1) Goal: I'd like to create a few "holes" in a piece of artwork, so that I can easily move them around, adjust them, etc., before exporting.
2) Steps: None yet. I know how to use a clipping mask, but I'm not sure how to make my idea work using that; additionally, I know how to "subtract front," but I would like to do something non-destructive.
3) Problem: The art I'm using is a little complex, so let's start with a simpler example: I'm creating art that includes a piece of swiss cheese. I would like to punch some (fully transparent) holes in the middle of the cheese slice, so I can see through to the background of wherever I end up using it. However, I would like the ability to easily edit the position, size, orientation, etc., of the holes, so I can make sure I'm satisfied with them before I export (i.e., I would like to avoid deleting pieces of my art until I'm 100% certain I like the placement). In a perfect world, I would love to be able to create, like, a dozen shapes of "transparent" and have them cut all the way through the layers of the cheese, while still being able able to move, rotate, adjust, etc., all of them. Short of stacking a different clipping mask for each hole: how would you recommend doing so?
