Free uml diagrams software for mac

Use yEd to quickly create flow charts, UML diagrams, mind maps, and many other kinds of diagrams, graphs and networks.

Choose from a widerange of highly sophisticated layout algorithms to automatically arrange your diagrams in no time.
A intuitive and visually appealing user interface makes creating diagrams fun.
Once you are done with creating a diagram you can save, print or export it to popular formats like WMF, JPEG, GIF, XML, PNG or SVG.

UML implements UML statecharts in C++ and Java. Next to the standard elements of FSMs, hierarchical and concurrent states are as well supported as pseudostates, segmented transitions, timed events and an eventqueue using a thread pool.

Main features:
- Very easy to use API (See documentation for details)
- Implemented in C++ and Java
- Does require only a very small amount of memory
- Complete object-oriented design (all elements are real objects)
- Parallel usage of the statechart infrastructure. Runtime specific data is encapsulated in a small object.
- Support for many elements of statecharts
- Simple, hierarchical and concurrent states
- Start and final states
- History and deep-history pseudostates in hierarchical states
- Fork- and join pseudostates for concurrent states
- Segmented transitions using junction points
- Transitions can cross borders of composite states (implicit entry/exit)
- Entry, do and exit actions in states
- Events, guards and actions for transitions

System requirements:
- Java

Enhancements
- Fixed a ConcurrentModificationException bug when handling timeout events.
- Fixed shutdown procedure when the created threads are non-deamon threads.

Timing Diagram Symbols for Omnigraffle 1.0 is a simple and salutary stencil for Omnigraffle that helps you to draw timing diagrams

Requirements: Mac OS 10.3 or 10.4 Omnigraffle 3.2 or higher

CanvasUML 0.1.1 can be a really useful free Cocoa-based application for Mac OS X Tiger which lends you a helping hand in creating simple UML Class Diagrams. CanvasUML is alpha-quality software and should not be used for mission critical work (as if there were such a thing as mission critical UML diagramming?). CanvasUML is built using Apple's WebKit framework, tag, WebKit's support for ContentEditable.

CanvasUML should be thought of as an exploration of what is possible using the above technologies rather than a solid app. It is basically an experiment to see how far the element can be pushed.

Major Features:

1. CanvasUML is implemented with an unholy mix of HTML, JavaScript, Cocoa, CSS, the tag, contentEditable, and Safari JavaScript Drag n Drop.
2. The main window in a CanvasUML document consists of a WebView (basically like a Safari window) filled by a large, resizable tag. The class/instance boxes are DHTML
   s with nested contentEditable

   s for the title, attribute, and operations sections. The association lines and the shadows behind the class boxes are, of course, drawn by the tag. CanvasUML saves its doucuments as HTML files which link against a shared CSS stylesheet and JavaScript library stored in the CanvasUML app bundle (take a look if you're curious).

Requirements:

• Mac OS X 10.4 Tiger or later.
