algorithmic modeling for Rhino



The CORE studio at Thornton Tomasetti uses Grasshopper everyday to enhance workflows amongst many engineering disciplines. We draw a lot of help and inspiration from this community and hope that you will find some of the tools that we have created helpful, too.

TT Toolbox

Head over to food4rhino to download the second edition of the TT Toolbox plugin for Grasshopper.

TT Toolbox features a range of different tools that we from the CORE studio at Thornton Tomasetti use on a regular basis, and we thought some of you might appreciate these.

You can find a primer with a complete listing and documentation of our tools inside of the downloadable zip file.

Some of the tools included in TT Toolbox are:

  • A lightning fast Excel Reader/ Writer with many options such as file creation, work sheet creation, conditional formatting that matches GH coloring and more.
  • A Section Sweeper (inspired by Jon Mirtschin's StructDrawRhino plugin) that sweeps BREP of structural shape sections around guide curves.
  • A Safe-Delete component that lets you safely delete user-selected Rhino geometry that is not currently referenced in Grasshopper.
  • A CAD exporter that [batch-] creates dwg files from GH.
  • A reader and writer for Google spreadsheets

Other tools include:

  • Unit converter
  • Match Tree Structure
  • Retrieve Tree Branch
  • Retrieve Tree Item
  • Curve Type
  • Get Geometry Names from Rhino
  • Remove Duplicate Lines based on a tolerance value
  • Sort Curves by Direction

To install:

  • In Grasshopper, choose File > Special Folders > Components folder. Save the gha file there.
  • Right-click the file > Properties > make sure there is no "blocked" text
  • Restart Rhino and Grasshopper

Though we did some alpha testing in the office, we may not have covered all of the bugs and will certainly appreciate your feedback.

Best Regards,

The ACM Team

The next version of TTToolbox will feature an interface to get World Cup statistics. Here are a few that we generated with Grasshopper:

The Brute Force solver component allows you to run all possible combinations of a selected set of sliders.  This is an alternative method to using Galapagos or other optimization engine when the design space is either limited or it is valuable to see all possible options.

New Platypus version available today on food4rhino!  We added GH/browser slider sync, and GH>GH streaming geometry in this release.  Just in time for Matt's hack at our #AEChackathon this weekend.  Enjoy!!

Live GH Update from Excel!

TT Toolbox 1.2 contains a new version of our 'Read From Excel' component that allows for live [Grasshopper] updates from Excel.  Once you read data from an Excel worksheet, our component listens for any changes on that sheet.  When it hears an update, it automatically updates itself and any downstream components.  Give it a shot and let us know what you think!
