Cannot add fit type tolerance in the drawing (ex H7)

[MG_10529190]

Hi!

I have problem in my creo version 8. I cannot add H7 tolerances do some drawings. For some I can, for others I just can't see the option to do it.

I tried to change settings of models, add tables with Hole tolerances etc. Nothing seems to work. Does anyone have any ideas?

I am attaching 2 examples - one is a drawing where it works, other where it does not.

You need to add the tolerance look up tables to your Creo model. They are not loaded by default.

Follow the instructions here and report back:

Thank you, I already tried that. It does not work. I have just repeated all of those steps. Attaching snips.

That looks like a sheet metal part in your picture. Is this an issue in only sheet metal parts?

[MG_10529190]

Yes, but the other one, where the H tolerance works is also a sheetmetal part.

Are the features you are tolerancing hole features in both models? If they are, were the holes created the same way in both models?

As a test: Try copying (copy-> paste Special) the hole feature that works into the model where it is not and see if you can apply the tolerances.

No, they are simple extruded cuts, but again, on the other model with extruded cut, H15 works. Also, I added a normal hole feature to the one where it does not work, and still, can't add the H class tol.

Understood. Is the issue unique to this one model or are you able to reproduce it on other models? If it is reproducible, I would open a call with tech support on this one.

I am out of ideas on this at the moment. 

Are you able to upload these models? It may help someone here figure out the issue. If you do, note the Creo release you are using.

If you are not able to post these models, make a test model with the problem and post it here.

Unfortunately company policy prevents me from uploading any models at all.

Also, this occurs in about 40-50% of the models and I can not see any similarities between the groups.

Ok, was able to solve this.

It seems that the steps from your first post need to be done, but for both model and the drawing. Then it works. Only model is not enough. Thank you!
