I'm not sure to understand your problem completely. Please explain more detailed. Do you want to set line properties for drawing new lines, or do you want to change existing lines? What means "it's the same for all layers"? Do the lines seem to look the same although you have set them differently?
Before drawing a line you set the properties in the line attributes tab. You can choose a certain type, or say "By Layer", then the value set in the layer attributes is valid.

"How to recap an ad on my mailbox when someone answered." Sorry I don't get what you mean. Maybe because English is not my native tongue.

You should study the manuals. Now you get there via Help - Online. At least it works now on LC 2.1.3. Or go to the WIKI.
