I am an AutoCad ninkompoo (dummy), and I have an existing drawing that has 2 layers of lines. I wish set it that layer1 lines have a thickness of 0.5 units while layer2 lines have thickness of, say .25. I have experimented with settings in the Format/Layers dialog, but at the end, after entering, what seems to be, logical settings and OKing the dialog, all the lines are of same weight. And even after plotting to several formats and viewing, the story is the same. Is there any way to achieve the objective of letting prints and display show the desired output? Thanks for any input - no pun intended
