Acme Thread

Would be nice to have Acme threading into the hole feature menu.

Edit: the forum modified the formatting so if it doesn't make sense i could attach is as a downloadable link?

I needed to do with with trapezoidal lead screws, so I made one for ACME as well if i needed it, you can add the data below your thread spreadsheet in Design Data folder in a new tab, change the sort Order to whatever the next number in your list might be.

This was AI generated, the size and TPI it created was correct, but external and internet sizes might be off, the thread runouts were added in but i don't see why you would need those, so use with caution, you can add lines as well to add the other thread sizes.

I did vote for this hoping Autodesk could just add more thread designations.
