We constantly have issues whereby holes are being tapped inncorectly for their corrosponding clearance holes.
EG, a hole is tapped M6, but the corrosponding hole is drilled for M5.
This is totally down to user error on input of required hole size and NOTHING to do with Inventor functionality.
Is there a safer workflow method of creating holes or checking that the correct holes have been selected for both mating parts?
Solved! Go to Solution.
It sounds like the users are modelling each hole (the drilled clearance and the tapped) separately. If the user isn't switched on then this type of error can occur.

Not sure how you could model it incorrectly if you are simply using the hole command and selecting a tapped hole? As it creates the proper hole size automatically.
The problem seems to be "unintelligent A-holes" and nothing fixes that faster than creating a vacancy in their seat.
Send them out to the shop floor for several months.
Then have them learn how to use the Hole featues and Bolted Connections.
Would you mind elaborating on how this is done? I understand how this works with a bolted connection, but I was unaware I could use the regular hole command to automatically size a hole. Typically, I project the corresponding hole from part A while editing-in-place part B, place a point on the center of the projected circle, and then use the hole command to create from the sketch point, but I've always had to manually select the size. Is there a better way that will reference the size of the other hole?
No.. not what I meant.. I was simply implying that if you place a sketch point and use the hole command and select a tapped hole it will create the proper hole size automatically..
It wasn't clear or I wasn't reading/understanding the OP's problem properly when I posted that..I wasn't thinking this "clearance" hole was in another part and for some reason was thinking they are just extruding a circle to create a hole then using the thread tool and simply picking the wrong size thread..(even though Inventor typically warns you about that).
Now its clear that his "users" are just lazy and don't take the few seconds it takes to check that they actually used the proper size holes.
...the regular hole command to automatically size a hole. ...
I assume you know about this - but just in case.
Bottom line - Inventor is a professional program and deserves (requires) a professional level of training. The user should know to select the proper clearance and threaded holes for the fastener. Send 'em out the shop floor for a couple of months drilling and tapping. The person out on the shop floor has to understand this stuff - certainly the designer should understand this topic.
What I want (and have IdeaStationed) is reality:
It still bugs me to no end that the entire drilled pilot hole is changed to the minor thread diameter. That's just lazy.
