Select a Creation Mode

The Hangers form offers three modes to create hangers.

Figure 5:4. Hanger Creation options

The options are:

Create and Modify (default mode)

1. Enter the hanger name in the Name input field.

   The application displays the hanger form.

2. Modify, accept, or cancel the hanger.

3. If you require another hanger, re-display the Hangers form.

Create Once

This mode creates multiple hangers of the same configuration, or of different configurations, using a minimum of keystrokes.

4. Identify the pipe and the beam(s) required.

5. Click OK.

   The application creates the hanger and activates the ALL button of the hanger configurations form:

6. Enter the name of the next hanger (if any).

7. Click on a filter button.

8. Identify the tube and the beam(s) and create the next hanger.

   The hanger can be cancelled or modified only by first accepting it and subsequently deleting it or modifying it. Refer to ‘Modifying a hanger' (see Modify a Hanger).

Multi Create

This mode quickly creates multiple hangers of the same configuration.

• Click OK.

  The application creates the hanger and prompts you to select a new pipe and beam(s) for the next hanger.

  The hangers are named automatically using the naming convention set by the MDS administrator.

Example:

In this example you will create a hanger configuration of type T1 M2 B6. You will use the name HANG1.

9. Confirm that the current create mode is Create and Modify.

10. Click OK.

    The Hanger form is displayed.

    

    The application creates the hanger using the data entered in the hanger configuration form.

    If the selected beam intersects with the pipe, then the hanger is positioned at the intersection point. In this case the Distance and Through buttons become deactivated as the hanger cannot be moved while it is connected to the beam.

    You can still move the hanger using the Reconnect To Another Beam icon .

    If the beam selected is parallel to the pipe, the hanger is positioned as close as possible to the start of the identified beam.

    The application tries to locate the position by moving the hanger along the beam until the hanger can be connected vertically.

    If the application cannot find a valid connection point on the beam, then an error message is issued and you are allowed to select another beam.

    If a valid connection point is found, then the application creates the hanger. In this case the Distance and Through buttons become activated, allowing you to modify the position of the hanger. Moving the hanger with these buttons also moves the steelwork connection point(s) and associated fitting(s) accordingly.

    When creating the hanger, the application does the following:

    • Creates an atta in the identified tube.

      The atta name is the same as the hanger name. If the hanger configuration is such that the hanger is connected directly to the pipe, then the hanger is connected to this atta.

      If the hanger configuration is such that the hanger is connected to the pipe through a trunnion, a welded lug, or any other standard pipe support, then the hanger is connected to the atta of the standard support. The Stex attribute of the hanger atta is set to: Connected to <standard_support_name>. In this case the cref attribute of the hanger atta remains not set.

    • Creates the fitting(s) as a member(s) of the steelwork section(s). In the case of a double-channel beam, the fitting is created in only one of the steelwork sections. The name of the fitting is the name of the hanger appended by /FITT/H and by the fitting sequence number (for instance: /HANG1/FITT/H1).

    • Creates the hanger and connects it to the atta and to the fitting.
