Engineering Drawing

Course Objectives:

● To impart knowledge on dimensions and drawing standards.

● To explore the orthographic projection of lines and solids.

● To provide the understanding of orthographic, isometric and perspective views.

Fundamentals: Drawing  instruments, Drawing   standards  (BIS), Lettering in engineering, Sheet layout, elements of dimensioning, Systems of dimensioning. Free hand sketching of 2D & 3D objects, Conics – Ellipse, Parabola and Hyperbola.

Activities: Virtual Demonstration of Conics and Cycloids.

Orthographic Projection: First angle projection, Projection of points, straight lines and planes.

Projection of Solids: Simple Solids, Section of Solids, Development of Surfaces

Activities: Development of models of various solids and virtual demonstration of sectioning, CAD modelling of 2D objects.
