TAILIEUCHUNG - Lecture Engineering drawing and design - Lecture 3: Pictorial projections

Lecture Engineering drawing and design - Lecture 3: Pictorial projections. The learning objectives for this chapter include: How to represent a 3-D object effectively on a 2-D drawing surface with a single view (pictorials), how to generate pictorials using only hand drawing tools, recognize types of pictorials. | Design web Design web Objectives for today ME 1110 – Engineering Practice 1 Engineering Drawing and Design - Lecture 3 How to represent a 3-D object effectively on a 2-D drawing surface with a single view (pictorials) Pictorial projections How to generate pictorials using only hand drawing tools Prof Ahmed Kovacevic School of Engineering and Mathematical Sciences Room C130, Phone: 8780, E-Mail: 1 Recognize types of pictorials Ahmed Kovacevic, City University London 2 Ahmed Kovacevic, City University London Design web Design web Exercise DrE-2 for this week 3 Ahmed Kovacevic, City University London 4 Ahmed Kovacevic, City University London Design web Design web Pictorials Definition: A sketch developed for ease of visualization that shows an objects height, width, and depth in a single view Particularly useful for non-technical audiences » Pictorials are generally not dimensioned » Surfaces are often shaded » Hidden lines are not shown Helpful in the ideation phase of design May be easily drawn with CAD programs 5 Ahmed Kovacevic, City University London 6 Ahmed Kovacevic, City University London Design web Design web Pictorials Parallel Projection » Oblique Pictorials – Parallel projectors are not perpendicular to the projection plane » Axonometric Pictorials Pictorials – Projection lines are perpendicular to the projection plane as in a multiview drawing – Example is Isometric Perspective Projection » Conveys information about distance and size » Not as common as parallel projection 7 Ahmed Kovacevic, City University London 8 Ahmed Kovacevic, City University London Design web Design web Axonometric views 9 Theory of isometric projection Ahmed Kovacevic, City University London 10 Ahmed Kovacevic, City University London Design web Design web Size Isometric projection - drawing 11 Ahmed Kovacevic, City University London 12 Ahmed Kovacevic, City University
