How To Create A Blank Line Type?

[Anonymous]

Hi,
How can I create a Blank Line Type, so I can use it for example in wood member objects that show the center line of the joists/beams. These center lines are making the drawings too messy. There are no options to turn them off. Anyway this is a nice line type to have for many other tools, to hide unwanted graphical representations.
Thanks,
Joseph

why don't yo use a solid line with pen 91 (pure white)?

Granted, that would work when ther is a separate option for pen color. Not all object lines have independent pen color option!
Thanks,
