Infinite Lines

Command: XLINE

The Xline command creates infinite lines.

An Infinite Line is a line through a given point, oriented at a specified angle and extending to infinity in both directions. Because infinite lines extend to infinity, they are not calculated as part of the drawing extents. The default method for drawing an infinite line is to select a point and then specify its direction.
