Nodes

A node represents a point that is attached to ends of an edge or an isolated point.

Nodes are integral to the snapping process and, in the case of the 'Edge Split Edges' snapping type, a new node can be created. For more information please refer to Snapping.

Note: Nodes are represented in the system datastore as sys:node and have an ID and point geometry.

A node can use the following references:

Reference	Description
`sys:edge_to_node`	A `sys:edge` and a `sys:node` are related by `sys:node_to_edge` if the node is at the start or end of the edge.
`sys:face_to_node`	A `sys:face` and `sys:node` are related by the reference if the node is isolated and contained by the face.
`sys:point_to_node`	A feature and `sys:node` are related by the reference when a node represents the feature in the topology.
