Line objects also have nodesA structural anchor point for a graphic object, usually visible as a small square box superimposed over a graphic. Nodes will be located separately at the start, at the end, and at every change in direction within a graphic object. ., but behave in a more restricted manner than Pipe, Polyline, or Polygon objects.
A straight line can only consist of two nodes, (a start node point and an end node point). These can be individually selected to move the line to a different position, or at least change its direction. The Line object does not support node adding. To achieve the same result as adding a node to a Line object, create a Polyline object instead. Deleting either of the (only two) nodes of a Line object will delete the whole Line object completely.
