hey, a bit of a beginner here,

i want to be able to select a part of this mesh below , in order to flatten those parts for physical penalization.

I have tried numbering each individual face, to see if maybe i could select that part from a list, but the list seems quite messy, and I’m not quite sure i’m doing the right thing. see attached:

I would really appreciate the help with 1. selecting a mesh part, and 2. advice on how to proceed on flattening these faces for panelization.

I am attaching my grasshopper file,  
Thanks!

Hi!  
Welcome to this forum!

You didn’t **internalize** your starting curves, so your .gh definition is not building any geometry.  
Also, for who, like me, don’t have your plugins (ex: “MeshEdit components”), can you internalize also directly the mesh itself?

See here, please:
