PLANE CURVES, PROJECTION OF POINTS, LINES AND PLANES
Importance of graphics in design process, visualization, communication, documentation and drafting tools, Construction of curves - ellipse, parabola, and hyperbola by eccentricity method only. Orthographic projection of points. Projections of straight lines located in first quadrant - determination of true length and true inclinations. Projections of plane surfaces - polygonal lamina and circular lamina, located in first quadrant and inclined to one reference plane.
PROJECTION AND SECTION OF SOLIDS
Projection of simple solids - prism, pyramid, cylinder and cone. Drawing views when the axis of the solid is inclined to one reference plane. Sectioning of simple solids - prisms, pyramids, cylinder and cone. Obtaining sectional views and true shape when the axis of the solid is vertical and cutting plane inclined to one reference plane.
DEVELOPMENT OF SURFACES, ISOMETRIC PROJECTIONS AND FREE-HAND SKETCHING
Development of lateral surfaces of truncated prisms, pyramids, cylinders and cones. Isometric projection, Isometric scale, Isometric views of simple solids, truncated prisms, pyramids, cylinders and cones. Free hand sketching techniques, sketching of orthographic views from given pictorial views of objects, including free-hand dimensioning.
INTRODUCTION TO AUTOCAD
Introduction to Drafting Software (AutoCAD) & its Basic Commands. Introduction to coordinate systems, object selection methods, selection of units and precession. sketching – line, circle, arc, polygon, rectangle and ellipse. Working with object snaps, layers and object properties. Editing the objects – copy, move, trim, extend, working with arrays, mirror, scale, hatch, fillet and chamfer.
ISOMETRIC VIEWS WITH AUTOCAD
Building drawings – Single and double bed room house (sectional Top view only). Introduction to Motion path animation. Isometric views of simple solid blocks.
