I know that Solidworks is not  AutoCAD, but I was wondering if I could use the layers functionality of Solidworks to work like AutoCAD.

I am trying to make it so that each layer has a different thickness.  I am able to change the thickness in the Layer properties, but the lines do not change in thickness.  Here is an interesting thing though:  When I just sketch a line, it has all the properties of the layer that I want.  I have come up with a few solutions to this problem, but they all require too many mouse-clicks.

In summation, does anyone know how to change the line thickness of only certain lines of a drawing while also having the functionality of the layers?
