About Monitoring the Parameters of Analysis Features
You can monitor the parameters created by analysis features in the Performance Monitor dialog box. The Performance Monitor is an asynchronous and modeless dialog box that allows you to monitor the values of parameters of the analysis features, to specify the constraints that those parameters must satisfy, and to verify whether those constraints are satisfied. The dialog box contains a monitoring table with the following columns where you can specify information related to the parameters to be monitored:
• Parameter Monitoring—Specifies whether to monitor a parameter. The check box in this column enables you to switch on or off the monitoring of a specific parameter. If a parameter is not monitored, its status is not updated.
• Model—Displays the name of the model that owns the parameter to be monitored.
• Feature—Displays the name of the analysis feature that computes the parameter.
• Parameter—Displays the parameter to be monitored.
• Value—Displays the current value of the parameter and its units.
• Condition—Displays the mathematical operator of the type <, =, >, >=, or <= selected for the constraint that the parameter must satisfy.
• Reference—Displays the value you specify or the reference parameter you select against which the monitored parameter is compared. The selected reference parameters are assumed to be in the same type of units as the parameter being tracked. For example, if the monitored parameter is measured in meters, then the reference parameter can be in inches. Creo Parametric automatically displays the units for the reference value.
• Tolerance—Displays the tolerance value within which the constraint should be satisfied. You can specify the tolerance as an absolute value or as a percentage of the reference value. To specify the tolerance in percentage, add the % symbol. Tolerance values that you enter are assumed to be in the same type of units as the parameter being tracked unless the % symbol is added. Creo Parametric automatically displays the units for the tolerance value.
• Status—Displays the current status of the constraint. The status indicates whether the parameter satisfies the desired constraint or whether it is updated. There are five possible statues:
◦ 
—The green dot specifies that the constraint is satisfied.
◦ 
—The yellow dot specifies that the constraint is satisfied within the specified tolerance value.
◦ 
—The red dot specifies that the constraint is not satisfied.
◦ 
—The white dot specifies that the constraint is not updated. This status specifies the following conditions:
▪ Constraint is not being monitored.
▪ Analysis feature that computes the parameter is read-only or only regenerates during design studies.
▪ Analysis feature failed to regenerate.
▪ Analysis feature has not regenerated because regeneration of an earlier feature has failed.
◦ 
—The black dot specifies that the constraint is not valid. If either the parameter, or the reference parameter are missing, the constraint is considered to be invalid.
• Warn—Specifies whether a warning should be issued when a constraint is updated and if the status of the constraint is within tolerance, not satisfied, or not valid. The check box in this column enables you to switch on or off the issuing of warnings.
The 3-states button available for each of above listed columns allows you to sort and display all the rows under that column in a particular order. By default, the rows under each column are not sorted in any particular order. Each column can be sorted are as follows:
• 
—Specifies that the rows under the column are sorted in the descending order.
is displayed along with the column name.
• 
—Specifies that the rows under the column are sorted in the ascending order.
is displayed along with the column name.
Auto-Update in the Performance Monitor dialog box allows you to automatically update the status of the constraints when the model is regenerated or when the parameters are modified. If Auto-Update is not selected, you can use Update to evaluate the constraints and update the status.
In the Assembly mode, you can monitor the parameters at all levels within the assembly (top, subassembly, or part). Several models can be monitored simultaneously. However, the
Performance Monitor dialog box corresponding only to the active model is displayed at any time. When a model is being monitored and a different model is activated, the
Performance Monitor dialog box for the initial model collapses into the overall performance status indicator
. The parameters are monitored only if you have selected
Auto-Update, but warnings are not displayed for models that are not active.
The overall performance status indicator
displays the overall status of all the parameters being monitored. It is displayed in the top-right corner in the
Performance Monitor dialog box. The overall status consists of the following three items:
• Status of valid and updated constraints. If all the constraints are satisfied, then the overall performance status indicator
appears in green. If even one of the constraints is within tolerance, then the indicator appears in yellow. If even one of the constraints is not satisfied, then the indicator appears in red.
• Presence of not updated constraints.
• Presence of not valid constraints.
When you click
Close, the
Performance Monitor dialog box collapses into the overall performance status indicator
in the
Creo Parametric status area. If you have selected
Auto-Update before collapsing the dialog box, the monitoring continues and the overall performance status indicator
provides updated status of all the parameters being monitored. If you click twice on the overall performance status indicator
, the
Performance Monitor dialog box is restored.
You can save a setup defined for the selected parameters and their constraints along with the model. The saved setup can easily be retrieved or deleted from the Setup List dialog box.
