Foly line

Is it possible to make the line as in the attachment with Multi line tool?

Or is there a other way?

if using C3D, and this is supposed to be a pipe, then C3D styles can handle that fairly well.

if just using as vanilla acad to get a line, then I would lay in a centerline using PLINE where needed, offset both sides, and then Pedit the width if the original ot twice the offset distance. you end up with three objects, instead of a single line.

Is there a lisp routine that can do this?

"Youre drawings are as good as the symbols that compleet them....."

Actually, symbols do not make a good drawing. They can help but they are far from THE determining factor. I've always said that symbols don't matter. Just have a look at the variety of ways the same design can be presented.

Grammar and spelling are much more important.

In simplest terms, try this. It assumes you start with a Polyline that has the desired non-continuous linetype and linetype scale.

(defun C:PPWE ; = Polyline Path Width with Edges (/ path pathobj wid) (setq path (car (entsel "\nPolyline path object to give width and edges: ")) pathobj (vlax-ename->vla-object path) wid (getdist "\nWidth: ") ); setq (vla-put-constantwidth pathobj 0.0) (vla-offset pathobj (/ wid 2)) (vla-put-linetype (vlax-ename->vla-object (entlast)) "Continuous") (vla-offset pathobj (- (/ wid 2))) (vla-put-linetype (vlax-ename->vla-object (entlast)) "Continuous") (vla-put-constantwidth pathobj wid) (princ) ); defun

This is what it does with something of HIDDEN linetype:

For your original drawing's configuration, you will need a linetype with dashes and gaps of equal length. There's one called EVENDASH that I'm not sure comes with plain AutoCAD but I think may have come with Architectural Desktop years ago -- if you don't have that, it's easy to make one.

It can be given all the usual enhancements -- verify that you selected a Polyline, and that it's not currently of Continuous linetype, remember your Width value to offer as default, *error* handling, Undo begin/end wrapping, etc.
