I'd like to announce the release of Trace Modeler v1.0, an easy-to-use and smart UML sequence diagram editor.
It combines the immediate and automatic layout of UML sequence diagrams with a simple drag and drop interface. And it's cross-platform to boot.
Here's a 30 sec demo of Trace Modeler in action
It can be used by any development team for brainstorming and prototyping the design of new systems, or for the documentation of existing ones.
Sequence diagrams are notorious for their rigid layout constraints. Even a simple design change can require a complex rearrangement of diagram elements. Surprisingly, most developers can expect little help from their UML tool in this matter. They're forced to express their design ideas using low-level shape manipulations and have to (re)layout their diagram manually whenever they change it. Not only is this tedious and a waste of their time, it also distracts from the task at hand.
Trace Modeler grew out of a personal itch that needed scratching : I have to draw a lot of sequence diagrams and got a bit frustrated that is was such a drag. So I rolled my own in an attempt to optimize developer productivity when working with UML sequence diagrams.
It's main benefit is that it can save you a tremendous amount of time. It instantly updates a diagram's layout whenever it changes, freeing
you to focus on the actual content. Furthermore, its layout engine ensures that every diagram is visually pleasing and structurally correct.
At the heart of it lies an understanding of the flow of control in sequence diagrams. This domain knowledge is used not only to determine the proper diagram layout, but also to interpret user actions. This enables you to quickly change a diagram with simple drag and drop gestures, whilst Trace Modeler maintains its correctness and pleasing layout.
As a result, ideas can be expressed almost instantly with Trace Modeler.
The visual appearance of a diagram is controlled by a handful of style settings. These enable you to give it a consistent look with just a few clicks. Here's a gallery of UML sequence diagrams
to demonstrate these style settings.
Trace Modeler also offers a couple of unique features
- splitting activations
- inlining message calls
- smart flow-based comment connectors
- right-to-left diagram layout and full bidi-text support for non-Western scripts
- automatic object lifetimes
- control flow highlighting
Diagrams are stored in a simple and readable text-based file format, ideal for versioning systems and file comparison tools. This format makes it easy to generate sequence diagrams with other tools or from running code, and visualize them with Trace Modeler. Diagrams can be exported to various popular graphics formats and the clipboard. It also offers a batch export feature that can be used from the command-line for easy integration into any automated documentation process.
Trace Modeler is extremely portable: it works on all major platforms, requires no installation and has very accommodating license terms.
A free, fully functional evaluation version is available for download
for downloads, online demos and other UML sequence diagram resources.
But what about you? How often do you use sequence diagrams in your daily work and what for? Do you feel you're being productive with your current tool? What neat features would you like to see added to tools that support these diagrams?
I'm always looking forward to feedback, especially on the unique features described above or any others you can think of!
Thanks for your time!
