Just tried your code. looks promising as well. I will test this on various drawings. thank you.

@Sandeep RC This shouldn't be a problem because the code is not based on the offset of the lines but on the connection points that may exist between the polylines.
If that doesn't work well, I suggest changing the value of the "dfzz" variable; (setq dfzz 1E-08) in the code.
Indeed if for example you are working with large coordinates, it may be useful to lower this value to 1E-06? or less...

@Tsuky Okay and thanks once again.

Ok can change the set distance check to a drag over and get the outer distance / 2.0. Means you will have to search the dwg for missing bits.

 

Watch this space.

I have changed the code in my prior post.

@BIGAL okay I will give this a try. Thanks a lot for this.
