I have an organic object, let's say it's a bone like the tibia. I want to create a box on top of that bone. I have the .iges file of the bone. How do I generate a cube with one face that conforms the top of the bone? For context, I know how to turn the iges file into a tetra mesh but I am not quite sure how to create a box with a conforming face to the bone. Would anyone have an idea how to pull this off? I want to do this in only Hypermesh because I am already using multiple programs in my project.
