A PDF document can have many pages and each page can have many layers. Users now have access to the available layers by opening the Layers Display dialog through one of the following paths:

• By right-clicking on the PDF files in the Raster manager dialog and selecting the Layers.
• By selecting the Layers field in the Display Print section of the Properties dialog.

Select the desired layers in the Layers Display dialog and click Apply, then OK to update the view in ProStructures.

If the same PDF page is attached more than once, each attachment can display different layers. To achieve this, some information are stored with the attachment to know which layer(s) must display for each attachment. To minimize the risk of being out of sync, Raster Manager stores only the layers whose display status has changed.
