 Since Metric_Signal_Value_At_Event outputs all three components, here is a workaround of the previous example that will output one component. Evaluate_Expression is used to create a signal with one component, the z component for **RFT1**. Then the Metric_Signal_Value_At_Event will calculate the value of the TARGET **RFT1** at the Event_Label **RON**. Since Metric_Signal_Value_At_Event outputs all three components, here is a workaround of the previous example that will output one component.
