ISO tolerance table

I think go and enable tolerance type then may be possible to select.

I'm not sure - because you use Creo 4.0 (I'm on Creo 2.0), and also I'm guessing from your screenshot: but you seem to be loading the tolerance tables into the drawing?  And the dimensions you are concerned with - are they "shown" dimensions, or are they drawing annotations?

In other words, is the dimension you are trying to change named d1 or add1?

If it's "add1", then it should work.  If it is a "d1", then you need to load the hole tables into the model and assign the fits to the model dimensions.

Hi There, I've been having the same problem today. Eventually managed to work it out though.

I added the following config options.

tol_display = yes

tolerance_class = medium

tolerance table_dir = 'you'll need to work this out for yourself' (creo install directory probably) look for *.ttl* files

Then in the model I had to load the tolerance tables.

in the model go to..

File\prepare\model properties

in features and geometry there is tolerance

change (you may need to change std too)

tol tables

retrieve

select all in the list which should come from the location above (use shift key to select all in one go)

You should now be able to select plus/minus and then the box will give you options general\broken edge\shaft\hole from there you can select H6 or whatever you need.

k finding a reliable supplier in China. It can be very difficult. I just had some aluminum prototypes made by a company I found on Alibaba and the tolerances were not even close to being correct. I was very specific and clear about the tolerances that I wanted and how the parts should fit together. However, when the parts arrived they would not fit together and were all about +/- 0.5mm or worse. I am sure there are better suppliers out there, just be skeptical of anything they tell you.
