ROLE OVERVIEW:
Draughtsmen Mechanical create detailed assembly drawings, engineering layouts, and 3D CAD models of machinery parts and tooling equipment.

SKILLS REQUIRED:
- 2D drafting and layout design using CAD software
- 3D parametric modeling and assembly structures
- Interpreting GD&T symbols on engineering prints
- Understanding mechanical manufacturing processes

TOOLS USED:
- CAD workstations running AutoCAD, SolidWorks, or Catia
- Drafting instruments, layout boards, and digital calipers

GROWTH PROSPECTS:
Technical pathway leading to CAD Designer and Mechanical engineering cell roles.

INTERVIEW QUESTIONS:
1. Q: What does GD&T stand for and why is it important?
A: Geometric Dimensioning & Tolerancing (GD&T) is a system of symbols used to specify size, shape, and orientation of features on engineering drawings.
2. Q: Explain the difference between 1st angle and 3rd angle projection.
A: In 1st angle, the object is placed between the observer and projection plane; in 3rd angle, the projection plane is between observer and object.
