Ray Command in AutoCAD

The Ray command in AutoCAD is used to create a ray, which is a line that starts at a specified point and extends infinitely in one direction. Unlike a line, which has two endpoints, a ray has only one endpoint and continues indefinitely in a specified direction. The Ray command is often used for geometric constructions, such as angle bisectors, or in cases where you need to represent directional elements in your drawings.

How to Use the Ray Command

Follow these steps to create a ray using the Ray command:

Step 1: Activate the Ray Command

To start the Ray command, you can:

  • Type RAY in the command line and press Enter.
  • Click the Ray icon from the Draw panel or ribbon (if available).

Step 2: Specify the Start Point

Once the Ray command is activated, AutoCAD will prompt you to specify the start point for the ray. You can:

  • Click a point in the drawing area to define the start point of the ray.
  • Enter the coordinates of the start point directly in the command line (e.g., 10,10) and press Enter.

Step 3: Specify the Direction

After defining the start point, AutoCAD will prompt you to specify the direction in which the ray will extend. You can:

  • Click a point in the drawing area to define the direction of the ray.
  • Enter the angle or direction in the command line (e.g., 45 degrees) and press Enter.

Step 4: Complete the Ray Command

Once the direction is specified, AutoCAD will create the ray, which will extend infinitely in the defined direction from the start point. To complete the command:

  • Press Enter or Esc to finish the command.

Applications of the Ray Command

The Ray command is commonly used in the following applications:

  • Representing geometric constructions like angle bisectors or projection lines.
  • Creating directional lines or guides that extend indefinitely in a specific direction.
  • Drawing reference lines in technical drawings where a line only needs to extend in one direction.

Conclusion

The Ray command in AutoCAD is a valuable tool for creating lines that extend indefinitely in a specific direction from a starting point. Its use is particularly helpful in geometric constructions, architectural plans, and engineering designs where a directional line is needed.
