STL Skin Surface File

[Flite-Metal]

I have an .stl which is hollow. I need to slice it in order to mill it. When Cut3D slices across it what will the resulting G code do when milling? Will it ignore the hollow interior and mill the exterior or will it try to mill inside and outside of image file?

From what I have , Cut3d will make the interior solid.
So, I'm guessing in your case, it will only mill the exterior shape and not the interior.
