You can however move all the items of a diagram with the “Select All” menu option. It is also not possible to move multiple objects at once, so you have to think where you begin your diagram. Having to re-select the item and double-click on it to enter the name is cumbersome if you are drawing a large diagram. I would however complain that the tools lack some simple productivity features, like automatically opening a naming window in the use case diagram when you place a new item. There are Undo and Redo features to quickly modify changes. Selecting and moving items is really straightforward and works fine. You can choose the items to place by either selecting them from the items list visible on the right side of the diagram or with a right-click mouse action. You simply open the type of diagram you want to create and then you position the diagrams items on the screen. Using JetUML is easy with its simple and intuitive interface.

You can define the size of the diagram area and whether or not you will show the tools hints and the grid. There are very few configuration options in JetUML. No specific installation process is required and the size of the application is a just 350Kb On my Windows platform, I just downloaded the jar file and double-clicked on it to open the tool. License & Pricing: Free software, GNU General Public License v3 System requirements: Windows, Mac OS X or Linux with Java Runtime Environment (JRE) Version tested: JetUML version 2.5 in March-April 2020 on a Window 8 platform.

JetUML currently supports the following UML diagrams: class diagrams, sequence diagrams, state diagrams, object diagrams and use case diagrams. The concept of JetUML is to provide the basic support for sketching software design ideas. JetUML is a simple desktop open source Unified Modeling Language (UML) tool UML diagramming.
