If the polylines have diferent Z values you'll need to Flatten them first (Command: Flatten) before using the polyline comand to join them together again.
Note if they are 3D Polylines you'll need to explode them before converting them into polylines and finally joining them together again

Strange, I've been using Flatten since 2004 and I am still using it on 2010.
Which version of AutoCAD 2009 are you using. Is it autoCAD lite? perhaps this is the problem. You get what you pay for unfortunately.
If you can't flatten then 1 way I can think of is using quick select (top right hand corner of the properties bar). Select all polylines (you can do this by layer too to filter out all unwanted layers), set elevation to zero & then you can join.

It means that all Polylines should have on 0-elevation then we can join them otherwise line having different elevation and different UCS plans can not be joined......... |

To the best of my knowledge no you can't join Polylines in different plains without making them co-plainer 1st. this is for good reason as the lines in reality are not connected. There must be a link connecting them together (i.e. a 3D Polyline).
Unfortunately you can't join 3D polylines to regular Polylines. 1 must be converted into the other before you can join. I've never converted a 2D polyline into 3D. Perhaps someone else out there knows how if it is at all possible without having to redraw or trace.

Gullgee never answered the question of what version he was using. If he's using Autocad LT then the lisp routine will not work for him. If he's using the full version, then he needs to load the Express Tools in order to use the Flatten command. ------------- Online Portfolio: http://www.rdeweese.com/" rel="nofollow - http://www.rdeweese.com/ |

Actually I have drawn 6KM of length of 108" dia pipeline centerline, which having different elevations and ucs plan. i trying to make it one joined polyline. I think it will be helpfull for me.Thanks every body for giving the right way
