Yes, you can export the entire assembly diagram in Workday Studio as a PDF. Refer below steps :

1. Open the Assembly in Workday Studio: Go to your studio project within Workday Studio and open the assembly diagram you want to export.
2. Select the Print Option: In the assembly menu, click on Print Diagram. This will open up the print options for your assembly.
3. Choose PDF as Your Output Format: When the print dialog appears, select a Microsoft Print to PDF option and click on Print. Most systems have a "Save as PDF" option in the print menu.
4. Save the File: Locate destination folder you want to save PDF and click on Save.

The steps above are demonstrated on a Windows computer, but they should provide enough guidance to save the PDF on other operating systems as well.
