Visio 2013: How to reduce width of built-in UML class shape?

Question

I drew a class diagram of the type 'UML static structure' with Visio 2013. Now I would like to reduce the width of the class shapes in the diagram. I removed the size protection in the developer tools section and also tried to set the width in the corresponding shape sheet but nothing worked.
Does someone know how to do this?

Answer 1

In Visio 2013, you can change class width using a control point (yellow dot), just drag it:

Answer 2

The class shape is composed of a group of objects. You should drag your mouse over it to select not only the external shape, but also all the elements inside it such as the ClassName text and any possibly existing members, etc. Now, if you remove the size protection as you mentioned, this will apply to all the elements, and then you can change the size using "Size & Position" task pane. (Ribbon --> View --> Show --> Task Panes)
