Need to create several thousand holes on a part

Hello,

I am currently trying to create some fairly simple parts (can be a drawings as well) that need to feature up to several thousand holes (the most which has about 15,000).

An example of one would be placing 0.002mm diamater holes on a 1.4x1.4mm block, with a pitch of 0.024mm.

Obviously, trying to pattern this many features has either failed to load, or has taken forever to load! I was hoping someone may know a way around this feature-patterning problem (other than using the feature or sketch patterning tools in one sweep). Thanks!
