transparent background grayed out

[Dave Brach]

I would like a pdf in a plan view to have an opaque background.  When I drag the pdf into a plan view it has transparent background, when I drag it into a layout it is opaque.  In both instances the "transparent background" checkbox is grayed out.

Operating system used: Mac Apple Silicon Sequoia 15.6.1

Does the PDF actually contain transparency? Not sure why it would present differently in your two cases...

It's not just this pdf.  I have tried many pdf files and they all do the same thing:  transparent background when added to a view, opaque background when added to a layout, "Transparent Background" button grayed out.  Any random pdf, same thing.  What does it do for you?

Ok, I just realized that I can use display order to correct this.  Duh.  But one thing does not respond to display order: the titles of drawings on a layout: there is no way to send those to back?

We generally only use PDFs for reference or stitch them directly into the end document... so I am not sure about the interaction...

When you place a PDF as a drawing, you have no choice for the transparent background.

This option is only active when you are placing a view as a drawing on a layout.
