Storm Pipe Lisp Command

Hi,

I was wondering if someone could help me out with the attached lisp file. My company likes to show the storm drain in our base with 4 different lines. One line for the centerline with a global width of zero with linetype continuous that would be on layer A, a polyline for the centerline with a global width of whatever size the pipe is with dashed2 linetype on layer B. The other two lines will offset half the distance of the pipe size from the centerline and will be continuous on layer B. The way the lisp currently works is it Converts selection set of Lines, Polylines, LWPolylines, and Arcs to sets of triple parallel polylines. Outer polylines have zero width and CONTINUOUS line type, while inner polyline uses Dashed2 linetype with user-selected width. I would like it for it does not change the original line i drew but instead copies and changes it to whatever my current layer is and offset it half the size of the pipe to both sides and than changes it to to a polyline with the global width of the pipe size and dashed2. I would appreciate any help.

To help clarify on what it looks like, I attached a PDF of it.

it seems to work maybe something wrong in the linetype scaling, also linetype use this, you need to look at the sequence of events in your code before changing the line type make a copy of it and move it slightly away do the edits then move it back
