PDF Line Thickness

Hi,

I`m facing problem when saving as pdf where the line are too thick and i need to disable line weights to properly view my drawing on adobe pdf. This does not happen when i`m using autocad to save my drawings. Example is as below (1.solidwork 2.autocad) The line and size is the same and they are both saved in A3 formats pdf. How can i fix this?
