Copy along a P-Line path

[Rhayes]

Is there a way to copy an object along a p-line path.???

[lpseifert]

Make the object a block, then use the Measure (or Divide) command with the block option.

[Rhayes]

Thanks. I did that. However I want to have my block spaced out exactly 1' apart.??? How do I do that.???

[rustysilo]

Use MEASURE

[Rhayes]

THAT'S IT...

Thanks...

how i could copy object along p line with uneven distance?

how i could copy object along p line with uneven distance?

 

search on-line for PUT.LSP

[rustysilo]

Someone, I think lpseifert, posted one here some time ago called measureplinepts.lsp, but it might take some searching.

Here's one similar to the one Rusty referred to. You could modify it to insert blocks instead of points.

;places point at specified station along a polyline, measured from start LPS 2008

(defun c:pop ()
(vl-load-com)
(setq oldosnap (getvar "osmode"))
(setvar "osmode" 0)
(command "ucs" "w")
(if (/= (getvar "pdmode") 3)(setvar "pdmode" 3))
(setq ob (entsel "Select curve: "))
(setq p2 (getreal "\n Specify Distance : "))
(setq obj (vlax-ename->vla-object (car ob)))
(setq pt1 (vlax-curve-getPointAtDist Obj p2))
(command "Point" pt1)
(command "ucs" "p")
(setvar "osmode" oldosnap)
(princ)
)

>>edit

never mind, here is the PUT.lsp, seems to be what you want

you guys awsome thx a lot.

Here is some code for inserting blocks along a pline based on number required per segment rather than distance. Also rotates block you may want to remove that part. Block name is holden

 

A good oppurtunity to say thanks for others helping me with this code.
