Saving and Restoring the Initial State 

This procedure describes how to save and restore a simulation to its initial state.  

A simulation's initial state is a consistent state of the world, which is used as the starting point of the simulation, and from which the simulation will always begin.  The products, resources, FTAs (associated with CATPart, CATProduct, and CATProcess files) or 3D Annotations that are part of a simulation do not have an initial state defined until they are used as part of a simulation activity command.  Once they are used as part of a simulation activity command, their initial state becomes what it was before the simulation command acted upon them.  The simulation activity commands are those defined in the Simulation and the Simulation Activity Creation toolbars. In this sense, V5 automatically saves an initial state for all processes.  Using Save Initial State , you can save the initial state of the products, resources, FTAs, and 3D Annotations before a simulation activity command is introduced into the process; using Restore Initial State , you can restore the initial state to the products, resources, FTAs and 3D Annotations.

This procedure has two parts: 
The selection mode affects the behavior of Restore Initial State and Save Initial State . See the selection mode procedure for more information.

Save the Initial State

Before starting this procedure, verify that your simulation is in its initial state.  Keep in mind that you can alter the initial state of the simulation beyond repair.  It is very important to understand the significance of the initial state as well as the consequences that result from altering it.
 
  1. Click Save Initial State .

    The Save Initial Condition dialog box appears.
  2. Do you want to save all of the products and resources as part of the initial state?

    • If YES, you want all products and resources saved, go to Step 4.
        
    • If NO, you want only some of the products and resources saved, go to Step 3
  3. (Optional) In the dialog box, choose Selected Products/Resources only, then on the geometry or PPR tree, select the required products, resources, FTAs (associated with CATPart, CATProduct, and CATProcess files) or 3D Annotations desired.

    When you choose Selected Products/Resources only, a counter appears.
    As you select products, the selected products are highlighted and the counter increases.  If a selected product is selected again, it is removed from the selection: selection acts as a toggle.
  4. Do you want to save all of the attributes as part of the initial state?

    • If YES, you want all initial state attributes saved, go to Step 6.
        
    • If NO, you only want some of the initial state attributes saved,  go to Step 5
  5. (Optional) Choose Selected Attributes; then select an attribute.

    To select multiple attributes, use the LMB+Ctrl.
  6. Click OK. 

    A status window appears telling you what percentage of the save is complete and how many seconds are remaining.
    Once the status window disappears, the initial state is saved.

Restore Initial State

 
  1. Click Restore Initial State .

    The Restore Initial Condition dialog box appears.
  2. Do you want to restore all of the products, resources, FTAs, and 3D Annotations to their initial state?

    • If YES, you want all products and resources restored, go to Step 4.
    • If NO, you only want some of the products and resources restored, go to Step 3
  3. (Optional) In the dialog box, choose Selected Products/Resources only, then on the geometry or PPR tree, select the required products, resources, FTAs, and 3D Annotations.

    When you choose Selected Products/Resources only, a counter appears.

    As you select products, the selected products are highlighted and the counter increases.  If a selected product is selected again, it is removed from the selection: selection acts as a toggle.
  4. Do you want to restore all attributes to their initial state?

    • If YES, you want all attributes restored, go to Step 6.
    • If NO, you only want some of the attributes restored, go to Step 5
  5. (Optional) Choose Selected Attributes; then select an attribute.

    To select multiple attributes, use the LMB+Ctrl.

  6. Click OK. 

    A status window appears telling you what percentage of the restoration is complete and how many seconds are remaining.

    Once the status window disappears, the initial state is restored.
The products that are not used in the simulation do not have their initial state restored when using Process Simulation (for performance reasons.) Still, it is possible to restore their initial state using the Restore Initial State (with the All Products and Resources option selected).
