Parametric “Snowflake” Fabrication Project Using Rhino’s Grasshopper
Saturday, January 3, 2009 13:58This is a little project I did partly to test out the fabrication capabilities and partly to create “ornament” for the tree at SHoP’s holiday party. I thought I would share the images with you guys to illustrate some of the possibilities of grasshopper.

Nice work Zach! It reminds me of a project a professor of mine was doing a couple of years ago with folding techniques. Yours turned out much cleaner. Nice job.

Awesome. Any chance you’ll be posting a grasshopper tutorial on for this project?

If there is enough interest in a tutorial on this project I could create one. Suffice it to say it will be a fairly long tutorial, so I may try and condense some parts, and focus more on the unique aspects of the project.

This looks great ! Will there be a parametric snow man in the future?

Already in the works.

Very Cool
I add my vote for a tut as well.

Very neat. I have to get some free time to play with Grasshopper more.

yes it is lovely, but i feel i have to point out that we have been doing exactly this for years just with rhino. you can see my wooden lightshades on http://www.davidtrubridge.com, such as ‘kina’ which also uses the same crosses. however i would love to try it with grasshopper too because i guess it gives you the opportunity to adjust things more?

These are beautiful projects David. I would love to see the process you used to create these in rhino to compare it to the grasshopper version. I imagine it would be fairly cumbersome to make a change. If you have to make a change does it necessitate a rebuild of the entire model? The main advantage I see is that you can change the input geometry to really any shape and still have it flatten the geometry out for laser cutting and at the same time I can apply this definition to all sorts of shapes without anymore effort which frees you up to make a lot more overall shapes. I would love to further this conversation with you and perhaps look at some other designs and how grasshopper can be used.

i used a combination of ‘unroll developable surface’ and ‘create/apply uv curves’. yes it is quite restricted and you have to go thru the entire process again to make a change, so grasshopper is definitely better. but maybe it is good to use a combination of a quick sketch in rhino with this process to see where you are going then to build the grasshopper set of parameters?

hey, i want to see a tutorial too. can you post the link here if its finished?
david, is your rhino sphere perfectly round or have you modeled the material thickness and the overlapping at the junctures too?

any chance of a tutorial, zach….
thanx for the wealth of tuts already existing on this site
cheers

Hi,
I’d love to see a tutorial for the project. It looks really nice.. I can see a lot of potential to create nice object/ building using with similar approach. Thanks.
