No matter how many setting I play with now, I can't create a pdf. My pdf software has not changed.

I only mentioned the Acrobat software to say that hasn't changed from when I previously was able to create a custom paper size plot. .&nbsp;&nbsp;</P> Wed, 17 Aug 2022 14:46:26 GMT https://forums.autodesk.com/t5/autocad-lt-forum/large-format-pdf-creation/m-p/11364750#M9887 mattgsoUK48J 2022-08-17T14:46:26Z https://forums.autodesk.com/t5/autocad-lt-forum/large-format-pdf-creation/m-p/11364790#M9888 Custom-sized sheet sizes are easiest/best created in the printer driver (in this case your Acrobat software), is that not where you do it? here is how for Acrobat drivers <A href="https://acrobatusers.com/tutorials/how-to-create-a-custom-page-size/#:~:text=On%20Windows%2C%20from%20an%20open,height%2C%20and%20unit%20of%20measurement" target="_blank">https://acrobatusers.com/tutorials/how-to-create-a-custom-page-size/#:~:text=On%20Windows%2C%20from%20an%20open,height%2C%20and%20unit%20of%20measurement</A>.<BR /><BR />If nothing changed, then in previous LT versions did you save then use a custom PC3 file?
