Create a new REM object that is offset a specified distance from an existing REM line, circle, or arc.
Offsets are especially useful for creating accurate parallel lines and concentric circles. When you offset a line, the new line is the same length as the original.
You can specify the offset distance by clicking a through point, drawing a line segment, or entering a numeric offset value. This offset distance is used as the default value for the next use of the offset command in this editing session.
