        throws InvalidUsingException, ClassNotFoundException {
    ProjectAccessor projectAccessor =  AstahAPI.getAstahAPI().getProjectAccessor();
    ClassDiagramEditor cde = projectAccessor.getDiagramEditorFactory().getClassDiagramEditor();
    try {
        TransactionManager.beginTransaction();
        IDiagram iClassDiagram = cde.createClassDiagram(project, diagramName);
        TransactionManager.endTransaction();
        return iClassDiagram;
    } catch (InvalidEditingException e) {
        e.printStackTrace();
        TransactionManager.abortTransaction();
    }
}
