Do I need Rhino to open 3DM files?

No. The viewer runs in your browser — upload your .3dm and preview, no Rhino license required.

What geometry can I view?

Surfaces, polysurfaces and solids stored in the 3DM file are rendered for inspection.

Yes. Convert 3DM to STEP or glTF once the model looks correct.

Rhino 3DM Viewer中文

Opens .3dm directly in the browser — no software to install.

Open and preview Rhino NURBS models directly in your browser. Inspect 3DM geometry for review and sharing without a Rhino license.

View .3dm files in the browser without Rhino installed.

Inspect surfaces, polysurfaces and solids stored in the 3DM file.

Once confirmed, convert 3DM to STEP or glTF downstream.

When a designer sends a Rhino 3DM file but you have no seat, the online viewer lets you inspect it instantly.

For reviewers without Rhino, the online viewer is the fastest way to check 3DM geometry.

Rhino can hold open surfaces, polysurfaces and solids; the viewer renders what is present.

Confirm the geometry before any conversion.

Viewing confirms the source 3DM model; conversion produces a deliverable.

For engineering CAD, convert 3DM to STEP after reviewing.
