"I can retrieve a parameter from the cadDocument and add it to the name of the published PDF using the publish.afterloadermethod as shown in the link below. For example, the stock number parameter. However, this parameter is empty for drawings. Therefore, I am thinking of pulling this parameter from the associated WTPart so that it appears in the name of the published output for all CAD documents. Can you support me in this? Is this possible, or is there another method you would suggest?"
