Introduction

Appending is a special insertion case where, the insertion occurs after the tail vertex of the polyline.

Splicing

Splicing polylines is basically inserting one polyline to another at an end. Below shows splicing/appending a provided polyline to an existing polyline:

  1. Append first vertex (Step II)

  2. Move vertex node tail to last vertex

  1. Add segment splice (Step III)

(Step V)

  1. Prepend segment splice to appended polyline.

  2. Append segment splice to existing segments.

  3. Move segment node tail to last segment
