Setup an ISO-standard Model in Drawing Mode

gstall — Thu, 17 Apr 2025 12:38:19 GMT

Hello,

When creating a drawing using a format file, Creo automatically select the ANSI/ASME tolerancing standard and I need to manually change in order to have setup the tolerances as DIN/ISO.

Is there any way we can (via a config parameter, dtl file, format file, etc) to setup the drawing to follow the ISO standard?

Thank you!

You need to use the .iso.dtl file. If you create a drawing template for ISO then it will be set by default when you use the template. If you assign the .iso.dtl to the template and save it then you should be good to go. See the link below.

•iso.dtl ISO (International Organization for Standardization)

•jis.dtl JIS (Japanese Institute of Standards)

•din.dtl DIN (Deutsches Institut für Normung / German Institute for Standardization)

The Detail options settings is saved with each individual drawing file.

Thank you for your reply. I know that this is possible to edit and setup when working with templates, but in my company we work with formats instead as they happen to be more flexible for our needs.

I've loaded the ISO.dtl as drawing and format setup file but when creating a new drawing I still have the ANSI/ASME instead of the ISO.

I've tried to edit this parameter in the format but I cannot define the tolerance standard in the .frm

You can also set the .dtl file for a format and save the format for re-use. Check the below config options to see if they are set in your environment.

if you create a new format then Creo uses dtl file mentioned in FORMAT_SETUP_FILE config.pro option
if you create a new drawing then Creo uses dtl file mentioned in DRAWING_SETUP_FILE config.pro option

If you need to use a format and you want it to be set up for ISO standards, then create the format using the .iso.dtl file and save it for reuse. If you want newly created formats and drawings to use ISO then use the above config options to specify which setup file to use.

Hello,

I've tried adding the iso.dtl as both format and drawing setup file, creating then a new format and then a drawing using the format but I still have the same issue. The in the Prepare section of the drawing I still have the ANSI/ASME tolerances instead of the DIN/ISO.

I've opened the trail file when I update the tolerance standard to ISO and this is what I see

~ Command `ProCmdDwgProperties` ~ Activate `mdlprops_dlg` `TOLERANCE_lay_Controls.push_Change.lay_instance` #STANDARD #ISO/DIN !%CILoading 2 tolerance tables ... !%CPDimension tolerances changed. Regeneration recommended. Regenerate? [Yes] YES! !%CIModel tolerance standard set to ISO/DIN. #DONE/RETURN

I've tried to look for any parameter in the config similar to "TOLERANCE_lay_Controls.push_Change.lay_instance" but I've not found anything useful.

That excerpt from the trail file indicates that the model tolerance standard was changed to ISO. The drawing/format standard is probably still set to ANSI/ASME. There are separate controls for a model and drawings for tolerance set up.

Open the format that you want to use and attempt to change the tol standard to ISO. Open the detail options file from within drawing mode, are you able to change this setting to ISO here? IF you are able to change this to the desired setting then you need to save the format for reuse.

I think that this may be linked to an environment variable that I do not control and will not be able to me modified. I've changed all the different config and dtl parameters with no luck.

Thank you anyway for your support and patience 🙂
