Windchill CAD Worker Issue - Font not reproduced during publishing

Version: Windchill 13.0

 

Use Case: A CAD model includes a feature whose geometry is generated from a text string that uses a particular font. Since the font isn’t installed on the CAD Worker machine, the worker silently replaces it with another font, giving an incorrect representation without any error notification.


Description:

Hi everyone,


I’m running into an unexpected behavior with the Windchill CAD Worker when publishing Creo Parametric models that contain text using a non-standard font. In our case, the model includes a feature whose geometry is generated from a text string that specifically uses this font. Since the font isn’t installed on the CAD Worker machine, the worker silently replaces it with another font. The publish job finishes successfully, but the resulting representation is incorrect and doesn’t match the original model.

 

What’s most concerning is that the issue isn’t clearly reported anywhere. The only trace is a single warning line in the trail file, but no error is raised, no notification is sent, and the publishing task appears to complete normally. As a result, incorrect published content can be generated without anyone realizing it.

 

We’re aware that the simplest fix this would be to install the missing font on the CAD Worker machine, but our IT department doesn’t allow this due to legal and cost-related restrictions, so that option is off the table.

 

I’d like to know if there’s any way to make the CAD Worker treat missing fonts as a real publishing error, or at least to surface the issue more clearly, maybe through some form of notification.

 

Any suggestions or experiences would be greatly appreciated: maybe someone has already run into the same problem. A colleague of mine also asked a similar question in the feedback section of a PTC Support article, but we haven’t received any answer yet.

 

A couple of boring details about our setup, just in case they matter: Windchill 13.0, Creo Parametric 10.0, Creo View Adapter 11.1.

 

Thanks!

Last night, I received a reply to my comment on the article I mentioned above.

 

The technician's recommendation is to open a support ticket.

 

In the meantime, we tried using Model Check, which is a new tool for us, to intercept the font error, and we succeeded.

 

Today, we will try to see if we can also cause the publication to fail.

It is critical that the CAD worker machines reflect the configurations of the end-user's machines.  It's not realistic to expect publishing to match if not configured the same way.  If that is not an option, then it is possible for end-users to manually generate the visualization data as part of their save and check-in, but this will be missing other additional files that the workers may be configured to generate.  The Creo View Adapters are simply using the CAD software (Creo in this case) to do the publishing.  If the CAD software doesn't throw a fit about the issue (missing font), then I don't think the CAD worker process is going to even notice.  Your best course of action is probably to open a support case with PTC and ask them directly.

    Agreed with @TomU . If this is branded font for your products, that should be justification for IT to allow the font to be installed. What kind of costs are we talking about here? I also cannot legal concerns as this seems to be legitamate use of the font. Did the designer who added the font go rogue and they should have used a standard font? Short of that, I would suggest the Windchill ideas board to submit something but honestly, I think it will be given a low priority.

    The font was chosen by our marketing department to reproduce the code of our finished product on the molded parts.

     

    The cost of the font used by dozens of users is very low, while the license to use it on the worker would cost tens of thousands of euros, so we are currently looking for a way to intercept the problem before spending a substantial amount of money.

    Seems like someone needs to have a chat with marketing.  😉

     

    If the CAD worker is running under a single user account, does the font really need 'server level' licensing?
