Hi Riko - but all you have to do currently is draw a circle and do boolean difference.

That's not very many steps already...

What kind of steps were you thinking of instead?

If you're placing holes in a repeated pattern drawing just one circle then allows you to use the array commands to replicate the circle into a pattern and then you can do just one boolean difference using all those replicated circles as the cutting objects.

Is it that you are always using a circle of a specific radius?

If that's the case then maybe the QuickCircle script would help, see here:
