Actually, when you think deep enough even further from previous thought, you'll realize that there may exist case when both sel. sets s1 and s2 are the same - XLINE just nearly passes through two edges that are on extent of boundary... In that situation you'll have to use still my previous version solution - only the smallest REGION of more of them obtained as common members from both sel. sets s1 and s2 is taking in consideration for deriving LWPOLYLINE or SPLINE which is then used in COPYBASE, UNDO, PASTECLIP commands... I hope this is now final version :

Since command ISOLATEOBJECTS was introduced in A2011 before OFFSETEDGE command in A2012, I've decided to implement it in code, as it was coded for A2012+ versions... Of course if you have A2012- you should remove last derivation of LWPOLYLINE or SPLINE entity from REGION at the end of the code and remove this intervention with command ISOLATEOBJECTS (A2011-)... This intervention is needed for using if you have ISLANDS and as LISP wasn't written to operate with them I implemented line :
(command "_.ISOLATEOBJECTS" ss "")
just after selection was made to make sure you don't need to put ISLANDS on separate LAYER or something like that, but make sure you don't select ISLANDS... That's it, hope you can find it useful in some situations... Regards, M.R.

Marko, It is possible that smaller areas affected in these cases. Which I do not think the islands - they are not isolated.

Marko,
In cases of "invalid" it is visible that temporal REGION's are created. Almost all possible. Though, obviously not all necessary. And often duplicated. Probably, it is necessary to create all REGION's, but only minimum possible.
Creation is temporal all possible REGION's - possible option of what I called earlier "to create model of all lines".
For example, there is already old FlashPolygons. Works very quickly - that is there is a hope that it is possible to repeat success.
When all polygons are found, to find in what pick point, already simply.
And the task of creation of all possible polygons is very valuable directly too.

Perhaps, it is useful:

Alex, computer can't think... If you can describe what is exactly failing with your testings, what are expectations and so on, maybe someone willing to reply can make it possible to solve the problem... I am testing the code I posted and I had no unsatisfactory results... Maybe with some special case it bugs, but I wrote on what was known to my knowledge and available implementations of ALISP functions... Previous link is pointing to program that's written for baying and it's protected vlx routine... To my knowledge I am unable to use it and even if I could I don't want to spoil someone's business or plans with written author rights... If you find my offered code have lacks then the best is to try to fix them with your own skills... I thought you can appreciate my willing to help you in request you were searching... I know I maybe don't have more advanced skills, but like I said the code is written to be a simple alternative to BOUNDARY command and it certainly is doing similar operation not as fast as it could be, but as good as mentioned command is currently doing... If not for learning then it was good task to find some inspiration and maybe someone can build on it further more... Thank you for pointing additional links that may be useful for tackling the task from other point of view but I think that even now "bndr.lsp" has also its advantages over pointed FlashPolygon and TotalBoundary plugins, for which I don't want to give wrong opinions... Certainly they all serve for what they were written and if the task is simple then all of this would be free... Simply the task you asked for solving is taking time and dedication so the best is to try to use what you have and build on knowledge or stuff you think is useful in for that reason I wish you good luck in programming and soon and good result of your work we'll all appreciate...

Marco, is sorry for me that I can't be the real assistant. Thank you for your efforts and desire to help!
It is possible that this problem isn't solved on LISP or very difficult decides.
It is possible that it is really difficult task.
It is possible that for the solution of this task it is necessary to solve two other complex problems - creations of "model" of all lines and very fast processing of huge number of lines.
I am not a programmer. I can only look for solutions, wait, test and give unsuccessful advice.

Just got the first version for testing:
The solution is possible!

It would be helpful if region objects had some kind of coordinate data to work with.
Does anyone know how to decipher all that dxf 1 code gibberish?
