I'm making dies for extruders used for pottery work, so I'm cutting shapes into multiple dies at a time. For now, I only have two dies to modify at a time. Here's the two dies with a prism going through them: I have two cylinders here, with a shape going through them. I know I can select one at a time, add a boolean modifier, then apply it and I'll have a hole in the shape of the tall prism cut through the selected cylinder. Then I have to repeat for the 2nd cylinder.
I've tried selecting both cylinders and adding a boolean modifier and doing both in one shot, but it doesn't work. For now, it's trivial, but as I add more dies to work with, it'll be more and more frustrating to repeat the process multiple times.
Is there a way to use the boolean modifier on two or more objects at once?
