It is represented by a dashed arrow in the direction of the included use case with the notation >. You can also scroll diagram by dragging with mouse middle button (wheel button). Typically mouse wheel scrolls vertical and mouse wheel with Shift key scrolls horizontal. Include relationship: The use case is mandatory and part of the base use case. You can scroll diagram by typical mouse wheel or touch pad scroll gestures. It is represented by a dashed arrow in the direction of the base use case with the notation >. To represent complex relationships between different use cases, we can use the extend and include relationships.Įxtend relationship: The use case is optional and comes after the base use case. SYSML support: StarUML supports modeling with SYSML diagrams such as Objects, Use Case, Class, Sequence, Deployment, Activity, Timing diagram, and others. The use cases are functions performed by the actors interacting with the system. The actors are users or systems that interact with the main system and are represented by figures. The system is represented by a box encompassing the use cases. The use case diagram displays three kinds of entities: the system, the actors, and the use cases. A use case diagram can be made for a general scenario or multiple scenarios that encapsulate the system’s functioning. You can follow the instructions here in order to set your own PlantUML server up.A UML use case diagram summarizes the interactions between a system and its users. Use the 'Server' button to enter a URL to a different PlantUML server in order to make it work or speed it up. If diagrams are not refreshing quickly or not at all, the PlantUML server may be slow or completely down.You can switch to VIM or Emacs mode if you are an old school unix geek. The 'Settings' buttons contains user settings that affect the way the editor works and it's appearance.Be careful though because importing will copy the PlantUML in those files over any PlantUML you already have in the PlantText editor. Use the 'Files' button to quickly export and import PlantUML as text files to and from your local file system.These PlantUML diagrams are grouped by diagram type and follow a natural progression. A quick way to learn PlantUML is by working through the sample dropdown list.This way you don't have to use your mouse to refresh at all. Press the Alt + Enter keystroke combination to refresh the PlantUML diagram.It allows you to focus on the relationships and complex ideas you need to capture in your design, rather than endlessly resizing and aligning rectangles. You could even parse the text programmatically with other tools like NPlant.ģ. The diagrams are based on ASCII, so you can use your own source control software to version and perform diffs on them. Once you learn the basics of the syntax, you can generate UML diagrams much more quickly than with a typical drag and drop tools.Ģ. PlantText and PlantUML support most standard UML diagram types as well as many other diagram types like GraphViz, Salt, ASCII Art, and XEarth. The Object Modeling Group currently maintains and promotes UML. UML (Unified Modeling Language) is a standard language for designing software modeling diagrams. See the PlantUML website for more information on the development of the language. Use the samples provided or download this ebook to learn more. PlantUML is a flexible language that is intuitive to learn and easy to master. Simply type PlantUML into the editor and refresh the screen to produce a professional, clear diagram. With PlantText, software architects can create UML diagrams using a simple language without being distracted by aesthetic details or the use of a mouse. We want to hear what you like about PlantText and what new features you’d like to see. Please tell your friends about the tool and provide feedback here. We are very grateful for the support of the software development community in the form of feedback and help promoting it. Donations are greatly appreciated to help cover the costs of hosting, maintenance, and enhancements. PlantText is currently free to use for commercial and non-commercial purposes. Save, export, or copy the image or it's encoded link for use in your websites, requirements, or design documents. Simply type the PlantUML language into the editor and refresh the screen to produce the image / diagram. It is mostly used to create UML diagrams (Unified Modeling Language) from a language called PlantUML, but many other types of images and diagrams can be created as well. PlantText is an online tool that quickly generates images and diagrams from the text you enter.
