I use Creo Parametric 7.0.8.0.

I have a problem with EZ Tolerance extension, my problem is described bellow. 

 I was using set of a shaft and a bearring with a hole, firstly I calculated it by hand ańd then with EZ Tol., but the results were not same.

Here are my calculations:

1. Nominal Clearence

Hole-Shaft=(0.3760-0.3745)/2= 0.00075 mm

2. Maximal clearence

3. Minimal clearence

EZ Tol did the Nominal clearence good, but not the min/max clearence. (I attached some pictures with the assembly). 

Thank you.

I had to set Assembly Shift to Maximize and Attachment to CENTER-CENTER and then it calculated to be 0.00075 +/- 0,005750, which is right. Thanks anyway 🙂

Is it possible that your EZ tolerance setup includes positional tolerance and your hand calculations do not?
