Questions about the 3D viewer
Which formats can I open?
STEP, GLB, glTF, STL, OBJ and PLY. For glTF, select the referenced BIN and texture files as well. OBJ is shown as geometry without MTL materials. STEP/STP is supported; native Blender files are not supported.
Are my files uploaded?
Model files are read locally in your browser. No account or credits are required. External model resources are blocked; include companion files in your selection.
Can this viewer check whether a model is printable?
It helps you inspect geometry visually, but does not validate watertightness, wall thickness or printability. Check those in your slicer.
