Therefore, you can use the following ATB commands to establish the links between the missing source files and the empty TIM parts and subassemblies and restore the missing components:

You must, therefore, select a missing TIM component and click Model > Operations > ATB > Check Status and then click Model > Operations > ATB > Update or directly click Model > Operations > ATB > Auto Check Status on Update. You can, alternatively, right-click the TIM and click Associative Topology Bus > Check Status and then click Associative Topology Bus > Update.

ATB updates the missing TIM components only when it finds the source files of the missing TIM components. When you check the status of the TIMs, 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 ATB information stored with the TIMs that includes the source file names and path. Auto Check Status on Update or Check Status searches and 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. You must, therefore, use the atb_search_path configuration option to add the location of the source files of the missing TIM components to the ATB search path before you use the ATB commands to check status and update the missing TIM components. For CADDS 5 models, the source files are restored from the location set as the value of the extend_cvpath configuration option or the CVPATH environment variable. When the Check Status command restores the source files of the missing TIM components, the missing TIM parts and assemblies show the out-of-date status. You can use the Associative Topology Bus > Update command to update the TIM components. The Model > Operations > ATB > Auto Check Status on Update command automatically checks the status of the TIM components before it updates the TIM components.
