Hi @sambrari95
You’ll need to give people a LOT more to go by than just:
What type of shell? For what? Is that your Rhino file (and if yes, please post it instead of just screen grabs)? Is it the organic blop the shell in question? Why is that shell shown not good enough? Are we talking adding thickness to the existing shell ('caused that’s not shelling)? Where are you stuck, what’s the actual problem?
And also post the file along with your question(s), since it’s really hard to help from just a screen grab.
For more details on how to properly ask for help, see this. It was written for Grasshopper, but most - if not all - of it goes for asking Rhino questions as well.
HTH, Jakob
