How do I use the HOLE tool to tap an existing hole?
We use pre-drilled shafts (1/2" hex rod with 0.159" hole down the center.
I want to tap the first 1/2" of the hole for 10-32 and make drawings to send to Fab.
The hole tool fails, saying that the hole doesn't intersect any existing parts.
How do I do it?

You could direct edit the exiting hole (if imported geom) to remove the face or offset it in a little bit. Then use the Hole tool to put a correctly specced 10-32 with 1/2" of tap. If native geom, just use the Hole tool to start with.
The existing hole goes for the full length of the rod, and is exactly the tap drill diameter for the thread we need.
Is there truly no way to apply Tap info (and graphics) to part of an existing hole?
Can it be done with FS? I tried to modify Hole.fs, but it is extremely complex, and uses a lot of internal-only code
Can I use FS to apply thread property/attribute to a face so callouts work correctly in drawings?.
UPDATE, this doesn't exactly work.
offset face in → tap → offset face out causes the visual threads to disappear from one end of the hole.
Creating half the part and then mirroring the part, also causes one end of the threads to disappear. below is mirror-new vs mirror-add.
mirror-new → boolean union does the same thing
even though the visual threads are gone, the hole callout in drawings is "correct", however, it is actually wrong, because we do not want or need any drilling operations, as the hole already exists in the stock. any way to get rid of that, or create a library of custom callouts?
It sounds like the old fashioned way of a simple thread note pointing to the hole in the 2D is what you need. Me personally, that's usually what I do, even with the fancy built-in callouts.,
I think adding a split in the face in the middle would allow threads to show at both ends?

There was also a "tag hole" FS somewhere
yes, I added a split, but it seems like that part of Hole is buggy. also, the visual threads change depending on where you place the Z of the hole location mate connector. not the start plane, the location. this also seems buggy. and beyond that, it feels like a huge deficiency that you can't tap an existing hole.
I will look for that FS. thx.
EDIT: I found tag hole and simply tagging a hole is 1800 lines, wow. I need to find the core of it and just make a "tap 10-32" and "tap 1/4-20" which is 99% of what we use.
