How to get a solid from a mesh mold

Rhino

Hi,
I will appreciate any help.
I have a shell for a device a mesh one but I want to create a new style. I don’t have the solid shell is a mesh so maybe this is stupid question but there is no way to use the mesh shell as a mold and like in real like creat the mold of the product or device? Since I have the outside (problem is a mesh stl) imagine like if is real life with a silicon mold and we throw a batter inside let it dry and there you go have the product that you can use to boleean difference in any new shape you have and you know is perfect.

Thanks so much I hope you understand what I mean. And hope I can convert that mesh into a solid normal poly surface 3dm

What you are describing is reverse engineering, since you are starting with a mesh.

Note that I’m not saying you cannot do this with out of the box Rhino; however, the process would be more difficult and take longer than using a dedicated reverse engineering tool.

I suggest you hire someone to do the work for this project. If you see more of these projects coming in the future you may want to look at Mesh2Surface, a reverse engineering plugin for Rhino, or or an industry standard such as DesignX.

it could work, but it depends what kind of model you have, since you did not even post a screen shot of it its all guessing games here. ideally you post an image and the model (stl) itself.

one tool which you also have in v7 already is QuadRemesh (if needed with the option SubD) with this you could potentially get a smoother looking model pretty fast. from this point you can remodel the geometry relatively easy or turn into a nurb surface with ToNURBS if that helps your process.
