Number the Spool Drawing

The numbering of spool drawings is normally used to provide full accountability and repeat ability through design changes. The parts numbers can be automatically applied to complete Spool Drawings, the default setting, or the parts can be numbered for each spool individually.

  1. To define what elements of the spools are to be numbered, select Settings > Numbering from the main menu to display the Numbering Settings window:

    All of the principle data for numbering settings are available from the Numbering Settings window.

  2. You can select what data has a number setting, click to check the appropriate checkboxes, from the Include part of the Number Settings window. After the selection has been made, you can define the Default spool prefix.

  3. Select how the numbering will be applied, from the part numbering drop-down list, you can choose to apply the numbering per SPLDRG or per SPOOL.

    The numbers shown in the Design Explorer are for indication purposes only. They only match the real spool numbers when the Spool Drawing is first numbered. When the numbering is updated after something has been changed (for example, inserted a field weld to split a spool) the members list numbers get out of synchronisation with the real numbers. The way the spools are numbered, once updating is applied can be changed by selecting from the three options in the Update Choice Handling part of the Numbering Settings window:

    • Use first available data - The first spool in which the data has changed will automatically pick up the first available number. When there are no more existing numbers new data is generated for any remaining spools.

    • Always generate new data - Existing numbers are ignored and new data is generated for all affected spools.

    • Manual data selection - The Select Data for Spool Element window is displayed from which you can select an existing number to use for the modified spool or whether to generate new data.

      The Select Data for Spool Elements window is populated with the Spool numbers and available attribute data.

  4. Click Use selected data to use the existing numbers or click Generate new data to use new numbers.

  5. Click Cancel to close the Select Data for Spool Elements window.

  6. Click OK to save the numbering settings and close the Numbering Settings window.

  7. Click Cancel to close the Numbering Settings window.

    To generate the numbering, select Update/Number from the SPOOLER tool bar, the Update/Number Spool Drawing window is displayed:

  8. Click Apply, the software carries out a check of the Spool Drawing numbering, this will take a few seconds and then displays the Update/Number Spool Drawing window, with the results of the check shown in the Status part of the Update/Number Spool Drawing window.

  9. Click Dismiss to close the Check Spool Drawing window.
