EXAMPLES AND EXERCISES ORTHOGRAPHIC PROJECTION mod- 1 - ORTHOGRAPHIC PROJECTION Orthographic or Orthogonal Projection or sometimes called Working Drawing is a system of drawings obtained in which the object is viewed at right angle and projected on to a perpendicular plane. 2.2.1) The Six Principle Views The 6 principle views of an orthographic projection are shown in Figure 2-2. Orthographic Projections • Orthographic Projections are a collection of 2-D drawings that work together to give an accurate overall representation of an object. Projections • Behind every 2D drawing of an object is a .

STEP 1 First of all observe the isometric object given to you. General Guidelines • Pick a Front View that is most descriptive Students learn how to create two-dimensional representations of three-dimensional objects by utilizing orthographic projection techniques. Figure 7 identifies the possible orthographic projection views that could be used to represent an elbow fitting. (In Greek : … They build shapes using cube blocks and then draw orthographic and isometric views of those shapes—which are the side views, such as top, front, right—with no depth indicated. Prof. Krishna Jonnalagadda ME 119: ENGINEERING DRAWING 1.ORTHOGRAPHIC PROJECTION (SOLUTION) PROBLEM 1: Draw the front view, top view and a suitable side view of the object given below. involving the object and three “ imagined” things: – The observer’s eye, or station point – The plane of projection – The projectors (also called visual rays or lines of sight) Chapter 2: Orthographic Projection 2 - 2 Figure 2-1: Orthographic projection. Draw the projection lines and complete the front view. Which Views to Present? ORTHOGRAPHIC PROJECTIONS: Horizontal Plane (HP), Vertical Frontal Plane ( VP ) Side Or Profile Plane ( PP) Planes. •Orthographic projections are an engineer’s language for conveying the shape and size information about the products he designs. ! "# "$ "˜ ˝ ˇ˛% ˆˆ& ˝ ˆˆ " # ’ . Defining the Six Principal Views or Orthographic Views. Normally the longest dimension is chosen as the width (or depth) ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 157fd0-Mjc1M orthographic projections of an actual piping system. • The parallel rays that are used for constructing the views are called projectors. • An orthographic projection consists of the view obtained view when the object is viewed from very far away, so that the resulting rays are all parallel. The challenge of creating piping orthographics is that symbols must be used to represent 90° elbows or tees pointing toward or away from the viewer.
