Hi, im new with Rhino and i have just one wish.
I would suggest using ReduceMesh if your model is already a mesh or use Mesh to convert a surface or solid model to a mesh first… then use ReduceMesh to simplify it.
Ok, do you know how to fill it inside, thanks!
Can you post a model with what you have now? I’m not sure what you mean… meshes are like a skin. If it is a closed skin with no gaps it is considered a closed polygonal mesh. You might be asking about something else though…
