How to set the line thickness of the model views in the drawings

Currently all lines of the views in the drawings are the same, and only get to their required state (thickness) during export, when pen tables control how thick the lines are.

I would like to remove the use of pen tables and start seeing actual thicknesses on the screen during development of the drawings. I tried playing with line thicknesses in line styles and I think I could make it work. But I only managed to change the line thickness for existing views, however any new model views still default to thin lines, regardless what I set as default line style.

I might be using that default line style functionality wrongly because no matter what I do with it it doesn't seem to change anything. 

Is there a way to set the styles of the lines for new views in the drawings? I would like to set the model edges to be slightly thicker than surfaces (quilts) of cosmetic threads and crosshatches in cross-sections. 

I am on Creo 9. Many thanks for the help.
