About the Offset Surface User Interface
The
Offset tab consists of commands, tabs, and shortcut menus. Select a surface and click
Model >
Offset to open the
Offset tab.
Commands
• Feature creation type:
◦ 
—Standard Offset
◦ 
—Offset with Draft
◦ 
—Expand
◦ 
—Replace Surface
• 
box—Sets the offset value.
• 
—Flips the direction of the offset.
• Special Handling collector—Displays surfaces to exclude from the offset when
is selected.
• 
collector—Displays a sketch for an offset when
Offset with Draft or
Expand is selected.
◦ —Flips the material side of the sketch when
Expand is selected.
• 
collector—Displays a quilt or datum plane to replace the selected surface when
Replace is selected.
• 
box—Sets the angle for the offset when
Offset with Draft is selected.
Tabs
The tabs are context-sensitive depending on the type of offset selected.
• References
◦ Offset surface—Displays a surface to offset when
Standard Offset or
Replace Surface is selected.
◦ Offset surface sets—Displays the surface sets to offset when
Offset with Draft or
Expand is selected.
▪ Details—Opens the Surface Sets dialog box so you can modify the surface set properties.
The remaining elements of the References tab are context-sensitive depending on the type of offset selected.
◦ Offset with a Draft:
▪ Sketch collector—Displays a sketch for an offset.
▪ Define—Opens Sketcher.
▪ Edit—Opens the section in Sketcher.
◦ Replace Surface:
▪ Replace quilt collector—Displays a quilt or datum plane to replace the selected surface.
• Options—The Options includes commands for setting a surface fit, creating approximate offsets or excluding surfaces from the feature, and defining side surfaces.
◦ Standard Offset:
▪ 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.
◦ Offset 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:
▪ 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 Surface:
▪ Keep replace quilt check box—Creates a new surface face from a copy of the reference quilt.
• Properties
◦ Name box—Sets a name for a feature.
◦ 
—Displays detailed component information in a browser.
