When creating a mounting hole pattern, square or bolt circle, in Creo I would create holes in one part and then create a single hole referencing the seed of the pattern on the other part and then get the same pattern on the second part.  Super useful when you need to make changes to the initial pattern. All the holes in the assembly would follow the master pattern.

I'm pretty new to SW so there may be a way to do this but I have not figured it out.
