Generating a PDM from an OOM

The Output window shows the progress of the generation process. The new PDM appears in the diagram window.

Updating an existing PDM

There are two ways to update an existing PDM depending on whether the

Preserve Modifications options is selected or not selected:

Preserve Modifications

Selected

Result

You can manually compare and merge existing PDM (target model) with the newly generated PDM ( source model)

Not selected

The existing PDM is automatically replaced by the newly generated PDM

When Preserve Modifications is selected, the Merge Models window appears after the new PDM has been successfully generated. You can use the Merge window to select objects to be updated, deleted, or added to the target model.

The target model must be open in the workspace to be merged with a source model.

You can only generate a PDM from the active OOM diagram window.

The existing PDM, into which you want to generate objects from the OOM, must be open in the workspace.
