Drawing rays

A ray is a line in three-dimensional space that starts at a point and extends to infinity. Because rays extend to infinity, they are not calculated as part of the drawing extents. The default method for drawing a ray is to select the start point of the ray, and then specify its direction. You can draw a ray in any of the following ways:

  • Horizontal draws the ray parallel to the x-axis of the current user coordinate system (UCS).
  • Vertical draws the ray parallel to the y-axis of the current UCS.
  • Angle draws the ray parallel to a specified angle.
  • Bisect draws the ray perpendicular to an existing entity.
  • Parallel draws the ray parallel to an existing entity.

To draw a ray

  1. Do one of the following:
    • Choose Insert > Ray.
    • On the Draw 2D toolbar, click the Ray tool ().
    • Type ray and then press Enter.
  2. Specify the start point.
  3. Specify the direction.
  4. To complete the command, press Enter.


Start point (A) and direction (B).
