Start with the way your part will be used
A model file describes shape, but a useful manufacturing brief also describes the job the part must do. Tell us whether it is a presentation model, an assembly fixture, a protective sleeve or a component that will be handled repeatedly. Explain what it touches, which faces are visible and whether heat, moisture or outdoor exposure matter. We review orientation, supports and finishing against that application, rather than selecting settings solely to minimise the estimated price. Critical dimensions belong on a drawing so the acceptance criteria are explicit.
