Engineering Graphics and Design

Welcome to the Engineering Graphics and Design Laboratory!

This laboratory is designed to help students develop the ability to visualize, draw, and interpret engineering components and assemblies. It focuses on enhancing spatial imagination, drafting skills, and the application of engineering standards in technical drawing and computer-aided design (CAD).

Students will learn both manual drafting techniques and CAD-based modeling, bridging the gap between traditional engineering drawing and modern digital design practices.

Laboratory Infrastructure

1. 1. Comprehensive Equipment
      • Drawing Boards with T-squares and Mini-Drafters for manual sketching and drafting.
      • Set Squares, Protractors, Compasses, and French Curves for geometric constructions.
      • High-quality Drawing Sheets, Pencils, and Templates for precise manual work.
      • Computer Workstations with licensed CAD software such as AutoCAD.
      • Large Format Printers/Plotters for printing engineering drawings.
      • Projection Models and Mechanical Part Samples for 3D visualization practice.
   2. Hands-on Learning
      • Orthographic projection, isometric views, and sectional views.
      • Create dimensioned engineering drawings using BIS/ISO standards.
      • Convert freehand sketches into accurate technical drawings.
      • Develop 3D CAD models and generate 2D views from them.
      • Interpret and modify engineering drawings for manufacturing.
   3. Learning Outcomes
      • Understand and apply engineering drawing standards in technical documentation.
      • Visualize and represent 3D objects in 2D form using projections.
      • Prepare detailed and assembly drawings manually and using CAD tools.
      • Interpret engineering drawings for manufacturing and inspection.
