Key Takeaways:

Types of Drafting

Drafting can be classified based on the industry and purpose of the technical drawing.

Mechanical Drafting ⚙️
Used for machine parts, assemblies, tools, and manufacturing drawings.
Architectural Drafting 🏠
Used for floor plans, elevations, sections, and building construction drawings.
Civil Drafting 🏗️
Used for roads, bridges, site plans, drainage, grading, and infrastructure.
Electrical Drafting ⚡
Used for electrical circuits, wiring diagrams, panels, and electrical layouts.
Structural Drafting
Used for structural components such as beams, columns, foundations, and steel structures.
Piping & P&ID Drafting
Used for pipelines, valves, equipment connections, and process systems.
Plumbing & HVAC Drafting
Used for water supply, drainage, heating, ventilation, and air-conditioning layouts.
Electronics Drafting
Used for circuit boards, electronic components, and schematic diagrams.

Summary

Mechanical → Architecture → Civil → Electrical → Structural → Piping → HVAC/Plumbing → Electronics

Today, most of these drafting types are created using CAD software, such as AutoCAD, SOLIDWORKS, CATIA, and Revit.
