To export a class diagram that you created from code in a project, save the diagram as an image. If you want to export UML class diagrams instead, see Export Images of Diagrams.
- Open your class diagram (.cd) file. 
- From the Class Diagram menu or the diagram surface shortcut menu, choose Export Diagram as Image. 
- Select a diagram. 
- Select the format that you want. 
- Choose Export to finish exporting. - To automatically update exported images that are linked from other documents, export the diagram again in Visual Studio.
