What is a .3dm file?

3DM is Rhino's OpenNURBS model format for curves, surfaces, solids, layers, blocks, materials, and 3D geometry.

Why is .3dm hard to open on a phone?

  • 3DM parsing usually needs OpenNURBS-compatible tooling.
  • Full geometry, materials, layers, and blocks are too broad for a lightweight first-pass phone preview.
  • A safe header check still helps confirm that the file is a Rhino 3DM candidate.

What OpenOnPhone does not do

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.

MIME examples

  • model/vnd.3dm
  • application/octet-stream

Next steps

  • Choose the 3DM file on the home page.
  • OpenOnPhone checks the local 3DM header and shows file size, header version candidate, and header bytes.
  • Use Rhino, a CAD viewer, or OpenNURBS tooling when you need geometry, layers, materials, blocks, conversion, or editing.
