Close the surfaces or the brep and unroll them

Hi ! I have a problem for closing my curves to make a surface with my hot air ballon model. Can anyone help me ? I have also a problem to unroll the strip of the skeleton that will maintain the model. They straddle each others.

Please.

Best,

Nastia

BTW: I have other far more sophisticated ways (including assembly "notes") to unroll things but they are carried over solely via code (C#) and that's the reason that I haven't use them here. If however in the future you want something tricky and/or "realistic" (like wasting the min material when fabricating the parts (i.e. the so called packing)) drop an e-mail.

That said the "real-time" packing part of the equation is more than critical during ANY design (in real-life, not in this Academic case).

Yikes + Yikes (+ Yikes).

Either blame Rhino for this last vector orientation oddity or Karma or something.

Prior checking the DotProduct (last VS the previous)

After

On the safe side: added a DotProduct check for the fist VS the next vector as well

Accept my apologies for not spotting this (lack of espresso without doubt).

If you want to nest your profiles, you could do that :

convert the curves to SVG with Nik "Rhino Standard Vector Graphics (SVG) File Exporter For Browsers"

http://www.grasshopper3d.com/forum/topics/rhino-standard-vector-gra...

Don't forget to add a rectangle as packing area.

As my computer doesn't allow to write on c:\ I replace in Python component C:\ directory by c:\SVG :

text_file = open("C:\Output.svg", "w")

text_file = open("C:\SVG\Output.svg", "w")

Go to http://svgnest.com upload your SVG and select the rectangle, go to configuration and add some Space between parts, I put more than the double tolerance of the curve precision.

click "start nest" ... wait I will have something like that. Not very useful with a single shape, but it works.
