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.

•    Offset draws the ray parallel to an existing entity.
