I created a list of many pins/pads with names and sizes using Footprint Edition. later on, I want to change the distance between each pin/pad to make it 2mm instead of 1mm. I had to do this manually.
is there any automated way to position pins/pad a certain mm from each others?
Yes. Use the “Array” tool.
It is much easier to create a new footprint using the array tool than change the distances between pads on an existing footprint.
Using the footprint editor, place a single pad.
Right Mouse click that pad.
Select: Create from Selection > Create Array.
This function is also available in the PCB editor.
