What is 3DM?

3DM is the native file of Rhino, used widely in industrial, jewellery and architectural design. It stores NURBS surfaces, SubD objects, meshes and block instances.

Full name
Rhinoceros 3D model (openNURBS)
Type
Exact CAD geometry
Used in
Rhino, Grasshopper, KeyShot, Blender (with add-on)
Strength
Rich surface modelling data from Rhino.
Limits
Surfaces are converted using the render meshes Rhino saves in the file.

What is DXF?

DXF is AutoCAD's exchange format. We write your model as 3D faces that AutoCAD, LibreCAD and most CAD programs can open.

Full name
AutoCAD Drawing Exchange Format
Type
Triangle mesh
Used in
AutoCAD, LibreCAD, DraftSight, laser and CNC software
Strength
Opens in AutoCAD-compatible software.
Limits
3D faces only; not a solid model.

Good to know

Rhino saves a display mesh for every surface it has shown in shaded view. We use those meshes. If a file was saved with "Save Small", open it in Rhino, switch to shaded view and save it again.

Questions

Are materials and textures kept?

Colours and texture coordinates are carried over when DXF supports them. DXF does not store textures, so only the geometry carries over.

Will my model be upside down?

No. 3DM and DXF may use different "up" directions, and we rotate the model so it stands the same way in your software.

Are my files uploaded?

No. The conversion runs inside your browser.
