DWF in viewport doesn't print

[CADmgrMike]

I have a drawing with a clipped viewport that displays a DWF file.

If I print using the AutoCAD PDF driver, the DWF file shows in print preview, but doesn't show in final PDF output.

If I print using an Acroplot PDF driver, everything prints fine.

Ideas?

Looks like youre facing an old CAD problem. Please, try PROXYSHOW and choose the value to 1

Controls the display of proxy objects in a drawing and 1 if for display all graphic images

I figured it out and forgot to post here. It's the pc3 file.

If you set the pc3 file to 400dpi for vector quality, the clipped viewport displaying the DWF will print.

Anything above 400dpi and it won't print.
