Line

Encapsulates data for a boundary line. A line can be a single line segment with two vertices or multiple connected line segments (a polyline) with more than 2 vertices.

Example

"lines": [
	{
		"name": "driveway south entrance",
		"vertices": [
			{
				"x": 1302,
				"y": 159
			},
			{
				"x": 1047,
				"y": 480
			}
		]
	}
],

Attributes

Name	Type	Description
name	string	the line name. This name will be referenced by line cross conditions.
vertices	array of Vertex	an array of vertices that form the polyline.

The line cross direction needs to be used when you reference the line in a line cross condition. To determine the direction of the line, imagine your right handle against the computer screen with your fingers extended, the left side of your palm against the screen and your extended thumb sticking straight out from the screen. Your fingers should be pointed from the first vertex in a line segment to the second vertex for that segment. If you curl your fingers 90 degrees toward your wrist, your fingers will now point in the positive line cross direction.
