algorithmic modeling for Rhino
Demonstration of our new Unfold Brep component for Grasshopper, available in version 1.5 of TT Toolbox for Grasshopper.
Taz, Pepakura still rocks - I have some students using it (for mesh unfolding) at Pratt, and the tabs are a great feature.
Dimitrios, great suggestion. One feature that we might expose in our next release is the ability to explode all of the unrolled faces (instead of letting the unroller class determine which edges stay joined and which are cut) - this feature is already built in to the unroller class. We'll certainly need to tackle edge and face numbering if we do so ... and as far as I know, the unroller class does not do that out of the box. We'll have a look!
Not to shill for other software, but Pepakura is also a great tool for unfolding complicated solids. If I remember correctly it may also automatically create tabs at the seems. It's been a while since I've used it.
Hi Ben, this is a great component - I'm sure our users on www.curvedfolding.com would love it! Any chance you can post it there? Greg, RoboFold.
Very useful for folding model making.
Just a though in case it s an easy update: To number the original faces and the unrolled ones, so model-makers that cut the peaces know how to assemble them back. (when they are cut into individual components let s say from a laser cutter?)
Thank you Pieter -
The component will only attempt to unroll Breps. No meshes - including stanford bunnies - allowed.
About the seams - to be honest, we aren't sure how the splitting edges are chosen. Our component is essentially a wrapper around the Unroller class in Rhinocommon, and there doesn't seem to be a way to specify which seams split and which stay joined.
Beautiful! Just a few days ago I spent a gra$$load of time trying to get to how to reorient these planes.
That's really very very cool Ben. I'm wondering if it can unfold the stanford bunny, for instance. What determins where the seams are going to go?
