line styles

Hi Michael,

I was wondering if there was a script or a way to change line style into say a dashed style (sort of like the same as construction lines).

Right now, i can change the colors and lock lines/curves that I use as guides, but it would be easier on the eyes if the style could be modified, e.g. dashing, opacity, etc. Is that possible at all?

Thanxs,

Luis
