The final step to manage and share your solid models is to share them online. This can help you showcase your work, get feedback, find inspiration, and join a community of fellow solid modelers. There are numerous platforms and services, such as Thingiverse, GrabCAD, Sketchfab, and Shapeways, that allow you to upload, view, and download solid models. Each platform has its own features and benefits depending on the type of models you want to share and the audience you want to reach. For example, Thingiverse is a popular platform for sharing 3D printable models, GrabCAD is a professional platform for sharing CAD models, Sketchfab is a platform for sharing 3D models with interactive and immersive features, and Shapeways is a platform for selling 3D printed products. To ensure success when sharing your models online, you should choose a platform that suits your goals and preferences; convert your models to the appropriate file format; add relevant information and metadata such as title, description, tags, license; optimize your models for performance and quality by reducing the file size or simplifying the geometry; and engage with other users by responding to comments or questions.
