Partstep

Partstep is an open-source, web-based platform designed to facilitate the creation and sharing of interactive 3D models, particularly focusing on parametric and generative design. It allows users to design and manipulate 3D objects using a browser-based interface, eliminating the need for traditional CAD (Computer-Aided Design) software. The platform is built on top of the OpenSCAD programming language, which enables users to define shapes using a script-like syntax, making it accessible to those with programming experience while still offering a visual workflow.

Developed as a community-driven project, Partstep emphasizes collaboration and sharing, allowing designers to upload, modify, and remix 3D models. The platform supports features such as version control, real-time collaboration, and cloud-based storage, making it suitable for both individual creators and teams. It also integrates with popular 3D printing services, enabling users to directly export their designs for manufacturing.

Partstep is particularly useful for parametric design, where models are defined by variables and constraints, allowing for easy iteration and customization. This makes it a valuable tool for prototyping, educational purposes, and open-source hardware projects. The platform is free to use, with optional contributions supporting its continued development.

While Partstep is primarily browser-based, it also offers a desktop application for offline use, ensuring flexibility for users with varying needs. The project is actively maintained by a community of developers and designers, with ongoing improvements aimed at enhancing usability and expanding functionality.
