sketched dashed lines in drawings

I did this before and can't figure out how to do this is now.  I want to sketch lines in a drawing that are dashed style.  When I go to the previous drawings I've done it in I can't find anything showing how.  It's not in properties when I click on the line, and I haven't had luck following the directions in the help file.  I've searched for the .sldlin file and couldn't find it.  Can any one help me?

Thanks,

Rob
