How would I go about merging 200 parts into 1?

I’m asking because Boolean freezes or cuts out wherever I try. I’m trying to merge 200 teeth for a planetary gearbox

    Zelig - the best approach is always to post a link to a public document - 5 guys will immediately fix it for you!
    Without being able to see the problem, it's very hard to 'guess' the reason.

    How are you making the teeth? Why are they all separate?
    There is a 10 minute (i think) timeout on booleans - have you tried booleaning smaller groups together?

    The best thing to do is post a link.

    Here’s the link: https://cad.onshape.com/documents/44ee9ad6e0c1f63c08e79b51/w/624b87680efeb4c17344f87b/e/558679588d2bff31a041f223

    im making the gears by making a single sketch face with a tooth, sweeping the face with a helix, and then using circle pattern to to replicate it. From there I Boolean the X amount of parts into one. I managed to do it with a 50 tooth planet gear, a 100 tooth sun gear, but I’m struggling with booleaning (merging) the 200 tooth ring gear.

    Edit: I went back and fixed all of the patterns to mitigate this issue, using method 2 where possible and method 1 where method 2 failed.  The part studio now loads much faster:
