The Merge Bundle command allows the user to merge two separate bundles into one bundle. For example, if there were two bundles connected to an enclosure, and the enclosure needed to be deleted, you would use the 'Merge Bundle' command to accomplish this task. The Merge Bundle command will combine two selected bundles, using the components of the first bundle selected to form the 'new' bundle.

From the Modify/Delete section of the Duct Tab select the Merge Bundle command:

The user will then be prompted to select the first duct bundle to be merged. (The components of this bundle will be used to determine the components of the merged bundle.)

After selecting the first bundle, the user will be prompted to select the second bundle to be merged. After selecting the second bundle, the merge is completed.
