Hi @trrnnm03e23h ,

Please specify your AutoCAD version and macOS version installed on your Mac.

Please provide more details about print process:

- Do you use Plot Styles to set line thickness (lineweight) when you print your drawing?

- Do you set lineweights byLayer or assign them individually to the objects in the drawing?

- Do you print directly from AutoCAD or save PDF at first?

- What printer do you use when you print from AutoCAD?

Can you share the drawing where you have this problem with lineweights?
