Have you ever wondered how buildings with complex architectural designs are modeled in Tekla Structures? It’s achieved by algorithmic modeling for Tekla Structures using Rhino/Grasshopper. The Grasshopper - Tekla live link is a set of Grasshopper components that can create and interact with objects live in Tekla Structures. To make it work, it requires Rhino with Grasshopper installed. 

Check out this double-curved roof being modeled in Tekla Structures with the live link to Grasshopper.

How to get it working

A free Tekla Structures extension called Grasshopper-Tekla Live Link CAMPUS edition was recently released for our Tekla Campus Edu users. Please note that this version of the Tekla-Grasshopper live link will work only with the Educational configuration of Tekla Structures. It can be downloaded here.

It requires Rhino (download) and Tekla Structures installed. 

  • Grasshopper is included in the Rhino 6 install. When using Rhino 5, Grasshopper needs to be installed separately (download).
  • You can try out the full version of Rhino free for 90 days. The Grasshopper add-on is free of charge.

How to check if the Grasshopper-Tekla Link has been installed successfully

1. Be sure the Tekla plugin is loaded by going to Help > About in Grasshopper:

2. Check Rhino's Command history (type "CommandHistory" into the command line) immediately after you've launched Grasshopper. Check for any error messages. 

3. Do a search for the file "GrasshopperTeklaLink.gha" and  "GrasshopperTeklaLinkEducational.gha" in C:\Users\[username]\AppData\Roaming\Grasshopper\ and make sure there's only one copy.

4. Type "GrasshopperDeveloperSettings" into Rhino's command line and check whether COFF loading has a checkmark. If not, check it and restart Rhino/GH. If it already is checked, you could also try to uncheck it, check again, and restart.
