Gas Trace Options

Use the Gas Tracing Options to determine how results are displayed and which features the trace recognizes as barriers.

ArcFM Trace Results Format: Select the format in which you'd like the results to be displayed. You can choose a different size (from 1-50) and color for edge features vs junction features. Select the Auto create selection checkbox to have all features of the trace appear in the Selection tab of the Attribute Editor. Select the Auto zoom to results to automatically zoom out (or in) to the extent of the trace. The Draw Buffer option allows you to add a halo color of your choice to trace with a radius based on the buffer size (1-50).

Select a barrier for the type of trace you will perform:

Pressure System Trace Barriers: 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 Trace Barriers: 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 Trace Barriers: Select Town Border Stations or Regulators to indicate where to stop the trace.

The Temporary Marks section 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.

The remaining tabs are Esri functionality. Refer to ArcGIS for Desktop help for more information.
