Manipulist 3DViewer is an online viewer for 3D files in STL and X3D format. It is absolutely privacy-safe as we don't store any data in our database. Upload the file, zoom/pan/rotate and see it from 6 different sides. PRO users can export screenshots, get the main dimensions of the object and enjoy real-time collaboration . Dimensions are unit-agnostic, you have to be aware of the model's unit of measure. Do you need a quick preview of your 3D files? Manipulist 3DViewer is the tool you need!
