What’s new in Rhino 6 (for Mac & Windows)

In Rhino 6, we’ve fully embraced Grasshopper – the wildly popular visual programming language – by “baking it in.” Grasshopper is no longer beta; it’s a stable development environment. We’ve also rewritten some features and renovated workflows that needed fundamental overhauls to make them truly productive.

These are the highlights…


rhino grasshopper

The long beta period is over: Grasshopper, the world’s most beautiful programming language, is now a full-fledged part of Rhino. Used in some of the most ambitious design projects of the past decade, Grasshopper, like Rhino, has become a robust development platform. Grasshopper provides the solid foundation for many incredible third-party components ranging from environmental analysis to robotic control.


rhgino presentation

Presentation is key: during nearly every phase of design, you need to communicate, getting “buy-in” from clients, customers, collaborators, or the public at large. We’ve improved Rhino with the aim of helping you present your work: be it “quick and dirty” or “high-res glossy.” With major changes to Rendering, Materials, or just plain capturing the viewport, it’s now easier and faster to present, discuss, make decisions, and iterate.


rhino display

Rhino’s new display pipeline is faster, more stable, and uses features found on modern graphics hardware, like GPU sensitive shaders and memory optimizations. This results in fewer GPU-specific display glitches and more consistent, beautiful, and frequent frames, even with large models. In some conditions, display speed can be up to 300% faster.


rhino documentation

Modeling is just one part of the design process; you also need to show how to build what is on the screen. We’ve refined many parts of the documentation workflow, from a completely reworked annotation-style interface, to better DWG support, and RichText throughout. It’s now easier to convey accurately and clearly the what and the how of your design.

Licensing & Administration

rhino licensing and admin

We have worked hard to make Rhino easier to install, license, and configure. There’s a great new option to license Rhino using the Cloud Zoo. Please check out the new System Requirements as well.


rhino make 2d

Make2D has been completely rewritten to provide faster, better, cleaner, more customizable results.

Rhino Refinements

rhino refinements

Small quirks add up to painful paper cuts over the course of a prolonged modeling session. In Rhino 6, we’ve fixed hundreds of minor bugs and consolidated disparate – but similar – features into single commands, making Rhino much more refined.

Development Platform

rhino development platform

Rhino is more than just a modeler. With a rich ecosystem of plugins and an open set of development tools, Rhino is quickly becoming the development platform for those seeking to push the envelope of design. Rhino 6 brings major improvements to our free SDKs, with API refinements, better documentation, and more access to Rhino commands from Grasshopper.


rhino serengeti

We’re constantly improving Rhino. Rhino 6 users have access to the Serengeti community and our Work-In-Progress (WIP) builds. The WIP builds are where we are developing future features like SubD support, Grasshopper 2, a new real-time rendering engine, and much more.

Every type of physical product design relies on technical illustration and 2‑D drawing to concisely communicate ideas, specifications, and instructions to people in design, development, and fabrication. Our goal for Rhino 5 is to make it easier to create 2‑D drawings and illustrations for every discipline in every notation system and visual style used around the world.

Annotation objects include: arrows, dots, dimensions (horizontal, vertical, aligned, rotated, radial, diameter, angle), text blocks, leaders, hidden line removal, Unicode (double-byte) support for text, dimensions, and notes. Dimensions in perspective views are supported.

Digital Fabrication and 3‑D 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 3‑D 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 3‑D topography of a large city.

3‑D Capture

Capturing existing 3‑D data is often one of the first steps in a design project. Rhino has always directly supported both 3‑D digitizing hardware and 3‑D scanned point cloud data. Rhino V5 has enhanced support for:

  • Large point clouds. 3‑D 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 3‑D 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.


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).

Large Projects

File management tools for managing large projects and teams include: Notes, templates, merge files, export selected objects, save small, incremental save, bitmap file preview, Rhino file preview, export with origin point, worksessions (Windows only), blocks, file compression for meshes and preview image, send file via email.


Rhino is compatible with hundreds of different CAD, CAM, CAE, rendering, and animation products. The openNURBS libraries allow hundreds of other applications to read and write Rhino’s native 3DM files.

Developer Tools

  • The world’s most robust 3D development platform for specialty modeling, rendering, analysis, and fabrication tools across a wide variety of disciplines.
  • More accessible development tools: RhinoCommon (.NET), Grasshopper, Rhino.Python, RhinoScript, the Zoo license manager for plug‑ins, and the Rhino Installer Engine are key ingredients.
  • Comprehensive documentation
  • An active developer community
  • Open source more of the Rhino development tools, including Rhino.Python, RhinoCommon, and the 3DM viewer on iOS.
  • Free‑of‑charge developer tools, including technical support, marketing support, and training. All of our development tools are available to everyone with a valid Rhino license. No special program registration, contracts, license agreement, or approval is needed.
  • Localization and translation services are available. Details…

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.


The major goal for each new Rhino release is to make it easier for managers and system administrators:

  • Ease to share (float) licenses in a workgroup and company using The Zoo or Cloud Zoo license manager.
  • Tools for easy license deployment in larger installations
  • Take more advantage of current hardware
  • Automatic notification and download of current bug fix service releases
  • Provide more training and support options

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.
