You can set a preference to specify whether to automatically download secondary content for different types of files. The secondary content categories for your site are listed in Windchill by selecting Preference Management > Operation > CAD Data Management > Content Handling > Download. For each category of file type, setting the download preference to Yes (the default is No) means that on downloading a Dynamic Document, any secondary content of the specified category type is downloaded automatically along with the primary content. Setting the value to No specifies that the secondary content is not downloaded automatically with the primary content of dynamic document.
