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.
