Hi

I'm trying to print my ducting drawing to PDF and when I see a preview it shows ducting below other ducting as hidden as in real life. When I print to PDF, it shows all the ducting in wire frame. Does anyone know how to print showing objects below other objects, as hidden. Please see attachment.

Thanks

In the Plot dialog, expand the right half (see round button with ">" symbol at bottom left.  In the additional half of the Plot dialog, set the "Shademode" to either "As Displayed," or use 2D Wireframe.  The 2D Wireframe is the only visual style that works with the MEP Displays to add the hidden lines.
