Issues saving drawing from layout (Mac OS)

Hi everyone

I was wondering if anyone can advise on this.

I have scaled my drawing in layout and would like to save it as a pdf. However the preview of the file is blank ? So whenever I save it, it just saves as a blank pdf

Any thoughts on how to resolve this issue ?

While the Layout is current (not in an active Detail), type the SetDisplayMode command.
Is it set to Wireframe?

If not, that’s the problem.
Set it to Wireframe.

If that’s not it, we will need the 3dm file.

Thank you ! This solved the problem
