When working with Internal Block Diagrams, do not roll up features using the Roll Up, Roll Up Features and Roll Up Contextual Features commands.
To change the type of a block property:
1. Locate the Block Property whose type you want to change. You can use the Parts pane to see Block Properties in context.
2. Right-click the Block Property, point to Set, and then click Type, Type (Redefinition Only) or Type (Top Level Definition):
◦ The Type command is available when the Block Property is not a redefinition.
◦ The Type (Top Level Definition) command is available when the Block Property is a redefinition. The command sets the type of the top-level Block Property.
◦ The Type (Redefinition Only) command is available when the Block Property is a redefinition.
If the Flow Port is a real redefinition, the command sets the type of the Block Property. If the Flow Port is a virtual redefinition, the command sets the type of the Block Property (the real redefinition) on which the virtual redefinition is based.
When changing the type of a redefinition, you cannot create a new type, and you can change the type only to a subtype of the current type.
