Subsequent costing and costing with scenarios
When you open a component that has been costed before, aPriori Desktop displays the saved cost information for the component on the Cost Object window. To display this window or edit production, administrative, or quote information, select Production Info, Administrative Info, or Quoted Cost from the Edit menu on the Manufacturing Process panel.
aPriori provides several ways to update costing as a component changes:
• auto-costing – Depending on a number of factors and settings described below, aPriori can sense when an object’s CAD information has changed and automatically recost the component
• Cost buttons (
) – aPriori provides Cost buttons at various places throughout the interface. Click this button when you want to manually initiate a costing operation.

Click this button when you want to manually initiate a costing operation.• The Cost menu – This menu exists in the aPriori menu bar and provides advanced costing options such as costing multiple component scenarios and “deep” costing of children components within assemblies.
You can define different scenarios for parts, assemblies, cost comparisons, and roll-ups, and explore the impact of different inputs on the cost of a component. A part or assembly’s initial scenario is the official scenario by default. You can specify another scenario to be official. The official scenario is the default scenario to roll into an assembly depending on the setting of the Tools > User Preferences > Use Official Scenarios in New Assemblies, and if a specific scenario is not otherwise specified. This is the one that is costed when you perform a “deep cost” operation (Cost> Deep Cost Scenario & Children). This allows you to select a specific component scenario to roll into an assembly or to use the designated official scenario in a specific assembly. In the latter case, changing which scenario of a component is designated as official will result in changing which scenario rolls into the assembly. Only one component scenario may be designated "Official". You can use the right-click Switch Scenario feature in the Assembly Details view to choose another scenario for child components other than the official one. (Note that subcomponents must be initialized before you can switch scenarios.) You can cost all child scenarios, both official and non-official, by clicking Cost> Deep Cost All Scenarios. See Working with scenarios on page 1 for more information.
Note: When you specify that the official scenario of a sub-component is to be used, the Assembly Details display will show that component with parentheses around the scenario name. In the following screenshot, both AP_SHEETMTL_EXERCISE_EL0000 (which has a new scenario that is official) and WELD_SUPPORT_EL0000 (whose original "initial" scenario is official) have been specified to use their official scenarios.
Unless a scenario has been set to “Inactive”, CAD changes to a CAD-connected part will be automatically picked up when the scenario is costed. However, if no CAD changes have occurred since the last costing, aPriori will not refresh GCDs in subsequent costings, even if the component is CAD-connected and set to “active”. To refresh GCDs for an inactive scenario you can either:
• Click the Refresh GCDs button (
) on the aPriori toolbar.
) on the aPriori toolbar.• Select Refresh GCDs from CAD Model from the right-click context menu in the Navigation pane.
Subsequent costing in CAD Independent mode if the component is file-connected
aPriori checks the CAD-file for GCD changes done since the current cost was saved. aPriori can only detect the changes that have been saved into the CAD-file.
If aPriori detects no changes in the CAD file, the current costing information is displayed. The 
icon in the Cost Outputs pane indicates that the cost is current.

• Off: aPriori immediately costs the component and displays the new cost information. (Disabling One Click Costing is the same as enabling auto-costing.)
• On: aPriori displays the existing cost information, but the Cost Outputs pane is disabled and the

aPriori has no way to detect GCD changes. The cost information is displayed as current. You are not allowed to perform any operations that require regenerating GCDs.
Subsequent costing in Direct Integration mode
aPriori checks the CAD system for GCD changes done since the current cost was saved.
If aPriori detects no GCD changes, the current costing information is displayed. The icon in the Cost Outputs pane indicates that the cost is current.
