You can optionally choose to always add Eclipse projects to Dimensions CM as contained projects, by default. You can then optionally override this default when adding Eclipse projects to Dimensions CM.
To set the default project type:
Select Window | Preferences.
Expand the Team | Dimensions CM node.
If you will work with project containers, select the Show Eclipse Project Containers in Explorer check-box.
To default to creating contained projects when you add Eclipse projects to Dimensions CM, select the Default project creation in Eclipse Project Container check-box.
