COMPUTER AIDED DESIGN & DRAFTING LAB

Lab Incharge: Mr. Anil Gupta

Technician: Mr. Piyush Motwani

Lab Overview:

The Computer-Aided Design and Drafting (CADD) Lab is a state-of-the-art facility designed to equip students with expertise in CAD modeling, 2D-3D transformations, and advanced drafting techniques. This lab integrates modern CAD software, high-performance computing resources, and interactive learning tools to provide students with a practical understanding of engineering design, solid modeling, and finite element analysis (FEA).

By working with industry-standard CAD tools and real-world mechanical components, students develop essential skills in curve representation, surface generation, solid modeling, and data exchange between CAD/CAM systems, preparing them for cutting-edge design and manufacturing applications.

The lab is fully equipped, LAN-wired, and well air-conditioned, ensuring a comfortable and conducive learning environment for students.
