As the System Classification is greyed out by default, direct switching is not possible.  Two methods are demonstrated here.

Method 1

  1. Disconnect the pipes from the fitting
  2. Reconnect by stretching it back to the fitting
  3. You can also use “Trim ” command for reconnection

Method 2

  1. “TAB” key & select the fitting

(System browser opens from View tab -> User interface -> System browser)

  1. Once it is selected, press the delete key so that the system of fitting is deleted.
  2. Then you can reconnect the pipes by previous methods, ie by stretching the pipes or by “Trim” command
