HeeksCAD

HeeksCAD is a free and open-source, parametric 3D CAD (Computer-Aided Design) application. It is designed for creating solid models and assemblies. HeeksCAD is known for its relatively small size and simplicity compared to some other CAD software packages, while still offering a good range of functionality for basic to intermediate design tasks.

Key features of HeeksCAD include:

• Parametric Modeling: Objects can be defined by parameters, allowing for easy modification and design changes. Altering a parameter updates the entire model accordingly.
• Sketch-Based Design: Creation of 3D models typically begins with 2D sketches, which are then extruded, revolved, or otherwise transformed into 3D shapes.
• Solid Modeling: HeeksCAD creates solid models, which accurately represent the volume and material properties of the designed object.
• Open Source: Being open source, HeeksCAD is free to use and distribute, and its source code is available for modification and improvement. This fosters community development and allows users to customize the software to their specific needs.
• Cross-Platform: HeeksCAD is designed to run on multiple operating systems, including Windows and Linux.
• Extensibility: The software can be extended through plugins and scripts, allowing users to add custom features and functionality.

HeeksCAD aims to provide a user-friendly environment for creating 3D models and is often used by hobbyists, students, and small businesses involved in product design, engineering, and manufacturing. While it may not have all the advanced features of high-end commercial CAD systems, it offers a solid foundation for learning CAD principles and creating practical designs.
