I'm looking for a way to change the default tolerances when exporting an STL file (triangle tolerance and adjacency tolerance). I looked through the customer defaults and part preferences, but didn't find anything obvious. Is there a setting that controls these tolerance values? If so, where is it?
@cowski1 Check this article on the Knowledge Bases that i have made.
The only thing that i experience is that you can set the defaults but the export still comes op with the ootb default of the angular Tolerance.
Also i don't know why siemens has the 18 degree angulare tolerence default on because you can see it in your print that the round shape is facetted.
I have just test some things.
The angular tolerance looks that it doesn't do much.
When changing the chordal tolerenance you see the same thing changing in your export as by using the traingle tolerance in the NX10 export dialog.
I should mention that I'm still currently using NX 9, so I'm looking at the "old tolerances" as mentioned by @Cesare. The tolerances seem to be part specific; if I change the value and perform an export, the same values will be used for the next export. I can't find a setting to control the initial default value. I guess that I'll need to update the template files to use the new value and hope the users make the proper change when exporting out an exisiting model.
looks like there is an PR for this behaviour:9047785

Steps: - Go to Customer Defaults > Gateway > Translators > STL-Export - Set Angle Tolerance from 18 to 1.0 degrees - Restart NX - Open or create a new part - Start File > Export > STL -> the angle tolerance is correctly set to 1.0 degrees - Selected a body and press "Apply" or "OK" -> the angle tolerance now is 18 instead of 1 degree. All other settings (such as side tolerance) remain the same as set in the customer defaults - Reset button in the stl export dialog box or restart NX call back the predefined value Movie uploaded to show this behaviour.
There is also an setting issue when uniting Solid bodies with convergent bodies.
If you have a cylindrical face it gets a very big angular tolerance when uniting to a convergent body.
