INSIDER: A Brief Tour of Select Grasshopper Add-Ons

We look at 35 Grasshopper plugins that add additional capabilities and superpowers to the number one AAD tool in the market used in AEC. Importantly, there are quite a few GH plugins working for the Mac version of Rhino + Grasshopper—a growing reality that is good for the market.

Grasshopper Plugins

In this brief article, we briefly discuss 35 Grasshopper plugins and what they essentially provide to the Rhino + Grasshopper user community. They are organized by category and we provide information on which plugins say, or we could confirm, work on both the Windows and Mac versions of Rhino + Grasshopper. Importantly, many entries in the Food4Rhino page can be incorrect in which plugins do or do not work on the Mac versions of Grasshopper. Lastly, we provide links and a direct link to a web page by the developer if one such exists.

Environmental Analysis and Simulation

Ladybug Tools — Ladybug and Honeybee are the most important open-source environmental analysis plugins for GH (Grasshopper) but if you really want to learn a lot about them and where the actual developers are going with these technologies, read our feature INSIDER article. ( See, Architosh, “Ladybug Tools Aim to Take Environmental Analysis to a Wider Audience,” ). Click here for the Food4Rhino page here. (GH Mac / GH Win)

ArchiDynamics — This plugin creates an interface between Grasshopper and ArchiDynamics Standalone software for real-time wind analysis on buildings, structures and urban developments. It requires GH 6 and it also requires the LunchBox plugin installed first. Importantly about the Standalone version. A Mac version of it will be available soon, says the developer.  Food4Rhino page here. (GH Win)

Eddy — A plugin for wind and outdoor comfort analysis and sustainable architecture design. Unlike other CFD tools, Eddy is easy to learn and use and provides architects with actionable ventilation and comfort metrics such as pressure coefficients and the UTCI distribution. The developers are associated with Cornell University’s Environmental Systems Lab (ES Lab).  Food4Rhino page here. (GH Win)

SWIFT — This plugin for doing advanced CFD modeling with OpenFOAM through Grasshopper. If offers Virtual Wind Tunnel and you can map outdoor wind comfort maps, obtain facade pressure coefficients for multiple wind angles and much more. Beta status but a cool plugin. Food4Rhino page here. (GH Win)

Architecture and BIM

SkinDesigner (SGaray) — This is a really cool plugin for the rapid generation of facade geometries from building massing surfaces. We learned about this plugin from Architosh’s feature on AIA Firm of the Year, Boston’s Payette, in our feature on that firm here. (see, Architosh, “Bespoke Computational Tools at Payette Drive Unforeseen Values to Firm and Client Alike,” 5 Feb 2018.)  Santiago Garay doesn’t have a specific website for this plugin but support is managed via email and the Food4Rhino page here. Interestingly, even though it was not tested on Mac, a user got it running. (GH Mac / GH Win)

Garay’s own SkinDesigner is shown in this image in use with Human UI, also another GH plugin.

Karamba 3D — is an interactive, parametric structural engineering tool using the finite element method that allows the user to analyze and respond to three-dimensional beam and shell structures under loads. It works with the Galapagos solver. It is associated and developed in cooperation with Bollinger und Grohmann ZT, GmbH, Vienna, Austria, and folks are doing remarkable work with it that you can see at the official Karamba 3D website here. Food4Rhino page. (GH Win)

Salamander 3 — this plugin is for structural analysis and enables the user to draw beams, slabs, etc in Rhino alongside the architectural geometry. You can specify loads inside Rhino + GH. You can export to Autodesk Robot and Oasys GSA or even ETABS models. The tool is associated with Ramboll. A cool thing discovered at the Ramboll Computational Design blog site is they have a “complete” Beginner’s Guide to Visual Scripting with Grasshopper. This was written in 2017 and includes extensive text and visuals plus a video. (tutorial is Rhino 6). Food4Rhino page. (GH Win)

TT Toolbox — this GH plugin is developed by Thorton Tomasetti’s CORE studio, the globally well-known engineering firm’s computational research group. CORE develops lots of custom software for the firm and their projects but within this range of activities, they have developed several Grasshopper tools like this one. Food4Rhino page. (GH Win)

Platypus — this GH plugin also developed by Thorton Tomasetti’s CORE studio, was created to allow Grasshopper users to stream geometry to the web in real-time. It works like a chat room for parametric geometry and allows for on-the-fly 3D model mashups in web browsers. Food4Rhino page. (GH Win)

BIM GEOMGYM IFC — this plugin by GeometryGym is an Open BIM add-on for Rhino and Grasshopper enabling IFC (Industry Foundation Classes) model generation and exchange for Open BIM tools like ARCHICAD, Revit, Bentley’s OpenBuildings Designer, Tekla and other BIM software with IFC functionalities. This useful plugin’s latest update was for ggRhinoIFC for Mac back in December 2019 and the tool works on both Mac and Windows versions of Rhino 5 as well as version 6 with some limitations, it appears. Food4Rhino page here. (GH Mac / GH Win).

BullAnt — a plugin by GeometryGym like the one above, this GH plugin features computational design tools to enhance and extend the parent program. BullAnt features commands including mesh relaxation (minimal surfaces), mesh inflation (ETFE cushions), symmetry automation, tessellation (polygon packing), structural modeling/sketching (including parametric generation in Grasshopper), geodesic domes and curve network processing. Food4Rhino page. (GH Mac / GH Win).

BullAnt is a GH plugin that enables structural analysis and investigation capabilities to the GH environment. It features a library of common structural shapes.

Topologic — this GH plugin is a modeling library that enables hierarchical and topological representations of architectural spaces, buildings, and artifacts through non-manifold topology (NMT). This type of modeling representation was originally created by Dr. Robert Aish and presented in 2013 at AAG. Dr. Wassim Jabi teamed with Dr. Aish in 2016 to create and advanced this technology into a platform ideal for integration with tools like Dynamo and Grasshopper. Topologic is well suited for creating lightweight representations of building with subdivision, zero-thickness and internal surfaces where the user can query cellular spaces. Food4Rhino page. (GH Win)

PCPA_GH — this plugin is a collection of modeling tools to expand the functionality of Rhino + Grasshopper by the REACH group at Pelli Clarke Pelli Architects. This GH plugin is specifically crafted for “design-oriented” practices it is in constant beta form and available with no warranty of performance. While the famed architecture firm’s plugin is available for use, the license expires every two weeks and one must renew it through a form. A website link on the GH plugin goes here. Food4Rhino page here. (GH Win) 

ParaBrick —  a useful GH definition rather than a plugin for designing parametric brick walls. Food4Rhino page here. (GH Mac / GH Win)

Reader Comments

  1. Author of Pancake. Pancake is initally aimed for better data exchange (between Rhino5/6, direct GH file I/O for multiple formats, etc…) 🤔 Somewhere during the progress I found some tweaks are quite useful and added them, e.g. do an emergency save when GH lost responsiveness & hint param access. The plugin itself is both for advanced and everyday users (for the tweaks). I should definitely write a better description, though.

  2. Dear Pancake author, thanks for the comments. Yes! I agree a better description would be most useful for GH novices and those trying to understand the world of GH plugins. Your input is valuable so thanks again for writing in.
