Creating items on an internal block diagram (SysML)
You can create items of the following types on an Internal Block Diagram: Actor, Block Property, Flow Port, Full Port, Proxy Port, Standard Port, Item Flow, Provided Interface and Required Interface.

When working with Internal Block Diagrams, do not roll up features using the Roll Up, Roll Up Features and Roll Up Contextual Features commands.

Alternatively,
1. In an appropriate pane, locate the item that is to type the Block Property.
You can use a Block, Interface Block or Value Type as a type.
2. Drag the item from the appropriate pane to the diagram background, the Block or Block Property in which you want to create the Block Property.
3. If a context menu appears, click New to create a new Block Property.

b. From the Type list, select the type of the item you want to create and use as a type.
c. In the Name box, type the name of the item that will be used as a type, and then click OK.
To create an untyped Proxy Port:
In the Options group, click the Untyped option, and then click OK.
4. From the dialog, select the required direction, and then click OK.
5. Type the required name of the port, and then press the Enter key.
Alternatively,
1. In an appropriate pane, locate the Block (Full Port only) or Interface Block that you want to type the port.
2. Drag the item from the appropriate pane to the edge of the required Block (if shown), Block Property or port on the Internal Block Diagram. When the mouse pointer is over the edge of a Block Property, the mouse pointer appears as follows.
3. From the dialog that prompts you to select the type of port to create, select Flow Port or Proxy Port, and then click OK.
4. Type the name of the Flow Port, and then press the Enter key.
Note that when you create a Flow Port or Proxy Port on a Block Property, the Flow Port or Proxy Port is owned by the containing Block Property's type.
