About Flexibility on the Fly and Instrumented Assemblies
To maintain integrity of the source component, flexible components with the required varied items are automatically created to accommodate changes. The term for this is Flexibility-on-the-fly. Flexibility is created when you edit dimensions of a component, edit placement constraints, change the material, and so on.
When you redefine a component’s placement, the component now has an alternative definition. The Alternative Definition check box is selected in the Varied Items dialog box. When you clear this check box, the component reverts to the placement definition in the source model.
You cannot change the placement of sensors that were inserted in the source model.
With Flexibility-on-the-fly you can work in the native Creo Parametric environment to perform operations. Flexible components with varied items are created in the background. By using varied items for changes, the source model of the component remains unchanged. In Instrumented Assemblies, flexibility is applied to sensor owners with the sensor parameter values becoming the varied items. Each instance of a sensor placed in the model can have different values for a parameter.
To automatically define flexibility on-the-fly to multiple occurrences of sensors in subassemblies, use one of the following options:
In the Creo Parametric Options dialog box Assembly page, set the Automatic flexibility for lower-level Sensors setting to yes.
Set the auto_flex_lower_sensors configuration option to yes.
You can set these options to prompt to be prompted to set flexibility for each occurrence of a sensor.
To allow smooth and risk-free work, operations that do not support flexible components are unavailable. These include activating a component in an instrumented assembly and creating varied items for components driven by Pro/Program.
