Hi @carl.harris.97,

Since you are doing this in AutoCAD for Mac, this will be slightly different than in Windows.

I find the easiest was to do this is to create a Custom paper size and set the margins to 0 mm or 0 in.

I made a quick video that shows this process. I open the Plot window and assign a printer (AutoCAD PDF) and then create a Custom A3 paper size no margins. This is called Full Bleed.
