    Select a cylinder as shown below:
     

  5. Select Line 2 in the geometry area. Select a second cylinder.

    The dialog box current selection field is automatically updated.

  6. Select the planes as shown below:

    The Current selection field is automatically updated.

    The specification tree is updated.

  7. Click Ok.
