Mesh Difference Problem

I am having an issue when I try to 'mesh difference' the meshes shown below.

I want the resulting mesh is a mesh top. However , the result "Mesh Difference" is the mesh down, as shown in the image below. Does anyone know how to reverse the resutado ?

Hello Juliana,

I don't think you will get an answer without uploading your files...

cheers,

It looks like you're trying to split the mesh with a plane. There's a component for this that will give you the results both above and below the splitting plane, and it should run lighter than mesh difference does.

I tried this ppção with mesh division , however it does not generate any results.

There is no geometry internalised in your gh file.

Please read this post and upload your file(s) again.

Thanks,

nikos

ps. did you check David's suggestion above?

Isn't this the same question as in the other post?

No, this is another file where I have problem with Mesh Difference, I put the batteries in the origin 0,0,0 and still don't worked!

No, the batteries have nothing to do with this, my suggestion was to move the Rhino geometry (lines, points, etc) to 0,0,0.

Still, if you want to get the top or bottom part of your mesh, the right way is what you did in the other post, using [MSplit], not [MDif].

btw, here is a simple solution so that you don't have to change wires every time you reset kangaroo. Double click the boolean toggle to set it to false and then change it again after kangaroo has started.
