Automatically Changing Hole Depths

[Anonymous]

This feature of Inventor - to automatically change thread depths - is stupid, and moronic, and dangerous.

I have some parts with threaded holes - the holes have 1.2" of thread (because they require 1.2" of thread).   Among other things, it was decided to change the tap drill from thru to blind - so I made the revisions and released the parts for manufacture.

*However* Inventor automatically changed the thread depth to .945 - which isn't enough thread.   The fasteners torqued up ok, but they did not generate the required clamping force.  We ended up with fine jets of 4500 psi hydraulic fluid.  (Look up 'injection injury' and click images, you'll see why this is undesirable...)

Is it still there in 2016?

Hi! There was indeed a change in behavior in terms of the spec hole depth. Before 2015 and earlier, the Hole/Thread table does not have a dedicated thread depth columns. We were complained by the users that the hole features do not obey standard. As an enhancement back then, the depth columns were added to Thread.xls. And, the depth is honored. If you want to revert back to the old behavior, there is way to do that actually. You can simply go to \Design Data\XLS\folder -> find Thread.xls. Simply clear out the values in Thread Depth columns. Then you can the depth value manually. Then, the values carry over to next hole feature.

Many thanks!

Johnson, the whole procedure should be better. There's a standard difference between thread depth and the accompanied hole depth.

So, if I'm changing the depth of an existing threaded hole, the drilling hole should be changed accordingly with this difference, too.

That's the normal workflow. And that's what we need.
