Merge closed polylines

[VaKaDi]

Hello all,
every time i use Autocad i realize how few i know about it...
There are so many things it can do that i do not know (yet anyway).
The latest problem i came across was trying to merge 2 closed polylines. That is i have 2 closed polylines having at least 2 same points with each other. I want to merge those 2 to become 1 or better yet create a new polyline containing both. I can not do it through PEDIT -> Multiple.
I guess there must be a way to do so but i do not know it...
Thanks in advance for any reply!

PS: I have searched for this question in the forum and found no answers to that problem! I am sorry if such a thread already exists!

I don't believe there is a native AutoCAD function that will merge two closed polylines. However, you might want to take a look at a program called PolyTools 2.0 that advertises itself as a collection of polyline editing tools for AutoCAD. One of those tools is a routine for merging two polylines (supposedly with one click). It retails for $100 (US) but there is a free 30-day trial available at:

Thank you for the reply. Actually i had searched internet and found that collection. Haven't still tried it though! But i still believe there must be another way to do this through autocad, for example with BOUNDARY command (only that output would be 1 polyline).
Thank you for the help... I will try that collection and see. Problem is it is not free!

You can change status of closed polylines to open via properties tab; alternatively you can 'break' each polyline at the required vertex using "pedit", then "edit vertex", then "break".

You can then rejoin the polylines as you wish.

This was the way i do it... But i came across with needing to merge more polylines and also do it faster (time=money)...
But still Thanks for the help!

The method proposed by Doove is one I've used myself but a true "merge" option in the polyline edit toolset would be a welcomed addition. I could see a good use for it in architectural drawings working with walls.

Draw a big rectangle to enclose the two polylines. Use the BPOLY command and select a point inside the rectangle but outside the polylines. The command will create two new polylines: une superposed with the rectangle and one more that suit your needs. Just delete the initial polylines and the rectangles.
