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.
This is the SheetMetal. As represented in the image, there should be a matrix of holes all around. The regeneration time isn't a problem since the object can't even generate.
The steps I've followed are Spiral Sketch > Extrude SheetMetal > Sketch only the bottom row of the holes > Try to extrude the holes. As you can see in the image, onshape isn't very happy and can't extrude the first row of holes. The length of the spiral is roughly ~800mm, the height 45mm, holes diameter 1mm and distance between holes 2mm.
I'm afraid I can't share the document.
Thanks for your help
