NClass

NClass is a lightweight software application designed specifically for helping you create UML class diagrams while offering support for C# and Java language specific elements.

Although there’s no support for a help manual that could give you more details about the function of each dedicated parameter, the layout looks user friendly and clean. You can rely on tooltips for viewing short descriptions of the supported functions.

The tool integrates a multi-tabbed environment where you can work with different projects at the same time. Pus, you can easily switch between them and save them for future editing tasks.

A project is used for storing data about the UML class diagrams, and you can create a new one by entering a name. The app lists all your projects in the main window.

NClass gives you the possibility to create diagrams with the aid of various objects, such as class, interface, enum and comment, which are syntactically and semantically verified.

You can insert various types of connectors in order to link the objects, such as association, composition, aggregation, generalization, and dependency, work with class editors with syntactic parsers, and perform reverse engineering from .NET assemblies.

What’s more, you can make use of the drag-and-drop support for moving objects from a position to another, zoom in or out of the diagram, cut, copy, paste or delete components, automatically adjust an object in terms of size, width or height, import .NET assemblies (EXE or DLL file format) and close all documents with a single click.

NClass is able to create code for C# and Java, and lets you pick the destination where the source code is saved, as well as print or save the diagram to BMP, GIF, JPG, PNG or EMF file format.

Advanced users may tweak several parameters in order to alter the diagram in terms of attribute color, background color, border color, shadow and border width for several components.

NClass comes with a decent feature pack and intuitive GUI for helping you create UML class diagrams with C# and Java language support.
