how I would script up the selection of a large number of components. For instance, let's say I have components "element1" through "element12000" and I want to select every 300th element?
It depends what you mean by "element"
ActiveDocument.Components("U1").Selected = True
ActiveDocument.Nets("VCC").Selected = True
You can do this with components, nets, jumpers, labels, pins, vias and more. Check the PADS Layout Automation Help for details.
