TIP
An effective drawing technique is to offset objects and then trim or extend
their ends.
Use OFFSET to offset the following object types:
■ Lines
■ Arcs
■ Circles
■ Ellipses and elliptical arcs (resulting in an oval-shaped spline)
■ 2D polylines
■ Construction lines (xlines) and rays
■ Splines
Special Cases for Offset Polylines and Splines
2D polylines are offset as individual line segments, resulting in either
intersections or gaps between segments. To complete the offset, intersecting
lines are trimmed and gaps are filled.
