Use the Gas Tracing Options to determine how results are displayed and which features the trace recognizes as barriers.
Results Format: Select the format in which you'd like the results to be displayed. This option may also be set using the Results as Selection toggle button on the ArcFM Gas Trace toolbar. You may change this option after the trace has been executed. If you switch from Drawings to Selection, the current trace results will be converted to a selected set when you click OK. If you switch from Selection to Drawings, the current trace results will NOT be converted to graphics.
Results Content: Use the Results Content field to indicate the features that should be included in the trace. The ArcFM Gas Valve Isolation trace ignores this setting.
Select a barrier for the type of trace you will perform:
- Pressure System: Select All regulators or Regulators with different inlet and outlet pressures. The All regulators option will stop the trace at a regulator regardless of its pressure.
- Valve Isolation: Select All valves or Critical Valves. Critical valves are indicated by the Operating Classification field (Critical/Inspection Required and Critical/Inspection Not Required). If you select Critical Valves, the Include Valve tool will become enabled on the Gas Isolation Traces toolbar and allow you to include non-critical valves in the trace.
- Gas System: Select Town Border Stations or Regulators to indicate where to stop the trace.
The Temporary Marks field allows you to determine how the Clear All button works on the Gas Traces toolbar. This button may be used to clear temporary marks placed using tools on the Gas Valve Isolation toolbar. Select the "Clear temporary marks" checkbox to include temporary marks with Clear All. Designate which temporary marks using the checkboxes for the individual types.
Select the "Run trace after placing temporary mark" checkbox to execute the trace immediately after the temporary mark is placed. If this box is left unchecked, you will have to select the trace tool and click the starting point on the map to initiate the trace.
