Create Coco Table Form

The Coco Table can be used to construct a Connection Compatibility table which sets out all of the permissible connection pairs.

If an attempt is made to connect two pipework components in Design, then a check is made to see if the p-leave PCON attribute of the first component and the p-arrive PCON attribute of the second component appear as a matching pair in the connection table. If there is such a matching pair then the components are connected, otherwise a similar check is made on the p-leave PCON attributes of each component. If a matching pair is now found, the second component is ‘flipped’ and connected to the first. If no matching pair is found then an ‘incompatible connection type’ error message is output and the second component is left in its original position and orientation.

Create a Connection Compatibility Table

1. Select Create, then select Coco Table from the main window drop-down.

   The Create Coco Table window opens:

   

2. In the Name box, enter the name to be assigned to the new table.

3. Click OK.

   Note: The table will initialize with an error message if, for example, the table in question is from a read-only Master project.

   

   The table will still appear and the data in the grid will be readable but the table will be in read-only mode.

   The new Coco Table (CCTA) element is created in the database hierarchy, and the following form opens:

   

4. Select the required Connection types from the Available Connection Types list. Multiply selections can be made by holding down the CTRL key and using the left click on the mouse.

5. You can:

   • Add highlighted Connection Types to the Coco table by clicking the Add > option.

   • Add all available Connection Types to the Coco table by clicking the Add All >> option.

   • Remove a Connection Type from the Coco table by highlighting a light blue entry in the Coco table then click the Remove < option.

   • Remove all Cocos by clicking the Remove All << option.

     When a connection type is added from the Available Connections Types list to the Coco table, its value will be removed from the Available Connections list, and vice versa.

Coco Element Entry and Modification

6. Click an empty cell in the Coco’s table to display a drop-down list of connection types.

   Modifications to existing Coco configuration can be made by selecting a new value or deleting the configuration currently present to remove it.

   If a new connection type is required that is not available in the drop-down list, simply type a new value into the cell.

7. Click Apply to commit changes made to the table.

   The figure below shows a populated Coco table and an example of the drop-down values available when making a connection:

   

   Note: Changes made in the table are only saved when Apply is selected. Until then they are held in the life time of the form. If Dismiss is selected, the changes are lost.

Add and Remove Grid Data Columns

8. If additional columns are required in the grid they can be added by right clicking the mouse button in the Coco table header to display the following options:

   

9. Click Add Column to insert an additional Coco column to the table.

10. Click Delete Column to remove the Coco table.

    You are prompted to confirm this action:

    

11. Click Apply to commit changes.

12. (Optional) To remove a column, click on the column heading to make it active, then right-click to display a Delete Column option.

Specifying Pipe End Conditions for use by Isodraft

In the center bottom of the dialog is an Isodraft CKey drop-down. The drop-down becomes active once an entry has been populated in the Coco table.

This drop-down box can be used to view and also modify the currently configured Isodraft CKey for that particular Coco combination element in the table. Possible values are as follows:

• BW Butt Weld

• CP Compression

• FL Flange

• SC Screwed

• SW Socket Weld

• PL Plain

for further information on Isodraft, refer to ISODRAFT Reference.

Add a Connection Type Description

At the bottom-left of the Coco table form, there is a read-only text box labeled CType Description. When you select a connection type from either the Available Connection Types list or the Coco table, this box displays any previously created or modified Coco descriptions. These descriptions help guide the user when populating the form. To add a description:

13. Click the Create/Modify Coco Descriptions option.

    The Connection Compatibility Descriptions window opens:

    

    This form allows a long description to be added to Connection Types.

14. To add a description, select a Connection Short Code from the drop-down list.

15. In the Description field, enter an appropriate description of the Connection Type.

16. To discard changes and return to the Coco Table form, click Dismiss.

17. Click Apply to commit the change and add the description to the list.

18. To remove a description, highlight an entry in the list and click Delete.
