![]() Q3: What are the two fundamental methods of shape representation used in engineering drawing?Ī3: Theory of projection is the base for the background information necessary to shape representation in graphics. Final design is then reproduced and sent to the job site or the shop. Engineering work is completely based on this method of projection. Where as, mutli view projection is a procedure that can be used to completely describe an object’s dimension or shape using two or more (multi) views that are normally projected at 90 degree to each other or at any other specified angles. Orthographic projection is the basis of all descriptive geometry procedures. To convey ideas, shapes, dimension, procedures, for the manufacture or the construction, drawings are used in engineering. Eccentric circles: Two or more circle with out a common or same center pointĪ2: Primary means of graphic communication which is used in engineering work is called multi view orthographic projection.Concentric circles: Two or more circles with a same center point. ![]() Segment: Smaller portion of the circle which is separated by the chord.Chord: A straight line whose opposite ends terminate on the circle.Quadrant: A sector with a central angle of 90 degree and with one of the radial lines oriented horizontally.Sector: Area of a circle lying between two radial lines and the circumference.A central angle: An angle formed by two radial line from the center of the circle.It is used to set the compass when drawing a diameter Radius: The distance between the center point and the outside curved surface is called radius.Diameter: The straight distance from a outside curved surface to the opposite outside curved surface through the center point. ![]() Q1: What is a circle and its components while considering engineering drawing?Ī1: A closed curve which has a center point and all the points on the curve are at the same distance from the center point.
