NClass 1.6

NClass is an open-source UML class design tool created by Balazs Tihanyi. It allows users to create and edit designs of software systems using the Unified Modeling Language (UML) without writing any code.

The tool has a user-friendly interface that includes basic functionalities such as drag and drop, copy and paste, undo, and redo. Users can create different types of diagrams including use case diagrams, class diagrams, activity diagrams, and sequence diagrams. NClass also provides the ability to export diagrams in various formats such as PNG, JPEG, BMP, and SVG.

• Use case diagrams: these diagrams represent the functionality of a system from the perspective of external users.
• Class diagrams: these diagrams show the class structure of a system, its attributes and methods, and the relationships between them.
• Activity diagrams: these diagrams show the flow of activities in a system.
• Sequence diagrams: these diagrams show the interaction between objects in a system over time.

NClass is written in C# programming language and runs on the .NET framework. It is available under the GNU General Public License, which means users can modify and distribute it freely under certain conditions.

The tool is suitable for developers, system analysts, and students who want to create software systems using UML without writing code. It supports Windows operating systems only.
