About Mass Instances in Design Options, Phases, and Worksets

You can assign mass instances to any workset, range of phases, and design options.

Consider the following limitations:

• If you want to join geometry of 2 masses and then vary the relationships in different options, you must copy both masses into each option.
• If you want to modify relationships between 2 masses and they are in different worksets, either both worksets must be editable, or you will need to borrow one or both of the masses from the owners of their worksets.
• If the relationships between masses vary from phase to phase, you may need to include each mass in each phase.
