Extract a Surface from a Solidworks 3D Part

Hello

I want to extract surfaces from a prototype airplane (Carman wing) for example and build the mold to make it. I proceeded with offset surface with thickening to 0mm, but from there, it was no longer possible to find the function(s) allowing me to extract it and deposit it in a new drawing to make my mold.

Thank you in advance for your help.

Hello

Which version of Solidworks are you on??? Because you can use the function remove the face or delete/keep the body to keep the part you want  but first make a configuration to keep the complete part in the defect and in the other the part to be molded; Then after that, you create 2 canister parts for the mold and you use the borrowed function but you have to be in an assembly to use it.

What is the purpose of wanting to create a surface from volume?

To make a mold, you don't need a special surface.
