When did PTC stop filling in hole information in the .hol files?
Starting at 9/16 they do not have any information for clearance holes.

Why?

    My WF2 hole files (2005) are also blank for clearance hole information, so it has been a while.

    Easy enough to modify and add what data you need.

    I have often modified the tables for the drill size that the shop wants rather than use the PTC supplied data.


    Thank you,

    When I did a corporate setup, I also edited the hole tables... I eliminated all but the standard coarse and fine thread versions of both the standard and iso styles... That way I didn't have someone mistakenly using a hard to obtain thread...
    just a thought...

    It's because the information comes from the Machine Handbook (table 4 "Tap Drills and Clearance Drills for Machine Screws with American National Thread Form")



    The table in the handbook stops at ½ inch.
