wrap object as a polyline

Hi Folks,

I am looking to see if there is a lisp routine other than wrap object that I can use.

I have multiple polylines (such as a path of stepping stones) that are not grouped. I would like to create a single polyline that follows the edges of the whole set of individual polylines in one large polyline.

I tried the lisp wrap object, but it justs creates a second polyline around each of the individual stepping stones instead around the whole path of stepping stones.

I tried grouping them, but that didn't work either. I tried to create a block, and that didnt work either.

Is there something I can try???

I found this in my archives, I can't even remember trying it; maybe it will work for you. Use at your own risk...

I do recall that LDD had a 'Shrinkwrap' routine, if you have access to it.

Shrinkwrap.lsp

ok - so I tried both of these lisp routines and they still don't work.

It works if the polylines are intersecting each other, but not if they are separated. I have tried to block them, but the lisp routine still doesn't work.

Here is what I am trying to accomplish in visual aid in the jpg.

Hope we can figure this out.

The Lsp Working Good Except when select the object and Enter it's back to the previous Zoom

I did get shrinkwrap to work by offseting the objects a few times with a known distance till they crossed then ran shrinkwrap and kept the outer pline and offsetted that back to original. Dont guarantee it will work every time.

Look at the other post here about wrapping blocks it is the same type of thing.
