Hey there, 3D enthusiasts! Have you ever wondered what file types 3D viewers support? Let's dive into it. 3D viewers typically support a variety of file formats, including OBJ, STL, PLY, and FBX. These formats are commonly used for 3D models and are compatible with most 3D viewers. Additionally, some 3D viewers can also handle other file types such as DXF, 3DS, and IGES. It's important to note that not all 3D viewers support every file type, so it's essential to check the specific supported formats of the viewer you're using. So, whether you're working with CAD designs, 3D scans, or gaming assets, rest assured that there's a 3D viewer out there that can accommodate your file type. Keep creating and exploring in 3D!
