PDF is a vector image format popularised by Adobe Acrobat. Many print shops will prefer PDF format if you want to print the 
Floor Plan, 
Table Chart , 
Guest Chart or 
Stationery pane to poster size. For example, to export the Floor Plan pane as a PDF:
1.Select File>Export, the 
Export window will appear.
2.Select floor plan to PDF/PNG/JPG/WEBP/BMP image file.
3.Click OK, the Export Floor Plan window will appear.
4.Select the file type as PDF, choose a file name and location and click Save, the Export PDF window will appear.
5.Select the appropriate Size and Orientation for the PDF and click OK.
If you have problems with built-in PDF export you can also export PDFs indirectly, as described below.
