About Using Check Status and Update to Restore Missing Components
You can use the Check Status and Update commands to find and restore the missing part and subassembly components of imported assemblies. Missing TIM components display the broken links icon on the Model Tree.
* 
If you do not use Check Status before you use Update, Creo Parametric informs you that there are no models to update and does not restore the missing components.
You must, therefore, select and right-click a missing TIM component and click Associative Topology Bus > Check Status  before you click Associative Topology Bus > Update. You can also directly click Model > Operations > ATB > Auto Check Status on Update. Auto Check Status on Update or Check Status searches for the source files of the missing TIM components and restores the source files based on the source file names and path stored as the ATB information of the TIMs. ATB restores the source files of the missing TIM components from the directory or folder set as the value of the atb_search_path configuration option. The source files of the missing CADDS 5 TIM components are restored from the location set as the value of the extend_cvpath configuration option or the CVPATH environment variable.
Before you use the Check Status and Update commands or use the Auto Check Status on Update command, you must set the atb_search_path configuration option to point to the location of the source files of the missing TIM part and subassembly components. You can set several instances of this configuration option. Set the extend_cvpath configuration option for CADDS 5 models. You can also locate the missing components and copy them to the import folder before you use the Check Status and Update commands or the Auto Check Status on Update command.
When you use the two-step process of Check Status and Update, the Check Status command locates the source files of the missing TIM components and sets the status of the TIM components as out-of-date. You can then use the Update command to update the out-of-date components. Auto Check Status on Update checks the status of the missing TIM components, sets their status as out-of-date, and updates the components in a single step.

You cannot update legacy Translated Image Models (TIMs) of SolidWorks and NX parts and assemblies in Creo Parametric 3.0. A Check Status of the legacy TIMs that were created in the previous versions of Creo Parametric shows that they are out-of-date. When you attempt to update the out-of-date legacy TIMs in Creo Parametric 3.0, the update fails and results in TIMs with broken links. If you again attempt to check the status of the SolidWorks and NX TIMs that were created in the previous versions of Creo Parametric, a message warns you that you cannot use the translators that are available in the current version of Creo Parametric to update the legacy SolidWorks and NX TIMs. A Change Link does not update such legacy TIMs.
