converting single 3dpolyline zigzag string into two separate 3dpolylines

[pyou]

Is it possible to convert a single 3dpolyline zigzag string into two separate 3dpolylines using a lisp code?

 

Images attached 

 

Thank you for help!

This should get you close to what you need. with minimal error handeling only allows you to select 2 polylines at a time & they have to have the same number of vertex for this to work.

see Images, original 3d polyline before is a zigzag and after are two separate 3d polylines. What you don't understand?

yes mhupp it is supposed to be opposite. Zigzag is original 3d polyline and two new 3d polylines needed.

 

I have attached example of zigzag 3d polyline

Top down is usually how things flow. I guess you got an undo lisp now.
