algorithmic modeling for Rhino

Uses the Rhino Unroll command in order to unroll surfaces or polysurfaces - result is not always what you need :)

Thanks, I'll try It now!

thats nice, can you provide some examples?

thanks!

Thank you so much for this. My geometry uses lots of bent plywood sheets and I needed a way to unbend/unroll multiple breps and lay out for cnc machining and laser cutting. Hugely helpful.

Glad it was useful! 

Wow! thanks... This is working incredibly. I can even unroll a number of breps at the same time... But is there a way to make them unroll in a specific place? say  right next to the surface they belong to?

I organized on a grid each of a series of parts that make up a sort of blob, and its way important that i correctly attribute the respective I.D. tag.

thanks in advance.

I did it!!! and i am terribly happy. Since I had arranged the parts (not unfolded) in a grid with corresponding text, I plugged the new unfolder BEFORE organizing (orienting) the parts and it honors the same order.

could you tell me a little about how you put together the unfold command?

Hello Danniely,

It is just calling the Unroll Command from Rhino. Therefore the unroll behaves similarly as the rhino unroll.

Anyone know how to control the placement of the final unrolled surface?

Ie. The input surface location and direction changes when you unroll the surface. It is reoriented.

You may want to also check out FabTools.  It could give you a bit more layout control.
