    Engineering Drawing—-ISOMETRIC PROJECTIONS

    Engineering Drawing—-ISOMETRIC PROJECTIONS ISOMETRIC PROJECTION  It is 3-dimensional view of an object on a reduced scale. Sizes on this are 81.5 % of the true sizes. These are drawn from given front view, top view and side view. There are only true dimensions on the front, top and side views.   ISOMETRIC AXES  In this, […]

    Engineering Drawing—-DEVELOPMENT OF SURFACES

    Engineering Drawing—-DEVELOPMENT OF SURFACES DEVELOPMENT OF SURFACES Cut the one surface of the solid and open it to layout on a sheet of paper is called development of surfaces. It is used in surfaces made out of a sheet. It should be insured that every line on the development gives the true length. METHODS OF […]

    Engineering Drawing————-INTERSECTIONS OF SURFACES

    Engineering Drawing————-INTERSECTIONS OF SURFACES INTERSECTIONS OF SURFACES It means that one surface is entering another surface OR A surface is to be connected to another surface. It may be easy to connect any shape object into a plane wall. But it is very difficult for curved surfaces. For example a pipe is to be connected […]


  • ENGINEERING DRAWING—-SECTION OF SOLIDS

    ENGINEERING DRAWING—-SECTION OF SOLIDS

    ENGINEERING DRAWING—-SECTION OF SOLIDS SECTION OF SOLIDS Section views are a very important for designing an object or a machine. Section of solids improve clarity and reveal interior features of parts which are other wise not visible. Sections of solids are based on the use of an imaginary cutting plane to reveal the interior details. Its importance increases […]

    ENGINEERING DRAWING—-PROJECTIONS OF SOLIDS

    ENGINEERING DRAWING—-PROJECTIONS OF SOLIDS  PROJECTIONS OF SOLIDS WHAT IS A SOLID? ANS: Every solid phase substance in the universal is 3-dimensional. Hence every solid substance is a solid. For example, book, wall, table, chair, fan, pen etc. TYPES OF SOLIDS—-TWO TYPES Polyhedra (Regular polyhedral Have number of faces, equal and regular, ir-regular polyhedral which unequal […]

    Engineering Drawing———Projections and Traces of a plane

    Engineering Drawing———Projections and Traces of a plane PROJECTION OF PLANES In actual practice, one is interested to draw the projections of a solid. But it is started with the projection of points. Number of points makes a line, then projections of a line is done. Lines form planes and hence then projections of a plane […]
