title: breaking polylines on join spot in autocad - any lisp function?
body: <p>i am trying to break a poly line where an other poly line has joined the first line. for example in three ways that there are two lines, (one main road and one  by-way) i want to break  the main road on the joint spot of two poly lines and make 3 individual lines.
  so is there any lisp function or something like that , which can do the routine for all the poly lines in my map ?</p>
