I have a mesh file containing a fully enclosed cavity (due to a previous shell command). It seems like it should be pretty easy to fill it, but I'm not sure if there is a way to do it in fusion360 without converting it to a solid body. I'd rather not do that because it's a complicated mesh file, and I think the conversion would take too long. I basically want a thicken command for meshes or something similar. Any options?
