I'm trying to do something similar like the PH file for a university project (this file came from a .stl file, not editable). I don't have much expertise in SolidWork and don't know if I'm in the right way, but started with 2 surfaces to after use knit surface with the option of create a solid and merge the entities, but solidworks gave me an error saying the solid can't be created. Please check my file MO1.
Maybe I should start with a 3D Sketch or other way unknown to me?
Somebody can help me with some intructions to do what I want using surfaces or other elements.
Thank you all¡¡¡
