Spin 3D converts 3D mesh files between formats for tasks such as 3D printing, game modding, design, and animation. Its product page lists more than 45 supported formats, including OBJ, STL, FBX, BLEND, and GLB as inputs, with OBJ, STL, PLY, 3DS, 3MF, and 3DP among the outputs. Users can preview source models and conversion results, adjust default translation, rotation, and scale values, recalculate normals, and remove duplicate triangles and vertices. Multithreaded batch processing can convert hundreds or thousands of files at once. Downloads are offered for Windows 7 to 11 and macOS 10.9 or above; the maker directs Mac, Linux, and Chrome OS users to its online converter. The free version is for non-commercial use only. Format support has qualifications: OBJ material files are not yet supported, and some formats are read-only or require an optional component. Converted models can be imported into DreamPlan Home Design Software. Help options include video tutorials, a manual, FAQs, a forum, and a technical support contact.
