Spin 3D
What it is
Spin 3D converts 3D mesh files between formats for uses 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. The free version is for non-commercial use only. Downloads are offered for Windows 7 to 11 and macOS 10.9 or later; the maker directs Mac, Linux, and Chrome OS users to an online converter. Format support has qualifications: OBJ material files are not yet supported, and some formats are read-only or need an optional component. Converted models can be imported into DreamPlan Home Design Software. Support materials include video tutorials, a help manual, FAQs, a forum, and a technical support contact.
