# Perpendicular Line (G Dataflow)

Computes a perpendicular line that passes through a point and is perpendicular to a reference line.

This node also returns the distance from the point to the line.  ## line

Cluster of two point coordinates defining the reference line. ## point

Cluster that specifies the coordinates of a point. ## error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error  If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error ## perpendicular line

Perpendicular to the reference line and passing through the point.

A cluster of two point coordinates defines the perpendicular line. The first point of this cluster is the input point. The second point lies on the line. If point lies on line, the first point of perpendicular line is not the same as point. The second point of perpendicular line is point, and the first point lies on the line perpendicular to line. ## distance

Shortest, or Euclidean, distance from the point from the line. ## error out

Error information.

The node produces this output according to standard error behavior.
