Linetype scale in SW?

Hello;

       I'm wondering how, or if there's a way to control the line size and gap for mainly hidden lines in model space. My lines appear more like dots, the hidden lines don't look right. I don't know if this is something that you can adjust or not, but I haven't found it yet.

           Thks, for any help in advance;
