◦ 
Standard—Offsets a single quilt, surface, or solid face.
Standard—Offsets a single quilt, surface, or solid face.◦ 
With Draft—Offsets the region of the quilt or surface that is included inside a sketch, and drafts the side surfaces. You can also create straight or tangent side surface profiles with this option.

◦ Standard
Standard▪ Fit—Select a surface fit type:
▪ Normal to Surface—Creates an offset in the direction normal to the surface.
▪ Special Handling collector—Displays surfaces to Exclude from the offset operation, or surfaces to use to create an Approximate offset.
You can select an individual surface from the list, and then select the type of special handling, or you can select one of the commands below.
▪ Auto—Populates the Special Handling collector with surfaces that cannot be offset without special handling.
▪ Exclude All—Excludes all the surfaces in the collector from the offset operation.
▪ Approximate All—Creates approximate offsets for all of the surfaces in the collector.
▪ Attach approximate offset surfaces check box—Creates attached approximate offset surfaces when the approximate surfaces cannot be merged with the standard offset surfaces.
▪ Automatic Fit—Offsets the surface along the axes of a coordinate system.
▪ Controlled Fit—Scales and fits a quilt along the specified axes of a coordinate system.
▪ Coordinate system collector—Displays the coordinate system used to scale and fit the offset.
▪ Allow translationX, Y, and Z check boxes—Translates along the selected axes.
▪ Create side surface check box—Creates side surfaces to connect the selected surface and the offset surface. You cannot create side surfaces when the offset geometry contains approximate offset surfaces.
◦ With Draft:
With Draft:▪ Fit—Select a surface fit type:
▪ Normal to Surface—Creates an offset in the direction normal to the surface.
▪ Translate—Translates the offset surface in a selected direction.
▪ Side surface normal to—Sets the normal reference to Surface or Sketch.
▪ Side surface profile—Sets the surface profile to Straight or Tangent.
◦ Expand:
Expand:▪ Fit—Select a surface fit type:
▪ Normal to Surface—Creates an offset in the direction normal to the surface.
▪ Translate—Translates the offset surface in a selected direction.
▪ Direction reference collector—Displays a direction reference for a translation offset.
▪ Expand area
▪ Whole Surface—Expands the entire selected surface.
▪ Exclude loop—Specifies a region to exclude from the expand operation.
▪ Sketched Region—Expands a portion of the selected surface that is defined by a sketch.
▪ Sketch collector—Displays a sketch for an offset.
▪ Define—Opens Sketcher.
▪ Edit—Opens the section in Sketcher.
▪ Side surface normal to—Sets the normal reference to Surface or Sketch.
◦ Replace:
Replace:▪ Keep replace quilt check box—Creates a new surface face from a copy of the reference quilt.
