![]() But the enforced existence of this model and the UI constraints that come with it are such that it makes it so difficult to create the diagram I want that it utterly defeats the point. ![]() In the case of a class diagram I might want to generate some code (although that's unlikely). I'm doing this task because I want the diagram, I don't care whether the tool that created the diagram maintains some notion of a model associated with that. Of what value to me is this in my face representation of a model when all I want to do is create a flowchart or a class diagram? It doesn't give me any benefit. I learn that this is another one of those tools that insists on having this in your face notion of a 'model' associated with every diagram, and that as a consequence of this decision every tiny little task is going to be either 10 times harder than it needs to be, or will just be impossible. 'Views in clipboard cannot be pasted in this diagram'. I want it to be the same size as the existing element, so rather than creating one the default size and having to adjust it, I try to copy the existing process element that is already the size I want. Now I want to create another process element. It supports activity diagrams, component diagrams, class diagrams, sequence diagrams, and use case diagrams, but not communication diagrams or state diagrams. Then I enter some text and resize the element it to make it look right. Because I couldn't drag it on, I didn't get a preview of where it would end up, so I also had to adjust its initial position after I created it. ![]() I couldn't just drag it on the drawing canvas, I had to first click it on the tool palette, then click somewhere on the canvas. IntelliJ IDEA will update the source code accordingly.I create one process element. To delete the existing links, select the ones you don't need and press Delete. You can select the icon on the diagram toolbar to draw relationship links between elements in your graph. You can view members of the class, add new, delete the existing ones, see implementations, check parent classes, perform basic refactoring, add notes, and so on. When working with diagrams, use the context menu in the diagram editor to perform different tasks. To save the diagram as a file, right-click the diagram editor and from the context menu, select Export Diagram | Export to File and then the file extension in which you want to save the diagram. This might be helpful, when you generate a diagram on a package that contains inner packages. When you click through classes in the graph, IntelliJ IDEA greys out classes that do not reside in the same package. Select Tools > Code > Instant Reverse Java to Sequence Diagram from the toolbar. IntelliJ IDEA follows the UML conventions in showing relationships between the classes. In the Instant Reverse window, add the zip file of source or folder path of source by clicking on the appropriate Add button at the right hand side of the window. You can click the icon to see class dependencies. The protected methods are displayed with modifier icons next to them. IntelliJ IDEA displays members with visibility not less than protected, such as public, package local, and protected ones. For example, to view protected methods, click on the diagram toolbar and select protected from the list. The lists are displayed based on the selected visibility level, which you can change. To see the list of methods, fields, and other code elements, select the appropriate icon on the diagram toolbar located on top of the diagram editor. You can press Ctrl+F12 on the element to view a list of diagram elements and navigate between them. Select VCS | Uncommitted Changes| Show Local Changes as UML Ctrl+Alt+Shift+D. You can view your VCS local changes as a diagram. IntelliJ IDEA generates a UML diagram for classes and their dependencies. In the list that opens, select Java Class Diagram. In the Project tool window, right-click a package for which you want to create a diagram and select Diagrams | Show Diagram Ctrl+Alt+Shift+U). Such diagrams always reflect the structure of actual classes and methods in your application. IntelliJ IDEA lets you generate a diagram on a package in your project. Open the Installed tab, find the Diagrams plugin, and select the checkbox next to the plugin name. Press Ctrl+Alt+S to open the IDE settings and select Plugins. If the relevant features aren't available, make sure that you didn't disable the plugin. This functionality relies on the Diagrams plugin, which is bundled and enabled in IntelliJ IDEA by default.
