|You can add material to a surface in two
opposite directions by using the Thick Surface
capability. This task shows you how to do so.
In this section you will also find information about:
|Open the ThickSurface.CATPart document.
|Two contextual commands
creating the object you need are available from the Object to offset
If you create any of these elements, the application then displays the corresponding icon next to the Object to offset field. Clicking this icon enables you to edit the element.
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 Thick Surface feature and extract the geometry. Once the operation has been done, the Extracted Geometry (ThickSurface.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 Thick Surface operation.
Note also that if you have Generative Shape Design installed, the geometry resulting from the Extract operation is associative.
When adding a surface-based feature or a surface feature modifying another surface-based feature or surface belonging to the same body, Part Design features based on that second feature then reference the new added feature. In other words, a replace operation is automatically performed. For an example, refer to Creating Splits.
The application does not manage self-intersections between faces with opposite orientations. To avoid this type of 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 Thick Surface, ensure that the input body has enough space to be thickened.
