What is an IBD used to specify? - The internal structure of a single block. What is an IBD? - A static (structural) view of the system or one of its parts. What is a major limitation of IBD's in SysML? - SysML offers no means to model the geometry of your system. When should you use and BDD and when should you use IBD? - Use a BDD to define a block and its properties. Use an IBD to display a valid configuration of that block. What is the only allowable model element type for an IBD? - A Block. The frame of an IBD always represents a block that I've defined somewhere in my system model.

What must happen if a connector type is specified? - The connector type must be the name of an association created between two blocks somewhere in the model. What does conjugated (~) mean? - That the direction of the flow properties in the flow specification are reversed for that port.What is being conveyed when a part property is connected to a port on the frame of an IBD? - This conveys that an instance of the composite structure can pass requests for behaviors and item flows either from external clients to that internal part or from that internal part to external providers. What is an item flow? - An item flow represents a type of matter, energy, or data that flows between two structure within a system
