Holes Around a Spiral

Helo,
I'm trying to do a SheetMetal model that has a spiral shape and has lots of holes around all the surface. Although tricky, I've managed to get something close to what I want.
The problem is that Onshape is unable to compute all the holes I'm asking it to do. I've tried a Sketch with Linear Pattern inside the sketch, outside the sketch, Linear Pattern of a few holes… My question is, according to theory, which would be the least compute-heavy problem? Onshape refuses to do what I'm asking it to do. Maybe I'm doing it wrong.
Anyways, any help is appreciated!

Can you share your document? or a picture of what you're modeling or trying to achieve?
Like this? Agree a picture would be helpful. Usually part patterns < feature patterns<sketch patterns for regen time I think. You could test your regen times with different methods and check them with the 'show regeneration times' feature.
