To Create Offset Draft Geometry
Using the Offset command, you can create offset draft geometry from other draft entities or model geometry. If the parent object is scalable, for example scalable view geometry, or if parametric sketching is enabled when you create the offset line, the new geometry updates with any changes to the parent geometry.
