Enclosed Objects:
The Left < Offset directional button will offset an enclosed object to the outside.
The Right > Offset directional button will offset an enclosed object to the inside.
Arcs and Curves greater than 180 Degrees use the same rules as closed objects.
Unenclosed Objects:
For unenclosed objects the directional arrow buttons depend on the direction of travel of the vector segments, starting from the line’s start point.
Left < Offset directional button offsets Clockwise
Right > Offset directional button offsets Counter-Clockwise
If it doesn’t Offset in the expected direction, click Undo and click the other Offset directional button.
