Rationale:

The contemporary progressing world is fast with the latest production systems. The advanced manufacturing of products is developed instantly using CAD Software. Even a small scale industry is now using CAD software as it has become the heart of the Design department. So CAD has now become inevitable in industries.

Accuracy and Precision are the two important things that decide the quality of a product to survive its competitors in the market. Using CAD software design, the uniform accuracy, multiples of copies and storing in a small space for long time are assured.

The CAD software considerably improves the creativity and flexibility of a designer. The syllabus here enables a candidate to draw an industrial drawing within the optimum reach of a diploma cadre.

Objectives:

• Appreciate the need of sectional view and types of sections.
• Draw sectional views using different types of sections.
• Explain the use of threaded fasteners and the types of threads.
• Compare hole basis system with shaft basis system.
• Select different types of fits and tolerance for various types of mating parts.
• Practice on CAD commands in making 2D Drawings.
• Draw assembled drawings of different types of joints and couplings using CAD.
• Draw assembled drawings of various types of machine elements using CAD.
