Question

Removing General Linear Tolerances Without Affecting Local Feature Tolerances

Hi everyone,

 

I’m working with the team in charge to move to MBE, and I’ve run into a challenge I hope someone can help with.


I’m trying to remove the general linear tolerances that appear on every part (see attachment 1). I experimented with setting the "tol_Display" option to "no", which does remove the general tolerances, but unfortunately, it also hides all the local tolerances on features of size (see attachment 2 and 3).


Has anyone found a way to remove just the general linear tolerances while keeping the local ones visible?
I’ve attached a reference image to show what I’m working with. Any tips, workarounds, or settings I might have missed would be greatly appreciated!


Thanks in advance!

The tol_display config option has three possible settings: no, yes, and no_tol_tables. You might want to try the last one.

I did, but the result it's the same, both tolerances, local and general, are gone.

Set config option tolerance_standard to iso

For existing models and model templates set

File > Prepare > Model Properties > Tolerancing Standard > Standard > ISO/DIN

Hello,
I tried the option you mentioned, and it successfully achieves the intended result (see attachment). However, since we are currently working on the project to transition our company to a Model-Based Enterprise (MBE), we primarily use models based on the ASME standard, though we also incorporate models aligned with ISO GPS. As part of this initiative, it is a requirement to manage the dimensioning and tolerancing system also represented within the 3D model. Therefore, this solution would conflict with that requirement.

File > Prepare > [Detailing Section] Detail Options - CHANGE:
default_tolerance_mode: nominal

 

This will set the default tolerance to nominal, so when you place the dimensions, they will have no tolerance by default:

Only after you've changed it to, say plus-minus, the tolerance will appear. You can then select your tolerance table or set manual tolerance values:

Hope this is what you are looking for. If so, you can apply this setting in your speciffic template file - you can then select if for specific purpose only.

From the dimensions, I guess that you are using a Metric system for Dimensioning. If so, are you using ISO standards for General Tolerances? The general tolerances shown in pic [1] appears only when set to ANSI Standard.

 

You need to set the Tolerance Standard to ISO for it to disappear. Refer picture below.
