123D

Autodesk 123D served as an accessible gateway into the world of 3D design and digital fabrication. Aimed squarely at the hobbyist and educational market, the suite provided a range of tools tailored for ease of use without requiring extensive prior knowledge of complex CAD software.

Key components of the 123D suite included:

• 123D Design: A parametric solid modeling tool that allowed users to create and edit 3D models with intuitive direct manipulation and geometric constraints. It was well-suited for designing functional parts and objects.
• 123D Catch: This application enabled users to create 3D models from a series of photographs, utilizing the power of photogrammetry. It was ideal for digitally capturing real-world objects.
• 123D Sculpt: A digital sculpting tool that provided a more artistic approach to 3D modeling, allowing users to push, pull, and smooth virtual clay to create organic shapes and figures.
• 123D Make: Focused on preparing 3D models for fabrication, particularly for láser cutting and CNC milling, by generating 2D patterns or slice representations of the 3D model.

The suite's integration with Autodesk's cloud services allowed for easy storage and sharing of projects. While no longer actively developed or available for download, 123D played a significant role in democratizing access to 3D design tools, fostering a community of makers and providing a foundational experience for those new to the field.

The Autodesk 123D suite, although discontinued, represented a significant effort to make 3D design and digital fabrication tools accessible to a broader audience beyond professional engineers and designers. Its focus was on hobbyists, students, and small-scale makers, providing a stepping stone into the world of additive and subtractive manufacturing.

User Interface and Ease of Use: One of the primary strengths of the 123D applications was their user interface. They were designed to be approachable and intuitive, particularly the flagship 123D Design software. Unlike more complex CAD packages, the tools and workflows were streamlined, allowing users to quickly grasp the basics of solid modeling. The learning curve was significantly less steep, making it an excellent starting point for those new to 3D design.

Core Functionality: The suite offered a diverse set of capabilities through its different applications:

• 123D Design: This was the heart of the suite for many users. Its parametric and direct modeling capabilities were sufficient for creating a wide range of functional objects, parts, and assemblies. While not as powerful as professional CAD software, it provided essential tools for sketching, extruding, revolving, and modifying solids.
• 123D Catch: This photogrammetry tool was particularly innovative for its time, offering a relatively simple way to create 3D models from photographs. While the results could vary depending on the quality and number of images, it opened up possibilities for capturing real-world objects digitally.
• 123D Sculpt: For users interested in artistic or organic modeling, Sculpt provided a digital clay environment. It offered a different workflow than solid modeling, allowing for more freeform creation.
• 123D Make: This application simplified the process of preparing 3D models for 2D fabrication methods like laser cutting. It automated the generation of interlocking patterns or slices, saving considerable time compared to manual methods.

Integration and File Support: The integration between the 123D applications was generally smooth, facilitated by cloud storage. Standard file formats like STL were supported, ensuring compatibility with 3D printers and other fabrication equipment. The ability to export to various formats also allowed for interoperability with other design software.

Limitations: While suitable for beginners and hobbyists, the 123D suite had limitations compared to professional-grade software. Complex assemblies, advanced surfacing, and sophisticated simulation capabilities were typically not available. Performance could also be a factor with very complex models. Furthermore, the discontinuation of the suite means it is no longer supported or updated, which is a significant drawback for current users.

Overall Assessment: Despite its discontinuation, the Autodesk 123D suite played a vital role in introducing 3D design and digital fabrication to a wide audience. Its ease of use, combined with a range of helpful tools, made it an excellent platform for learning and experimenting. For those who used it during its active life, it provided a solid foundation for understanding 3D workflows and preparing models for physical creation. While no longer a viable option for new users, its legacy lies in its contribution to the maker movement and the democratization of 3D technology.
