Unformatted text preview: Introduction to Technical Sketches and Engineering Drawings Dr. Thomas E. Doyle, P.Eng Department of Electrical and Computer Engineering ETB/106 OfFce Hours are Mondays 2:00 -- 4:00pm Lecture Objectives • Geometry of Engineering Graphics • DeFne projection types: • Isometric • Multiview Sketching Elements • In technical sketching you will be creating drawings for the purpose of sharing ideas visually. • This is a critical skill in engineering design for all disciplines. • Balance quickness vs neatness - the goal is to communicate your idea efFciently. • All sketches will be comprised of two basic elements: • Lines • Curves (usually circular or elliptical) • You will learn to make two kinds of sketches: • Isometric (looks 3D) • Multiview (looks 2D) Faces, Edges, and Vertices • Any object can be defned by its boundary . This boundary is made up o¡ sur¡aces, called ¡aces . • Each ¡ace is bounded by edges . • Each edge is bounded by vertices . • Faces can be any mathematically defnable sur¡ace but we will usually restrict ourselves to planar, cylindrical, conical, and spherical sur¡aces....
