Role of Engineering Drawing: The engineering drawing subject is designed to impart the following skills: 1. Ability to read and prepare engineering drawings. 2. Ability to make free - hand sketching of objects. 3. Power to imagine, analyze and communicate. 4. Capacity to understand other subjects.
used for preparation of drawings. • Standards – set of rules for preparation of technical drawings. Conventions – commonly accepted practices in technical drawings. • Tools – devices used to create technical drawings and models. • Applications – the various uses for technical drawings.
Slide 1. TISHK INTERNATIONAL UNIVERSITY SURVEYING AND GEOMATICS ENGINEERING DEPARTMENT. Engineering Drawing II. Lecture 2. Orthographic Projection. Projection. Behind every drawing of an object is a space relationship involving four imaginary things: The observer’s eye or the station point. The object. The plane of projection.
This handbook is devoted to provide general aspects of engineering drawing like lettering, geometric constructions, dimensioning, scaling, orthographic and isometric projections and sectioning. The handbook is prepared taking aid from a number of textbooks and articles mentioned in bibliography section.
Drawing an arc tangent to a given point on the line Steps • Given line AB and tangent point T. Construct a line perpendicular to line AB and through point T. • Locate the center of the arc by making the radius on the perpendicular line. Put the point of the compass at the center of the arc, set the compass for the radius of the arc, and ...
The purpose of this guide is to give you the basics of engineering sketching and drawing. We will treat “sketching” and “drawing” as one. “Sketching” generally means freehand drawing. “Drawing” usually means using drawing instruments, from compasses to computers to bring precision to the drawings. This is just an introduction.
From points A and B, draw lines parallel to the minor diameter. Draw lines parallel to the major diameter through D & E. The intersection of the lines from A and D is point F, and from B and E is point G. Points F & G lies on the ellipse.
