How to view a .X3D file online
Three steps, no software to install.
Choose your file
Drag your .X3D file onto the box above. If it comes with companion files like .mtl, .bin or textures, drop them together with it.
It opens right away
Your .X3D file is opened and shown in 3D.
Inspect and measure
Rotate, switch views, toggle wireframe and check size, area and volume before printing.
What is a .X3D file?
Meshes, scenes and what "watertight" means for 3D printing.
An X3D file is an XML document describing a 3D interactive scene: geometry, materials, animation, and behavior. It is the ISO-standardized successor to VRML. Open it with Blender (Web3D X3D/VRML2 add-on), Xj3D, or InstantReality player. The format contains no embedded executables and is safe.

Is my .X3D file uploaded to your server?
No. Your .X3D file is rendered with WebGL.
Why is my OBJ model grey or missing textures?
OBJ keeps materials in a separate .mtl file and textures as images. Select or drop all of them together with the .obj and the viewer will link them up automatically.
How accurate are the volume and weight?
For watertight meshes the volume is exact for the triangles in the file. The weight assumes PLA at 1.24 g/cm³ and 100% infill, so a sliced print with lower infill will weigh less.
My model looks lying on its side. What now?
CAD and 3D-printing files usually treat Z as "up", while games and glTF use Y. Switch Up: Y / Z in the toolbar.
Can I open STEP or IGES files here?
Those are CAD formats that store exact surfaces rather than triangles. Open them in our CAD Viewer, which converts them to a mesh.
