# EPANET: [VERTICES]

[VERTICES]

Purpose:

Assigns interior vertex points that describe the shape of network links.

Format:

One line for each vertex point in each link containing such points that includes:

- Link ID label
- X-coordinate
- Y-coordinate

Remarks:

1. Vertex points allow links to be drawn as polylines instead of simple straight-lines between their end nodes.
2. The coordinates refer to the same coordinate system used for node and label coordinates.
3. A [VERTICES] section is optional and only provides support for an external GUI program that uses the EPANET engine.
