HELP! "Offset surface" splits the surface and offsets them in different directions :(

Hey,

I have a little problem. I want to offset the surface you can see in the picture on the right site. The surface on the left site is the result I got by Grasshopper. The Grasshopper code worked on easy samples without problems but on this multiple surface it didnt worked. Someone knows why? PLz help :)

Hey,

here are the files. I want a constant wall thickness so it should offset the surface upwards.

I hope you can help me.

FYI weaverBird has a mesh thicken which may also work for you.

I was going to suggest that as well but I just realized those cuts you see are all individual surfaces, its not a mesh, and each one of those surfaces contains yet more tiny surfaces. I made it a mesh and did mesh thicken and got similar different direction results. I'm thinking the surface normals are messed up, Test123 why is it necessary this surface be so broken.

Hey,

it seems to work with weaverbird I joined the surface then created a mesh and used the thicken tool by weaverbird. not the perfekt result but maybe its enough at first I will try to process with it.

It is a multiple surface because I used a complicated model before which consists of many surfaces. Till now I get no single surface model so I have to try it with such a multiple surface. Have a look at the picture it looks not bad for just trying 5 min. Maybe there are options to get a better result in weaverbird.
