  3. FREE HAND SKETCHING SOLIDS Solid is a three dimensional object It has three dimensions (Length, Breadth and Height /Thickness) It is bounded by plane or curved surfaces Atleast 2 orthographic views are required to represent a solid on a flat surface Some times additional views are necessary to describe a solid completely Engineering Graphics Lecture Notes C.R.ENGINEERING COLLEGE Alagarkovil, Madurai - 625301 I - SEMESTER 28.09.2012

  4. FREE HAND SKETCHING • Solids can be divided into 2 main groups viz; • POLYHEDRA • -solids bounded by plane surfaces • such as Prisms, Pyramids etc… • SOLIDS OF REVOLUTION • -solids formed by revolution of linear figures • such as cylinder,cone and sphere Engineering Graphics Lecture Notes C.R.ENGINEERING COLLEGE Alagarkovil, Madurai - 625301 I - SEMESTER 28.09.2012

  12. TYPES OF PROJECTION Engineering Graphics Lecture Notes C.R.ENGINEERING COLLEGE Alagarkovil, Madurai - 625301 I - SEMESTER 28.09.2012

  13. ORTHOGRAPHIC PROJECTION DEFINITION Method of representing the exact shape of an object in two or more views, on planes always “at right angles to each other” by edtending perpendiculars from the object to the planes. It is universally used in engineering drawing The word “ORTHOGRAPHIC” means to draw at right angles Different views of an object are obtained to describe with all dimensions It is classified into 4 categories according to the orientation of the object. But only Ist angle and IIIrd angle projections are used in engineering drawing. Engineering Graphics Lecture Notes C.R.ENGINEERING COLLEGE Alagarkovil, Madurai - 625301 I - SEMESTER 28.09.2012
