Rhino 8 → Rhino 7 compatibility

Downgrading from Rhino 8 to Rhino 7 is one of the smoothest conversions we support. Here's what to expect.

What is preserved

• Layers, block instances, groups
• NURBS surfaces and solids
• Curves, points, meshes
• Materials (basic parameters), textures
• Dimensions, text, annotations

What gets simplified

• SubD: converted to a mesh or NURBS approximation.
• PushPull history: baked in — the parametric history is lost.
• New shaders / PBR extensions: mapped to standard Rhino 7 materials.

Tips before converting

• Bake any parametric geometry you want to keep as static.
• Save a copy of the original .3dm before downgrading, just in case.
• If you rely heavily on SubD, converting to Rhino 6 or older is not recommended.

RhinoFileConverter handles all of the above automatically — just upload and pick your target version.
