Unroll brep from 3d to 2d

Good morning guys,

Where can I find the Unroll Brep component in GH ?

I couldn't find it anywhere .. Shall I add some plug ins ?

Thanks ..

SEG has an unroll component (but I never tested/use it).

The unroll is performed using C# like this:

Anyway have fun with the def attached (C# code only) that decomposes a Brep (with planar BrepFaces) into a linear layout schema and optionally performs an unroll (the art of pointless).

best, Peter

BTW: Unroller class (Rhino SDK):

Thank you peter,

this is working great, but in a different origin than the original Brep, the unrolled brep is found at (0,0), I would like to have it at the same base of the original Brep ..

check the attached image ..

Cheers

Er ... great? (you mean awfully bad, I guess, he he).

Allow me to make some "adjustments" on that code

Thanks a lot peter

I mean if you need only the Unroller thingy ... you don't need the rest of the code.

more soon

Exactly, all what I need is to unroll the brep (strip by strip) keeping same strip origin ..

Cheers peter

Wait a minute:

Doing this via a quite short C# (without the "layout" calculations) is not nuclear science ... but ... well ... you'll get overlapping arrays (unroll outputs an array) or lists of brepfaces.

I suspect that this is another "very-simple" case ...

more soon

Update: spend 12.45 minutes on that one (just another "simple case" , he he)

Here's what The Dark Side (C# only, not SEG, KGB, BBC, ABC or whatever) has to say for Ibrahim:

Allow me a couple of minutes more (for adding some bugs more in the code: always In The Name of Science, what else?) and I'll post the salvation ASAP.
