Why we like it

Earns its place in the superhive library as a single-format .3dm bridge that keeps Blender lightweight by offloading conversion to a cloud service. Worth noting the round trip goes through mesh, so NURBS accuracy, procedural shaders and animation don't survive it — the add-on is aimed at Blender-side rendering rather than NURBS-accurate exchange.

What is Super3D Import & Export .3Dm?

Super3D Import & Export .3Dm is a Blender add-on from shouwang that bridges Rhino's native .3dm scene format with Blender. It adds dedicated entries to Blender's File menu for importing and exporting .3dm files, and handles format conversion through the Super3D cloud service rather than on the local machine. Because that conversion runs in the cloud, no Rhinoceros license is required — you only need Blender and an internet connection.

On import, the add-on uploads a chosen .3dm file, then downloads and merges the result into the active scene. Visible polysurfaces and meshes are tessellated to Blender geometry, layer names are preserved as object or collection names where possible, and world unit interpretation is carried through. NURBS surfaces are tessellated to mesh, so analytical curves are not preserved, and constructs like BlockInstances become baked geometry. On export, the scene is written to OBJ, converted to .3dm, and saved to disk, with object hierarchy mapped to Rhino layers and scale and unit metadata included.

Packaged as a focused extension under GPL licensing, it is tested on Blender 4.2 through 5.1 and can be installed alongside other Super3D format add-ons without conflicts.

Who is Super3D Import & Export .3Dm best for?

Super3D Import & Export .3Dm is best for product and industrial designers, jewelry and footwear studios, and arch-viz teams who need to move Rhino .3dm models into Blender for rendering, lookdev or motion without keeping a Rhino seat per artist.

How much does Super3D Import & Export .3Dm cost?

Super3D Import & Export .3Dm is completely free to download and use.

Key features

  • Dedicated Blender File menu entries for importing and exporting Rhino .3dm files
  • Format conversion handled through the Super3D cloud service, so no Rhino license is needed
  • Import tessellates visible polysurfaces and meshes to Blender geometry, preserving layer names as objects or collections and world unit interpretation where possible
  • Export writes polygon mesh geometry into a .3dm container, maps object hierarchy to Rhino layers, and includes scale and unit metadata
  • Opens Rhino 8 files via a backend updated regularly to track the latest .3dm format
  • Installs alongside other Super3D format add-ons without conflicts, each shipping as a separate extension with its own ID
  • Packaged as a GPL-licensed extension tested on Blender 4.2 through 5.1

Frequently asked questions

Does Super3D Import & Export .3Dm preserve NURBS surfaces?

Super3D Import & Export .3Dm does not preserve NURBS surfaces. Because conversion runs through OBJ, NURBS and polysurfaces are tessellated into a polygon mesh, and analytical curves are not carried over. Rhino-only constructs such as BlockInstances and render materials with custom node trees become baked geometry, while annotations, dimensions and hatches are dropped. If you need NURBS-accurate geometry, keep the original .3dm and use this add-on for Blender-side rendering work only.

Does Super3D Import & Export .3Dm need Rhinoceros installed?

Super3D Import & Export .3Dm does not require Rhinoceros to be installed. Conversion runs in the cloud through the Super3D service, so you only need Blender and an internet connection. On import, the add-on uploads your chosen .3dm file to the service, then downloads the result and merges it into your active scene. On export, the scene is written to OBJ, converted to .3dm through the same service, and saved to disk.

Which Blender versions does Super3D Import & Export .3Dm support?

Super3D Import & Export .3Dm is tested on Blender versions 4.2 through 5.1, and its legacy bl_info entry covers Blender 4.0 and later. The add-on is packaged as a focused extension under GPL licensing, adding its import and export entries directly to Blender's File menu. Because it relies on the Super3D cloud service, an internet connection is also required. For the most current version support, check the developer's page before installing.

Can Super3D Import & Export .3Dm open Rhino 8 files?

Super3D Import & Export .3Dm can open Rhino 8 files. The Super3D backend is updated regularly to track the latest Rhino .3dm format, so newer files are supported through the cloud conversion service. Keep in mind that import tessellates visible polysurfaces and meshes to Blender geometry, preserves layer names as object or collection names where possible, and carries world unit interpretation through the conversion service.

Can I install Super3D Import & Export .3Dm alongside other Super3D format add-ons?

Super3D Import & Export .3Dm can be installed alongside other Super3D format add-ons. Each format ships as a separate extension with its own ID and operator names, so there are no conflicts between them. This particular add-on covers the Rhino .3dm format only, adding dedicated import and export menu entries in Blender. It is listed as free here, so check the developer's page for current licensing details.
