I'm doing UML class diagram in Visio 2007. My automatically created root UML system has several predefined data types, such as C# Data Types, C++ Data Types, etc. I'm modeling C++ program so I need no C# data types. However, every time I'm to select type of some parameter I have a long list of predefined C# types and only after those I can see C++ types, which I'm only interested in.
So is there a way to disable annoying C# data types in this list? I cannot delete it or rename it or even adjust any property. Thanks for your help.
