The Line node generates a mask in the form of a straight line segment. The segment is defined by two points, point 1 and point 2, forming the two ends of the segment.

Points 1 and 2 can be moved using the manipulators or their X and Y coordinates can be entered manually in the node properties.

If the coordinate values of a point are constrained
by a value from an optional input connector, the manipulator
associated with these coordinates is not displayed. In the example
below, the coordinate values of point 1 are from another node;
therefore, the manipulator of point 1 no longer appears.

To add an Line node, right-click in the Graph Editor and select
**Create Node > Mask Generation >
Line** or press the keyboard shortcut **N-L-I**
(Node Line).

Double click on the node to open its parameters:

To edit the Line node:

**Preset**: List of existing size presets. Select one from the list to apply the size preset.**Width**: Width of the mask to generate in number of vertices.**Height**: Height of the mask to generate in number of vertices.**Quad size**: Size of the quads of the mask in meters.**Points 1 and**2: These points define the ends of the line. Use the sliders to adjust the point's X and Y coordinates.

The X and Y coordinates of each of the two points are relative to the center of the mask with a value between -1 and +1:- 0 corresponds to the middle in width (X), in height (Y); (0,0) positions the point in the center of the mask.
- -1 and 1 correspond to the minimum and maximum values of the coordinates (limit of the mask); (1,1), (-1,1), (1,-1), and (1,1) position the point in one of the four corners of the mask.

**Line – Width**: Adjusts the thickness of the line from 1 to 20.

The Arc and Line
nodes can be used in components to propagate the coordinates of
their respective points, allowing the formation of a circuit. An
end point of an Arc can be linked to an end point of Line to
guarantee a permanently valid link between the different masks.
This is used in the Road sample, available in
the **Help > Samples** menu.

Components can be retrieved from this sample project in the
Models window > Mask generation > Circuit - Arc or Circuit -
Line, and then right, click and select **Export
component**.
