Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary function?To communicate design intent and manufacturing specifications with absolute clarity and precision
2. What is the core methodologies?Orthographic projection, isometric projection, and detailed dimensioning with tolerances
3. What is technical drawing and why is it important?Technical drawing is a precise visual language that shows how to build things, like rockets or cars. It lets engineers and builders see exactly how parts fit together and helps keep everything safe.
4. How did technical drawing change from hand drawings to computer programs?Early draftsmen drew plans by hand with special line types and symbols. Later, blueprints were made with photography, and now CAD software lets people create digital drawings that can be used for 3D printing and CNC machines.

Geometric Dimensioning and Tolerancing (GD&T): A symbolic language used to specify allowable variations in manufactured part features.
Parametric Modeling: A CAD technique where design features are linked to parameters, allowing for easy modification.
Bill of Materials (BOM): A list of all the components and materials required to manufacture an assembly.
