Engineering Drawing “Design is the process of conceiving or inventing ideas and communicating those ideas to others in a form that is understood easily.”
PROBLEMS 7.1 A cone of base diameter 3-in and height 3.5-in is sectioned by a plane at an angle of 45 with the axis of the cone at a height of 2-in. Draw development for the truncated cone. 7.2 A cone of base diameter 6-in having an altitude of 5-in is penetrated on one side by […]

DEVELOPMENT OF SURFACES When a curved surface is unfolded to a single plane, the resulting figure is called development of that surface. By using these surface developments a pattern layout of any object can be constructed on some plane sheet which may then be used to form the required shape. Application of surface developments are

INTERSECTION OF SURFACES While making orthographic drawings, the intersections between the various types of surfaces are to be shown by certain lines. For example, when two planes intersect, a straight intersection line is obtained. Intersection of surfaces especially means the complicated lines obtained when geometric shapes such as planes, cylinders, prisms, pyramids and cones intersect

COMMON TYPES OF SURFACES Prism A prism is a polyhedron (shape with multiple faces) having identical and parallel bases (or ends) connected by lateral laces which are parallelograms. The axis of a prism is a straight line connecting the centers of the bases. Pyramid A pyramid is a polyhedron whose base is a polygonal plane

INTERSECTION AND DEVELOPMENT OF SURFACES SURFACES A surface is a geometric shape having two dimensions with negligible thickness but it may lie in a three dimensional space. The surface may be formed/generated by moving a line, called the GENERATRIX of the surface. Any position of the generatrix is an element of the surface. The line

PROBLEMS 6.1 Observe different types of boundary walls constructed for houses and offices. Select one which you prefer architecturally, function-wise, and from economic point of view. Measure the visible part of the wall, suggest changes if you like, and complete it by providing suitable foundation. Make rough sketches for Plan,. Section and Elevation and discuss these

CONSIDERATIONS FOR ARCHITECTURAL DESIGN OF A HOUSE The arrangement of various rooms in a building plan for easy and comfortable living of the occupants is called architectural design of the building. Every effort is made to utilize full natural resources such as wind, sun, etc. Maximum facilities are to be provided within the funds and

DRAWING OF A BUILDING After having practice to draw plan, section and elevation for important features of a building, drawing of a small typical building may be started. A single room building may serve the purpose of a shop, clinic, cafeteria or a filling station office, etc. Two- room building may serve the purpose of
