1. First step after adding a new bore design feature to a part is to define the position of it.
2.a) In the next step you can define the diameter of the in this case not threaded bore and add a chamfer to it. If
this sequence is fulfilled the chamfer diameter is chosen automatically to a useful diameter.
For example in case of adding a chamfer to a 10 mm diameter blind hole, Creo predefines this chamfer
diameter to 12 mm. This works only if the hole has no thread.
2.b) Contrary to this procedure Creo is choosing a completely wrong chamfer diameter if the bore is threaded.
For example if you want to create a M5x0.8 thread and then klick on the chamfer button the predefined diameter
is 11.20 mm, which is by far too big.
Maybe there could be implemented the same functionality for threaded holes as it is well done for non threaded ones. This would save time, especially when there are a lot of different threaded hole diameters in one part, because it would not be necessary to change the chamfer diameter permanently.
