I seem to remember that there's a bug in the way the hole command uses a custom user-created hole standard, but I don't remember if it was ever resolved.

As per the CATIA V5 help files, you can set a mode to define how your countersink is controlled, relative to countersink angle, diameter or depth:

So, I have set my new standard to mode 2 so that I can define the countersink by diameter and angle:

And yet, when I select it in a model, the mode sets itself to depth and angle, and the fields are filled with the wrong figures and greyed out:

Anyone remember this? How to I fix it?
