tracing between two points

[subbup]

I have bunch of polylines connected together and forming a big network.
I know two points in that network take it as a start point and endpoint.
I want to trace possible routes between these points.
all polylines are in same layer and no hangings.

Any Ideas please

Hello Subbu and welcome!

What do you mean by "trace possible routes"? Do you need all of them? Or maybe what do you need is the shortest way? Or just any one, randomly?
I think it is possible to write a lisp for this, I will think about. Do you use a full version of AutoCAD, or just an LT?

Hai fuccaro,

first ofall mine is Autocad map 2004 full version.
In map we have a way to get shoetestpath between two points in a network.
But here I need all the possible routes in between two points.
I think you got it.
