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.
• Offset draws the ray parallel to an existing entity.
