|Sometimes, some thicknesses have to be added or removed before machining the part. This task shows you how to add thickness to a part or use thickness as a local modifier on a part.In this section you will also find information about:|

|The options in the Deviation parameters section are disabled, when the CFO license is not available.|
In some specific cases, the application cannot offset the selected face. An error message appears informing you that the body cannot be built properly. After closing that window, another message appears proposing you to ignore the faces causing trouble. If you accept that solution, the thickness is added to the selected face and the face causing trouble is removed.
Ignoring faces in many cases avoids a costly and difficult manual rework of the part.
The fillet icon is still displayed in the specification tree. If you edit the thickness, the ignored face is previewed:
Sometimes, you will need to use the Extract command to be able to add thickness to a face. The Extract capability lets you generate separate elements from initial geometry, without deleting geometry. This command is available after clicking a dialog box prompting you to deactivate the thickness feature and extract the geometry. Once the operation has been done, the Extracted Geometry (Thickness.1) node is displayed in the tree. This category includes the elements created by the application.
The Extract capability is available if only one face was selected to perform the thickness operation.
Note also that if you have Generative Shape Design installed, the geometry resulting from the Extract operation is associative.
The application does not manage self-intersections between faces with opposite orientations. To avoid self-intersections, the thickness value must be lower by half than the minimal distance between faces belonging to the same body, with opposite orientations. If this rule is not respected, the application cannot produce a valid body.
Before using Thickness, ensure that the input body has enough space to be thickened.
