Turning a mesh into a solid, or NURB

Hi!

I'm having problems when trying to turn a mesh into a solid, or whatever object that I can then trim and make a 2D drawing of it.

The thing is that I modelled a skin with grasshopper, and this skin consists of meshes. When trying to turn them to solids, Rhino doesn't let me, and the prompt "The meshes with more than 20,000 faces are too big for MeshToNurb" pops up. I need to do this to make 2d drawings of my model, trimming in section and in plan views, and then use them in Autocad. Anyone can think of any other way of trimming this objects?

I hope I have explained myself correctly...

Thank you very much,

Miguel

It'd be useful to attach your geometry, or at least an image. Making a polysurface from such a large mesh is a hugely heavy process (which is what mesh-to-nurbs does), and you'd have a hard time working with it for making 2D drawings anyway.

There are a few tricks you can use to get decent 2D drawings from meshes, but it becomes difficult to layer these in with other objects, particularly when it comes to correctly ordering objects. Again, here images and clearer description of what drawings you want to achieve would be helpful.

Hi David. Thanks for your reply. In the file you can see an example of one of the meshes I would like to trim to make 2D drawings. I know it is a heavy process and maybe the best solution is to divide these meshes into smaller ones.. I've got.....litke 40 meshes like this one. The planes are illustrative, but they could be the ones I would like to use to trim the mesh.

Thanks again!

Well, I forgot to mention that if I am trying to turn meshes into polysurfaces, it's due to the fact that when I try to use the command of "create2ddrawing" it doesn't detect anything that is a mesh...
