Creates an offset surface with the specified distance from the original surface. For each selected surface composite a vector handle is displayed in the graphics area to control offset distance and direction.
Creates a quick offset that allows you to specify the Deviation Tolerance. Spans are edited (added or removed) until the specific deviation tolerance is reached, or the maximum number of spans are reached.
The structure and parameterization of the original surface is used as input. Each CV is moved in a certain local offset direction as far as required to get the most accurate result.
Allows you to control the degree and the number of spans for the surface offset.
The surface offset is created based on the original degree and the original number of spans, but the parameterization is adapted to the new shape.
Specifies the distance between the original surface and where the surface offset is created. You can specify a positive or negative Offset Distance value to create a surface offset on either side of the original surface. You can also drag the arrow head in either direction to change the Offset Distance value positively or negatively.
Allows you to specify explicit U and V degrees for the surface offset. This option only appears if the Explicit offset mode is selected.
Specifies the U degree for the surface offset. This option only appears if the Explicit Degree option is selected in Explicit Control Options.
Specifies the V degree for the surface offset. This option only appears if the Explicit Degree option is selected in Explicit Control Options.
Allows you to specify a minimum UV degree for the surface offset. This option only appears if the Explicit offset mode is selected.
Degree - Specifies the minimum UV degree for the surface offset. This option only appears if the Min UV option is selected in Explicit Control Options.
Allows you to specify explicit U and V spans for the surface offset. This option only appears if the Explicit offset mode is selected.
U Span - Specifies the U spans for the surface offset. This option only appears if the Explicit Spans option is selected in Explicit Control Options. V Span - Specifies the V spans for the surface offset. This option only appears if the Explicit Spans option is selected in Explicit Control Options.
Allows you to specify a maximum number of UV spans for the surface offset. This option only appears if the Explicit offset mode is selected.
Spans - Specifies the maximum number of UV spans for the surface offset. This option only appears if the Max UV option is selected in Explicit Control Options.
Controls the accuracy of the offset result. The Deviation Tolerance option is only available if the Automatic offset mode is selected.
Specifies the minimum length of spans for the surface offset. The Min. Spans Length option is only available if the Automatic offset mode is selected.
Improves the reachable offset accuracy by shrinking the base of a trimmed surface. When enabled, any trimmed surface is converted to a natural surface using a trim convert operation.
The edges of the offset result are calculated with respect to Deviation Tolerance if it is available.
Creates an offset surface on both sides of the original surface. The Offset values apply to both offset surfaces. The offsets of the surface cannot be controlled independently.
Creates closed geometry from an offset surface and the original surface. This option joins the free edges of offset surfaces to edges of the original surface. If Both Sides is enabled, creating two offset surfaces (top and bottom), the edges of these surfaces join to create the closed geometry instead of the original surface. In the Object Lister, the wall geometry appears under the Offset Wall sub-group.
An additional matching process is applied to the offset result to restore the original continuity.
The reached offset accuracy is lost in order to get better continuity.
Specifies the transition continuity of the surface offset.
If selected, any changes in any field of the control box lead to an automatic update of the model display. Auto Update is enabled by default.
Adds a continuity locator to the surface offset indicating the level of continuity.
Shows the deviation of the surface offset. Show Deviation is disabled by default.
Saves the history of the curve offset so you can modify the offset later. Create History is enabled by default.
Specifies whether the Curve & COS Offset tool creates history metadata. Create Metadata is enabled by default.
The Create Metadata option is available only with Autodesk Alias 2019.2 or later.
Lets you specify whether or not to create a COS when applying a surface offset. Previous to Alias 2022, a COS was created by default when you applied a surface offset with this tool.
