Help! I have a question about the package in the class diagram. I use command pattern in the design. So I have many concrete command classes. If I draw all of them in the class diagram, the diagram will be so messy, I'd like to package them and only draw a package in the class diagram. Is it ok? And when I submit the assignment, I have to show two class diagrams, will it be fit to the requirement of the assingment? And I want to know some advice on how to do it!
