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.
