3. Select parts or surfaces that form a closed volume.
   Select elements if needed for the By Connectivity fix method.
4. Define a fix method.
   • By Ray Tracing - This option works best if the input almost forms a closed volume.
   • By Connectivity - Use this option to fix normals on few remaining elements. For this method, it is not required that the input forms a closed volume.

     Choose whether to update or reverse the normals.

5. Click Fix.
