Waffle Structural System: Using Grasshopper to Output Structural Ribs to a Laser Cutter or CNC Mill
AOP
24 Comments
Click to see larger imageI have been working on a definition for Rhino's Grasshopper plugin that would create a notched "waffle" structural system for any given surface. With this definition, you can specify the number of struts in the X & Y axis as well as the strut depth and the notch thickness (or the strut material thickness). The waffle system has a few components that define the strut labels and has a slider to control the label size to keep the model organized. Finally, the definition orients the strut curves to the X-Y axis so that the curves can be easily output directly to a CNC mill or laser cutter.
Also, if you are able to use this definition to create a waffle structure of your own (either laser cut or CNC milled), please email me some images and I will post the work on this website. Good luck.

Hi pit... I haven't really looked at that definition in a while. I could potentially try to put something together, although there have been other people who have created their own definitions that work similar to this one and work for GH ver 0.6.0019. If you email me, I can probably send you a link or a file of one of these definitions if you are in a bind.
As a new user of grasshopper, your website has proven an excellent resource. thanks for sharing this file and all the knowledge!

I think it needs some modifications. when I try to "unfold" and place the geometry in place, it shows all. I think Brep + XY plane region intersection could work out in here. am I right? I don't know if it is tool's issue or it is me, who makes it somewhere wrong. thank you for this great tool. I hope I can use it sometime to built my models.

I'd like to thank everyone for their interest in this script. It was originally written for GH version 0.5.0099 which lacks many of the capabilities of the latest WIP versions. For those who are interested in testing out another waffle script definition that will work in GH versions 0.6 and higher, please check out this post. Thanks again. I hope this helps.
