====== Metric Explicit ======

This command creates a metric signal explicitly.

<code>
Metric_Explicit
/RESULT_METRIC_NAME=              Name of the resulting signal
! /RESULT_METRIC_FOLDER=PROCESSED Name of the resulting folder
/METRIC_VALUE=                    Component Value(s);
</code>

Previous versions of Visual3D labeled this command Explicit_Metric

===== Example =====

This example will create a metric signal with 3 component values of 1, 2, 3. The resulting signal will be named **NEW_SIGNAL** and be located in the **OFFSET** folder.

<code>
Metric_Explicit
/RESULT_METRIC_NAME= NEW_SIGNAL
/RESULT_METRIC_FOLDER= OFFSET
/METRIC_VALUE= 1+2+3;
</code>

==== Result ====

{{:Event_Explicit_exampleresult.jpg}}

==== Expressions ====

In early implementations of this command the values in Metric_Value were a list of components you wanted the metric explicitly set to (see example above), and expressions were not allowed.

In version 6 Metric_Value can be an expression, but this may lead to some confusion.

For example,

<code>
Metric_Explicit
! /RESULT_METRIC_FOLDER=PROCESSED
/RESULT_METRIC_NAME=X
/METRIC_VALUE=1
;
</code>

<code>
Metric_Explicit
! /RESULT_METRIC_FOLDER=PROCESSED
/RESULT_METRIC_NAME=TEST
/METRIC_VALUE=METRIC::PROCESSED::X+1
;
</code>

The processing results for the second command are:

Metric Name : METRIC::PROCESSED::TEST\\
Metric Expression : VECTOR(METRIC::PROCESSED::X,1)\\
Metric Value : 1.000000 , 1.000000 ;\\
The second command be re-written as follows:

Metric_Explicit\\
! /RESULT_METRIC_FOLDER=PROCESSED\\
/RESULT_METRIC_NAME=TEST\\
/METRIC_VALUE=[[Visual3D:Documentation:Pipeline:Expressions:Expressions_Overview#Pipeline_parameters_using_.2B_as_delimiter|Add]](METRIC::PROCESSED::X,1)\\
;\\

The processing results for the third command are:

Metric Name : METRIC::PROCESSED::TEST\\
Metric Expression : Add(METRIC::PROCESSED::X,1)\\
Metric Value : 2.000000 ;\\
