Question

how to change default tolerance value in drawing

Hello,

 

just wondering how the default tolerance value works at new created dimension in drawing. Since i use mostly the +- symetric - would it be possible to set the default tolerance (maybe in drawing setup file) value this way?

 

Thanks in advance

You can set this in config.pro. It seems to be very convoluted but once set, it works.

For some reason, it has to be in config.pro, and not changed in the options editor.

The values are set to a factor of 1000x. Drawings take on whatever the current config.pro settings are.

These are the valid options in config.pro (linear and angular):

I used whole numbers in the settings in config.pro. These are the default ones that show up on the screen.

If the current default_dec_places is 3, the .008 will be used on drawing dimensions as well.

If, like me, you use default decimal places is 4, I cannot seem to get these to be recognized by default. I suppose I need to file yet another support case. Config.pro is recognizing the linear_tol_0.0000 50 but the actual value comes in at .0001 in both drawings and models.

I created a case for using values greater than 9 in these default toerlance settings. Options shows it is accepted but in reality, it doesn't work.

Use case, my drawings use 3 digit dimesnions but I want to see 4 digits when modeling. I want the default tolerance value to be .005(0)". I can't do that with 4 digit dimensions!

Support in this case is becoming very frustrating. I am being told that indeed you cannot apply a value greater than 9 (DUH!). I did not hear that this is functioning according to specifications.

Support also came up with the fact that linear_tol is a valid option although it does not show up in the options>find dialog. Support said they will file the SPR for the missing option.

I see this being escalated! There is no reason the option linear_tol_0.0000 cannot accept .0050 as a value. Even the dialog is accepting it in options. But it is not being carried forward to newly created dimensions.

I even asked specifically if the linear_tol (and angular_tol) were WF/Pro-E options that were being replaced with no answer. I only received the link to the options guide that still includes the two in Creo 2.0.

Hi Tomas,

You didn't say if you were working in Imperial or Metric. Seems the discussion so far has been about Imperial (inch based) figures.

If you work in metric you can set the config

tolerance_standard ISO/DIN and this allws you to select

tolerance_standard medium (or fine or coarse) and these work according to length not the number of decimal places.

There is also as setting under TOL SETUP for Tol Tables so maybe it is possible to have some sort of general rule under that. Have never tried it as have always used metric tolerancing system though apparently this uses a set of ISO/DIN tolerance tables

Regards, Brent
