How to convert 3DM to DXF
- Add your .3DM file - drop it in the box above or click to browse.
- Convert it to .DXF in a few seconds.
- Download your new .DXF file.
What to expect
- DXF is drawing-oriented: NURBS surfaces and solids may be approximated or reduced to wireframe.
- Curves and 2D geometry transfer most reliably; complex 3D detail is where loss occurs.
- Very large or high-version models can produce heavy DXF files that some viewers handle slowly.
Frequently asked questions
How faithful is a 3DM to DXF conversion?
It varies with the content. DXF is primarily a CAD drawing-exchange format, so curves and wireframe transfer well, but complex NURBS surfaces from the 3DM may be approximated or reduced to lower-level geometry.
Why convert 3DM to DXF?
DXF is Autodesk's long-standing neutral exchange format, so it moves Rhino geometry into AutoCAD and many other CAD programs that do not read 3DM directly.
Where can I open the DXF file?
You can open DXF free in LibreCAD, QCAD or ODA Drawings Explorer, or view it in Autodesk Viewer in a browser. ASCII DXF can even be inspected in a text editor.
What does not survive the conversion?
Solid and surface modelling detail. DXF centres on curves and wireframe entities, so 3D surface bodies may be flattened or approximated rather than carried over as editable solids.
