Piping Input menu: Global > Change Sequence

Block Operations toolbar: Change Sequence

Changes or rearranges the sequence (order) of elements while preserving the geometry.

Why use the Change Sequence command?

Typically, the Elements dialog box displays by the order of elements entered during the input process. The order in the list is important because when you specify an input value for an element in the list, that value propagates to all the elements in the list following it UNTIL the value is explicitly changed.

When you import piping model data (in the form of PCFs) from other piping input design software such as Intergraph Smart3D, CAESAR II imports the elements in one sequence. However, that sequence may not be what you want. For example, you may want all the high-pressure elements to be listed together. This reduces the number of unique input fields to verify and can help you to logically organize the model. You can re-organize elements in a way so that those with similar carry-forward properties are placed consecutively.

To change the sequence of elements

  1. Select the block of elements (nodes) whose sequence you want to change, either from the Elements dialog box, from the 3D Graphics pane, or from Line Numbers dialog box.

  2. Click Change Sequence in the Block Operations tool bar.

    Alternately, you can right-click in the Elements dialog box, and then click Block Operations > Change Sequence.

    The Change Sequence dialog box displays.

  3. Choose where in the list you want to move the selected block.

    • To move the selected block after a given element, click Follow.

    • To move the selected block before a given element, click Precede.

    The cursor changes to indicate the operation is in progress.

  4. From the Elements dialog box, position the cursor in the line where you want the selected block to be placed. Alternatively, you can select elements in the 3D Graphics pane and then click on the element where you want to move them.

    The selected block of elements displays in the new order.

    The 3D graphics model does not change. This command only affects the Elements dialog box display contents. Remember that this command provides you with the capability of organizing "like" types of elements together.

    To re-store the order of the Elements dialog box to the original list, use the Undo button.
