I am a Mechanical Engineering student and my thesis requires me to model a hull of a ship, specifically an icebreaker and to be imported into ANSYS. The only CAD program that I'm good at is ProEngineer but I have no idea how to model a hull since this is more towards naval architecture, not machine or structure design. Can anyone assist or provide me links to tutorials to model a hull in ProEngineer? or maybe in Catia?
