This Mechanical Engineering textbook by R. B. Patil is designed for Semester III students at Maharshi Dayanand University (MDU). It covers Computer Aided Design (CAD), focusing on how computers are used to create, modify, and optimize engineering designs.

🖥️ Key Topics Covered

• Geometric Modeling: Mathematical representation of curves (like Bezier and B-Splines), surfaces, and solids.

• Transformations: Principles of 2D and 3D transformations, including scaling, rotation, and translation.

• CAD Hardware & Software: Overview of input/output devices, graphics standards, and database management for design.

• Visual Realism: Techniques for rendering, shading, and hidden line removal to create realistic models.
