Steps in Creating the Three-View Sketch– Step 2 Lightly Block Major Features
Steps in Creating the Three-View Sketch– Step 3 Add Features, Use Miter Line
Summary • Multi-view drawing tools • Use of hidden and center lines • Conventions on line intersections • Precedence for line types • Two View Drawings - Multi-view drawings for objects with symmetry • Lettering • Creating a Three-View Sketch • Using the Miter Line to transfer dimensions between views
