Hi Riko - what method are you currently using to make holes? Are you possibly making an extruded cylinder solid to use as a cutting object in boolean difference?

If so then you can save some time by instead just drawing a circle curve object to use as the cutting object instead of making an extruded cylinder.

The booleans have automatic extrusion built into them, so you can create a hole just by drawing a circle and using the circle as the cutting object directly in boolean difference without doing any other steps.
