Lineweight post processing in illustrator?

[john2]

does anyone uses here illustrator for post processing of sketchup hybrid outputs [textures with vector line]. i wanted to know the workflow and tips and tricks. , best format i.e. pdf or eps. i don't want to learn layout, as i'm used to indesign and illustrator for making drawings, editing and presentation work. i want to edit lineweights in illustrator so that the objects neart to the viewer's eye have more lineweight and the ones farther away have less lineweights. and i want crispy vector outputs , no fog effect.
