explode a pline.... sort of...

I'd like to explode a multi segment pline so that none of the segments are joined but the segements still remain plines, rather than converting to lines. Is this possible? Thanks.

 

You don't need a program for this, just follow this simple macro:

1. explode the polyline

2. use the command MPEDIT --[ and use the Previous selection]

Select objects: p
4 found

Select objects:

Convert Lines and Arcs to polylines? [Yes/No] <Yes>:

Enter an option [Open/Close/Join/Width/Fit/Spline/Decurve/Ltype gen/eXit]
<eXit>:

 

thanks guys!

 

Explode -> pedit - multiple - previous - yes - enter - enter

Here's a little thing that breaks your LWPOLYLINE without losing width data on the segments.

[pre]; PLBUST breaks an LWPOLYLINE into individual LWPOLYLINE
; segments without destroying width data.

(defun-q CLBUST( / oldcmd ename edata vcount )
(setq oldcmd (getvar "cmdecho"))
(setvar "cmdecho" 1)
(if (setq ename (entsel "\nSelect LWPOLYLINE: "))
(if (= "LWPOLYLINE" (cdr (assoc 0 (setq edata (entget (setq ename (car ename)))))))
(progn
(setq vcount -1)
(while (assoc 10 edata)
(setq edata (cdr (member (assoc 10 edata) edata)) vcount (1+ vcount))
)
(princ (strcat "\nBreaking LWPOLYLINE into " (itoa vcount) " separate LWPOLYLINES..."))
(command "pedit" ename)
(while (> (setq vcount (1- vcount)) 0)
(command "e")
(repeat vcount (command "n"))
(command "b" "g" "x")
)
(command "")
(princ "done!")
)
(princ "\nEntity selected is not an LWPOLYLINE. ")
)
(princ "\nNo entity selected. ")
)
(setvar "cmdecho" 0)
(prin1)
)[/pre]

Unfortunately deleting the first post will remove the second one
since it answers the first. Let's leave it since you corrected
with your second post.
