For a thru hole the tap drill size is different than a blind hole.
Example 1/4-20 UNC. Can I change the blind hole tap size? When I look
at the data record for the blind threaded holes, using the Val-Editor I
do not find the tap drill size for the hole. The table has columns with
the following information pertaining to threaded hole size:
1) ThreadID - This I think is the thread ID size for 1/4-20
Example 10.25x20
2) NND Nominal Diameter Dia of threaded feature
Example 0.25000 for 1/4-20
3) GAL Thread Run-out What is THIS?
So how do i change the tap drill size in this table? I do not see any
value for the tap drill size like I do in the data record for the THRU
tapped holes.
