Hi,
Not quite sure how the union or combine works. Say I have two polyline shapes, L1 has 3 points (A, B,C), L2 has 3 points (D,E,F), after union these two polyiines together, will I get a polyline which connects A,B,C,D,E,F together? Or will I get a polyline with two sections: A->B->C, then D->E->F?
I need the first combined polylines, which means if another line passes through C and D, the combined polylines will intersect with it..
Any help or code snippet is greatly appreciately.
