The Offset tool is designed to offset selected segments on the plane.
Defines the object plane for the offset operation.
The offset operation can be performed in two ways:
Single - offset is performed on one side only
Double - offset is done on both sides
Defines the offset distance.
If enabled, connects the ends of offset segments.
If enabled, the selected base curves are removed.
If enabled, the ends of offset curves are adjusted to copy the end tangent of the original curve.
