New in Rhino 6
The Rhino 6 development process started with the overriding goal to remove as many of your workflow bottlenecks as possible, in addition to making thousands of large and small improvements. That meant making Rhino faster and able to handle much larger models and project teams.

Thanks to thousands of pre‑release users, we were able to field test and refine Rhino 6, making it the fastest and most stable version ever.

Digital Fabrication and 3D Printing

As you may know, the Rhino development project started nearly 20 years ago to provide marine designers with tools for building computer models that could be used to drive the digitally controlled fabrication equipment used in shipyards.

We continue to focus on the fact that designs are only useful once they are built and in the hands of consumers. With the cost of digital fabrication and 3D printing technology dropping quickly, more and more designers now have direct access to 3D digital fabrication equipment.

While we are not experts on all the many fabrication, manufacturing, or construction processes, we do focus on making sure that Rhino models can be accurate enough for and accessible to all the processes involved in a design becoming a reality.

Mesh Tools

Robust mesh import, export, creation, and editing tools are critical to all phases of design, including:

  • Transferring captured 3D data from digitizing and scanning into Rhino as mesh models.
  • Exchanging mesh data with many applications such as SketchUp and Modo.
  • Exporting meshes for analysis and rendering.
  • Exporting meshes for prototyping and fabrication.
  • Converting NURBS to meshes for display and rendering.

Both new and enhanced mesh tools, plus support for double-precision meshes, accurately represent and display ground forms such as the 3D topography of a large city.

New in Rhino 6...

3D Capture

Capturing existing 3D data is often one of the first steps in a design project. Rhino has always directly supported both 3D digitizing hardware and 3D scanned point cloud data. Rhino 6 now supports:

  • Large point clouds. 3D scanners have become faster and cheaper, making huge scan files more common. Rhino's 64-bit support and enhanced support for graphic co‑processors has made it possible to work with these large point clouds.
  • LIDAR captures 3D terrain data for agriculture, archaeology, conservation, geology, land use planning, surveying, transportation, plus wind farm, solar farm, and cell tower deployment optimization. Rhino 6 for Windows has robust support for plug-ins, such as RhinoTerrain, that provide specialty tools for these new Rhino users.

3D digitizing support: MicroScribe, FaroArm, and Romer/Cimcore.

New in Rhino 6...


Design realization requires high‑quality 3D models in every phase of design, presentation, analysis, and fabrication. Rhino 6 includes new tools and enhancements to help ensure that the 3D models used throughout your process are the highest possible quality.

Analysis: point, length, distance, angle, radius, bounding box, normal direction, area, area centroid, area moments, volume, volume centroid, volume moments, , hydrostatics, surface curvature, geometric continuity, deviation, nearest point, curvature graph on curves and surfaces, naked edges, working surface analysis viewport modes (draft angle, zebra stripe, environment map with surface color blend, show edges, show naked edges, Gaussian curvature, mean curvature, and minimum or maximum radius of curvature).

File formats supported...

Developer Tools

Plug-ins: The Rhino SDK exposes most of the internal workings of Rhino, making it possible for third-party developers to create powerful plug-ins and add-ons. A programmer's I/O tool kit with source code is available on openNURBS web site.

Scripting: RhinoScript (VBScript) and Rhino.Python support exposes most of the internal workings of Rhino, making it possible to develop powerful scripts.

New in Rhino 6...


Grasshopper is a graphical algorithm editor included with Rhino.

Unlike RhinoScript, Rhino.Python, or other programming languages, Grasshopper requires no knowledge of programming or scripting, but still allows developers and designers to develop form generation algorithms without writing code.

New in Rhino 6...


Features include:

Note: While RhinoScript is still widely used and supported on Windows, we recommend that users and developers move to Rhino.Python for both Windows and Mac. See below.


Rhino.Python is a powerful scripting language in Rhino on both Windows and Mac. Rhino.Python is built for flexibility and clear syntax.

Beyond Rhino 6

Serengeti, named after the largest African Savanna, is where Rhino grows.

We like to involve users in every phase of the Rhino development process. As with prior releases, we will be inviting current users to try, test, and provide feedback on the next release while it is still in development.

But now we have something new. You will be able to participate in the development beyond the upcoming release.

Since many development efforts span more than one release, we have set up the Serengeti Project to give users more direct influence on all future Rhino developments.

That means you can always have access to the weekly Work-In-Progress (WIP) builds of everything we are working on no matter when or if it will be released. Rhino WIP builds are where we develop future features including SubD support, Grasshopper 2, a new advanced rendering engine, and much more.

Serengeti: New in Rhino 6...

Service releases

Rhino automatically downloads service releases to your computer and notifies you when they are ready to install. You can control when updates are downloaded in Rhino Options > Updates and Statistics. You can also download them from here.

For pre-release builds, under Rhino Options > Updates and Statistics select:

  • Weekly to automatically download pre-release builds of Rhino that contain the most recent fixes and enhancements. These builds are tested by the McNeel testing staff for stability and reliability, but may contain bugs that we haven't discovered yet.
  • Service Release Candidates to automatically download pre-release builds that the development team believes are stable, reliable, and are ready for broader testing.

Wishlist management and discussion

There is a Wishlist category on the Rhino forum to help manage the discussions.

Rhino for Mac

Rhino 6 for Mac is in the works. It is an ongoing process and will be released in phases. During the pre-release phase everyone will be invited to give it a try. Details...

Rhino 7 Development

Rhino 7 pre-release builds are available to Rhino 6 users in phases:

  • Work-in-Progress (WIP) builds include prototyped new ideas and technologies. WIP builds (often called Alpha releases) are not production ready, and some ideas and technologies may never be released. Rhino 6 users will be invited to get involved. Your feedback at the WIP stage has the most impact on the design of the features and enhancements.
  • Beta: Once most of the core changes are finished and tested, beta builds are released. The beta builds should be production stable but may not have all the features or user interface finished. 
  • Final: We release a new version only when the beta users tell us it is ready. Beta users are informed when we have stopped development and have released Rhino 7 to production.


  • All Rhino 6 users will be invited to participate in the Rhino 7 development process. There is no charge.
  • Each phase normally takes more than six months.
  • Each WIP and beta builds expires every few months. A newer build is always available before expiration. This ensures that bugs are reported for the latest build, and that we don't receive reports for bugs that are already fixed.
  • The final beta release will not expire for at least two months after the new version starts shipping.
