When a model becomes complex, and with many kinematic-chains in each Mechanism-Editor, it becomes more difficult to identify to which kinematic-chain each FB applies.

•You can use Briefcase FBs to hide Function-Blocks from the graphic-area

•You can use different Briefcase FBs to group sets of Function-Blocks.

•You can name the Briefcase FB to help you predict which FBs are 'inside' the Briefcase.

•You can select and edit each Function-Block directly, from inside the Briefcase FB

•You can rename each FBs directly, from inside the Briefcase FB

•You can put a Briefcase FB 'inside' another Briefcase FB, also.

•If you have good naming convention for your FBs, then a Briefcase FB is a good way to help you maintain your model.
