This command works on 3D lines as well as lines that lie on a single plane.
Example: Draw a line parallel to a multi- segment line.
Select the Parallel command. Set a point on the line and move the cursor away from it. A rubber- band line is drawn parallel to the first line at the current cursor distance. When the line is where you want it, set the second point.
