When cleaning and simplifying Inventor models for layout purposes simplify command is great tool to be used. Anyhow when there are sheet metal parts included and round surfaces of bending removed there are generated complex 3D surfaces in case of non orthogonal plates. Now these can be removed by using Delete Face command but the default setting of Heal remaining faces is off. Could the default be ON instead of OFF? Certainly it would be also great if the simplify command would bit better job in these cases.
