After this tutorial, we are still working on the basic ways of making contouring easier in Grasshopper. This is the updated version of the 2-year old contouring definition in Grasshopper, with some additional functionality. It produces a flat and properly numbered output of each section. However it does not include optimized nesting to reduce material use. Here is the Grasshopper definition (don’t left click, use right click and “save” option) [GHX: 0.9.0076] and the Rhino test file [3DM: Rhino 5].

This video is dedicated to the Design Computing and Basic Design students, who “contour” and then move each and every section by hand, one by one, in order to fabricate their laser-cut homeworks from cardboard. It could also be a macro but I prefer this because it somehow does not work in all conditions. Maybe you should orient your contouring results similar to shown in the video, and then use shear command to spread them.

This is a macro exercise in Rhino, showing that Rhino is pretty much capable of automating some cool text effects. Just copy and paste below code into the command bar of the Rhino, or open macro editor by typing macroedit, then paste there and press play. You’ll enter any string when prompted, then the macro handles rest of the process. You can play with the parameters by changing numeric values you see in the macro. ! _show _selall _delete _-text 0,0,0 h 10 _pause _sellast _setobjectname tex _boundingbox o c […]
