Active

On the Home tab, the Active group contains the following tools.

Diagram

In the Active group, the Diagram field shows "No Active Diagram" if no diagrams are open, otherwise it shows the name of the currently active diagram. If you have several diagrams open, you can change the active diagram from the drop-down menu.

You can also change the active diagram from the Arrange Windows menu in the P&ID status bar. There you can also see whether each diagram has been opened in "edit" or "browse" mode.

For more details on the status bar, see User interface.

Colors

In the Active group, the Colors field displays what is the current coloring mode of the active diagram. Opening a diagram sets the coloring mode to the default, which is "By System", and you can select a different coloring mode from the drop-down list.

These coloring modes are available:

  • By System – Objects are colored according to their System. System colors are defined in File > Environment > Systems and Lines.

  • By Nominal Size (NS) – Objects are colored according to their Nominal Size value.

  • By Piping Specification – Objects are colored according to color definitions in piping specifications. If valves and pipe run parts use another specification than the first specification option from the pipeline, project administrator must add the required specification columns to the ARMATURES table—see ARMATURES.

  • By Insulation Specification – Objects are colored according to color definitions in insulation specifications.

  • By eShare Data – Objects are colored according to an object categorization obtained from CADMATIC eShare. You can use this function when your Windows account is defined in the eShare user list and eShare project administrator has given your account permission to access the specified data.

  • By Compartment – Objects are colored according to compartment (if defined in the object data).

  • By Linked Object – When the same P&ID data object has multiple instances in the active diagram or in different diagrams, those object instances are linked, and this option allows you to easily see which objects in the active diagram are linked objects. The colors also indicate whether the linked object is owned by the active diagram or some other diagram. For more information on the linking, see Manage linked objects.

  • By Database Columns – Objects are colored according to values of one or more database columns.

System

In the Active group, the System field lists the Systems that can be assigned to diagram objects whose type is 'Equipment'.

The System that is currently selected in this field is the active System that is used if you assign a System to existing Equipment as described in Assign System to Equipment.

If a System that you intend to use in the active diagram is not listed, use the Select System option to add the required Systems to the list.

If the list contains Systems that you do not intend to use in the active diagram, you can remove them with the Clean unused tool.

The project administrator can set the active System to be used when new Equipment is inserted into any diagrams, as described in System Default.

Assign System to Equipment

You can assign a System to diagram objects whose object type is Equipment. This can be DEFAULT_SYSTEM or a System that your project administrator has defined.

Do the following:

  1. On the Home tab, in the Active group, select the System you want to assign. If the required item is not listed, select Select System to see a list of all Systems.

  2. Click the (Assign) button. Objects that are already using this System are highlighted in the diagram.

  3. Select which objects to include in this System:

    • Click a highlighted Equipment to remove it from this group.

    • Click a non-highlighted Equipment to add it to this group.

  4. Press Enter to accept the group of objects.

Clean unused

You can remove the Systems that the active diagram does not use from the System drop-down list by clicking the (Clean unused) button.
