Command line: NUMBERSET
Sets the line number from one of three sources: a P&ID project, the current drawing, or a selected component.
P&ID
Requires a valid CADWorx P&ID project using an Access database. If the configuration file is the same as an existing P&ID project, this option automatically supplies all the line numbers within that project from the process lines table. The line numbers supplied are of the same format as the project. If the configuration file is not the same, a standard file dialog box displays requesting the location of the database to use.
Current Drawing
Sets the line numbers based on the current drawing. This option searches the entire drawing and displays all the line numbers in the Select Item dialog box. This option requires that the LineNumberSystem variable is set to 2. This is the same as selecting the System On (Static Size/Spec) option in the Line Numbering System dialog box. For more information, see Line Numbering System Dialog Box.
Component
Sets the line numbers based on a component that you select from the current drawing. This option searches the entire drawing and displays all the line numbers in the Select Item dialog box. This option requires that the LineNumberSystem variable is set to 2. This is the same as selecting the System On (Static Size/Spec) option in the Line Numbering System dialog box. For more information, see Line Numbering System Dialog Box.
