Rendered Display mode captures more lighting in a realtime working mode.
Viewports and Rhino Render now use the same rendering settings.
Transparent color support on layers and objects.
Per face color support for polysurfaces and SubD.
Rendering and Presentation
High-quality presentations are critical to most design projects.
Features include: Rhino Render, a raytrace render with textures, bumps, highlights, transparency, spotlights with hotspot, angle and direction control, point lights, directional lights, rectangular lights, linear lights, and shadows, and customizable resolution, realtime render preview, realtime render preview selected objects, turntable, export to many common file formats used by renderers, rendering plugin support, settings saved in file.

Plugin extendable Post-effects, tone mapping, and final image filters.
Physically Based Rendering (PBR) Materials: PBR (Physically Based Rendering) materials are the best choice for renderings and presentations for rendering professionals who want realistic-looking materials. They are fast becoming the standard for material libraries, content authoring, scanning applications, and are supported in many modern applications. PBR materials are supported natively in Rhino’s rendering engines and viewports.
Every type of physical product design relies on technical illustration and 2D drawing to concisely communicate ideas, specifications, and instructions to people in design, development, and fabrication. Our goal for Rhino was to make it easier to create 2D 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.
In Rhino 7, we’ve added…
Layout Management: The vertical panel makes it easier to work on a model with layouts by adding a vertical panel for layout management.
Enhanced Text Fields: Text fields are special expressions within the text object that can dynamically update when a change to the linked property or attribute is detected.
Gradient and Transparent Hatches: Gradient and Transparent Hatches make your illustrations, diagrams, schematics and any 2D representation more beautiful.
Display Color Transparency on objects and by layer.
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.
In Rhino 7, we’ve added…
Single-Line Fonts: Single-Line Fonts help improve the speed and quality of your CNC engravings.
Mold Making tools: For mold makers and tool designers, Rhino’s mold making tools assist in the model-test-revise workflow.
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.
QuadRemesh: Quickly create a quad mesh from existing surfaces, solids, meshes, or SubDs—ideal for rendering, animation, CFD, FEA, and reverse-engineering.
Improved mesh intersection results.
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.
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 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 have 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 for Windows has robust support for plugins, such as RhinoTerrain™, that provide specialty tools for these new Rhino users.
3D digitizing support: MicroScribe®, FaroArm®, and ROMER – Windows only.
Inspection and Analysis
Design realization requires high‑quality 3D models in every phase of design, presentation, analysis, and fabrication. Rhino includes tools 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).
New in Rhino 7:
EdgeContinuity now uses line hairs to visualize distance, tangency, and curvature between an edge pair.
PointDeviation: Added Maximum distance and minimum distance statistics.
Clash Detection: a new Grasshopper component.
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.
In Rhino 7, we’ve improved fidelity for existing formats and support for SubD where possible. In addition, you can now…
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 7:
Grasshopper Player: Turn your Grasshopper definitions into Rhino commands.
Clash Detection: Quickly search a large number of objects to find points of intersection between pairs of clashing objects.
Component placeholders: Placeholder component for missing plugins.

Beyond Rhino 7
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 invite current users to try, test, and provide feedback on the next release while it is still in development.
Since many development efforts span more than one release, we have set up the Serengeti Project to give users a 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 improved SubD support, Grasshopper 2, rendering and display improvements, and much more.
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
Please post your Rhino 8 wishlist items as topics in the Serengeti category on Discourse.
Rhino 8 Development
Rhino 8 pre-release builds are available to Rhino 7 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 7 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 8 to production.
- All Rhino 7 users will be invited to participate in the Rhino 8 development process. There is no charge.
- Each phase typically takes more than six months.
- Each WIP and Beta build 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.
