Generating a CDM from an OOM

Generating a CDM from an OOM

You can generate a CDM from a global OOM or from a package within the model. Limiting CDM generation to a single package is useful when different designers own packages of the same OOM. Designers can generate their packages independently from others. Generating a package results in an independent CDM.

You generate a CDM from a diagram in the model.

You can generate a CDM in two ways:

Generate

New CDM

Updated CDM

Description

Creates a new (default) CDM containing the objects translated from the OOM

Creates a default CDM containing the objects translated from the OOM that is then merged with an existing CDM. You can choose to update, delete; or add objects in the existing CDM (target model) based on modifications made in the default CDM (source model)

For more information on merging two CDM, see the chapter Comparing and Merging Models in the PowerDesigner General Features Guide.
