Break 3d Polyline @ vertices

I'm in search of a good lisp that will ssget all 3d polylines & break at the vertices.

Thanks!

Doesn't Explode do what you want

I want to retain the x,y,z values

Explode does not alter the x, y, z values. It merely breaks the 3D polyline at each vertex.

Thanks eldon, but the entity needs to remain a 3dpolyline for use in another software.
