For Mechanical Engineering Sandwich 8th Sem scheme and its subjects, do visit Mech Sandwich 8th Sem 2021 regulation scheme. The detailed syllabus of cad or cam laboratory is as follows.

Course Objectives:

1. To gain practical experience in handling 2D drafting and 3Dmodelling software systems
2. Designing 3 Dimensional geometric model of parts, sub-assemblies, assemblies and exporting it to drawing
3. Programming G & M Code programming and simulate the CNC program and Generating part programming data through CAM software

3D Geometric Modelling

1. CAD Introduction

Sketch:
Solid modeling: Extrude, Revolve, Sweep, Variational sweep and Loft.
Surface modeling: Extrude, Sweep, Trim, Mesh of curves and Free form.
Feature manipulation: Copy, Edit, Pattern, Suppress, History operations.
Assembly: Constraints, Exploded Views, Interference check
Drafting: Layouts, Standard & Sectional Views, Detailing & Plotting

2. Creation of 3D assembly model of following machine elements using 3D Modelling software
