This command extends a line or polyline, or creates a new line or polyline from an existing one, using a specified distance. The new segment of the line or polyline is drawn from the current position in the direction indicated by the current position arrowhead.
You start by selecting an existing line or polyline. Initially, the current position is the closest vertex to the location where the line or polyline was selected. Extending from the endpoint of a polyline will add a new point to that polyline, while extending from any other point will create a new polyline.
There are two modes of operation: draw mode (D) and move mode (M). When you are in draw mode, extending will draw line or polyline segments. When you are in move mode, the current position arrowhead can be moved without drawing segments. The orientation of the current position arrowhead can be changed with the Right, Left, and Angle commands.
Here is a list of the Extend by Distance options:
