Creating a Shell

Shelling a feature means emptying it, while keeping a given thickness on its sides. Shelling may also consist in adding thickness to the outside. This task shows how to create a cavity.

Before you begin: Create a volume with a face to be removed.
  1. From the Volume section of the action bar, click Shell .
  2. In the Faces to remove box, select the face(s) to be removed.
    The Support Volume box is filled with the volume owning the selected face.

  3. In the Inside thickness box, enter the value or use the arrows to change the thickness value.
  4. Click OK.
    The feature is shelled: the selected face is left open.

  5. Double-click the shell to edit it.
  6. In the Other thickness box, select a face.
  7. Double-click the thickness value displayed on this face.
  8. Enter a value in the dialog box that appears and click OK.
    The length between the selected face and the shell is now 10mm.

  9. Select the Smoothing mode.
    OptionDescription
    None No smoothing is applied. This is the default option. The Max deviation and Constant thickness boxes are disabled.
    Manual Lets you enter a maximum deviation. The default value is 0.1 mm. The Constant thickness box can be selected to apply a constant thickness.
    Automatic Smoothing is applied automatically. The Max deviation box is dimmed. However, the Constant thickness box can be selected to apply a constant thickness.
  10. Click OK.
