This operation produces a new shape that is parallel to the shape of the picked outline. This new shape may be inserted into the original shape or it may become a new independent object. Only one outline can be offset at a time and it must be planar.
This operation requires two clicks. The first click picks the outline and starts the interactive operation. The second click ends the interactive offsetting and determines the final offset distance. If offsetting is toward the inside of the face, the new shape is automatically inserted into the face, when the Insert option is on. If offsetting is toward the outside or the Insert option is off, a new separate object is created.
