Seems like there are a lot of standard data files in your Pro-E setup, that just aren't documented well. You have to look for them, figure out how they were made and what editor would work best etc... but eventually with trial and error you can customize them for the things that PTC left out. We have had to add or modify the sizes on several of the steel profile data tables for EFX module, so that they contained common sizes we use. I'm guessing the same may be true with these hole files... they gave you a starting point, now perhaps you just need to add to the data in these files. Again, I've never messed with these so I don't know if they would be able to give you what you need or not. Just a thought. Thanks!
