The Grasshopper script created for the waffle structure in this tutorial can be downloaded here. DXF opened in AutoCAD will have the same value for D/P as it is set above. There is also a separate Grasshopper component called Bowerbird that can be used. The Grasshopper script that has been created so far can be further extended to automate this process as well.
If a physical prototype of a waffle structure needs to be created, some additional steps are required-creating the notches in the ribs at the intersections and then unfolding them to the XY work plane for laser cutting by a CNC machine. Similar to object libraries and CAD and BIM standards, an office can have an entire library of these scripts, ready to be applied to different Rhino models to explore different design forms for its projects. Also, once the script is created, it can be used on multiple projects. We can see that creating a Grasshopper script for a waffle structure takes more time than modeling it directly in Rhino, but it is well worth it-once the script is written, the design is automated and changes can be made instantaneously, allowing many different design options to be explored before finalizing on one. The completed model of the waffle structure in Rhino, including the waffle ribs that were generated from the Grasshopper script. Figure 4 shows just the top surface which has been copied to a separate file.įigure 18.

We will start by first modeling the waffle structure entirely in Rhino, showing how it is less forgiving of design changes as it requires a complete manual re-creation of the ribs of the structure every time a change is made.įigure 3 shows the massing model of a canopy design, the top of which we want to construct as a waffle structure. It assumes some familiarity with Rhino and a basic knowledge of the Grasshopper interface. This tutorial walks you through the steps for modeling a waffle structure in Rhino using a Grasshopper script. While the structure can be entirely modeled in Rhino, the use of Grasshopper-a graphical algorithm editor tightly integrated in Rhino-makes it much more powerful and allows design changes such as the spacing of the ribs and their thickness to be made much more quickly and easily. To create a computer model of a waffle structure, any NURBS-capable application will work, but the application that is most commonly used is Rhino. This is a photo of a 1:3 physical prototype of the structure. To use the Rhino Debugger with your DSS scripts, pass in the bug.
