Question
QUESTION: I do a lot fo electrical wiring and several years ago I seen a drawing that I "think" used a Multi color Dashed Line (possibly a PLINE) to show stripped wire.  IE  Red wire with a Black strip.  I lost the file in a computer crash and never was able to determine how it was done. How do you think this was done?

ANSWER: The one idea that pops into mind would be to draw a solid black line, then a dashed red line right on top of it.  Make sure you select the red line and change the draw order to put it on top.  It might take some tweeking on your plotter settings to make this work.

Another way would be to use two different dashed lines, one having a double length space to start with, the other having a single.  That will take a little time to create as well.  

Basically, not really an easy way to do it.  I'd think once you figured out the linetype settings, you might be able to create a lisp routine to draw both lines at the same time.

Hope that helps.

QUESTION: I started to recall last nite.  It used (2) different "dash" lines that overlayed.  Trouble is that the first command in a kine defination has to be a dash and I need a defination of a space then dash to oppose the dashed line def.

Answer
You might try making the first part a dot instead of a line.   Then a line from there on.  I haven't worked with linetypes in years.  Without digging into my linetypes, that would be the best thing to try.  Take a look at a dot/dash linetype and start with that.  

Hope that helps.
