Whatare different types of Engineering drawing?
There are several types of engineering drawing that are used in different
contexts and for different purposes. Here are some of the most common types
of engineering drawing:
1. Orthographic Projection Drawings: These are 2D representations of a 3D
object, typically shown in two or more views (such as front, top, and side
views) to convey the shape and dimensions of the object accurately.
2. Isometric Drawings: These are 3D representations of an object that show
all three dimensions (height, width, and depth) at once, typically at a
120-degree angle.
3. Exploded Views: These drawings show an object that has been
disassembled into its component parts, with each part separated and
labeled for clarity.
4. Assembly Drawings: These are used to show how parts of a product or
machine fit together, with detailed instructions on how to assemble
them correctly.
5. Piping and Instrumentation Diagrams (P&ID): These are used to show
the piping and instrumentation systems used in industrial settings,
including details of pipes, valves, pumps, and other equipment.
6. Wiring Diagrams: These show the electrical connections and
components used in electrical systems, such as circuits or wiring layouts.
7. Structural Drawings: These are used to show the structural components
of a building or other structure, including beams, columns, and
foundations.
8. Patent Drawings: These are used to illustrate an invention or design for
the purpose of obtaining a patent.
Each type of engineering drawing serves a specific purpose and requires
different techniques and tools to create. Understanding the different types of
engineering drawings is important for communicating technical information
accurately and effectively.

Engineering Drawings (cam.ac.uk) (Engineering Drawing Types)
Engineering drawing, also known as technical drawing, is a form of technical documentation
that provides detailed information about a component, system, or structure. There are
several types of engineering drawings, including:
1. Architectural drawings: These drawings provide detailed information about
the design and layout of buildings, including floor plans, elevations, and
sections.
2. Structural drawings: These drawings provide detailed information about the
structural design of a building or other structure, including foundation
plans, framing plans, and details of structural elements.
3. Mechanical drawings: These drawings provide detailed information about
mechanical systems and components, such as HVAC systems, plumbing
systems, and machinery.
4. Electrical drawings: These drawings provide detailed information about
electrical systems and components, such as wiring diagrams, electrical
layouts, and details of electrical equipment.
5. Piping and instrumentation diagrams (P&IDs): These drawings provide
detailed information about the piping systems and instrumentation used in
industrial plants and facilities.
6. Flow diagrams: these diagrams are used to represent the flow of materials,
fluids, or energy in a process or system.
7. Assembly drawings: These drawings provide detailed information about
how various components are assembled to form a larger system or product.
8. Detail drawings: These drawings provide detailed information about
specific components or parts of a system or structure, including
dimensions, tolerances, and material specifications.
9. Isometric drawings: These drawings provide a 3D representation of an
object, it gives the viewer a better understanding of how the object looks
like and how it's constructed.
Overall, the type of engineering drawing used will depend on the specific project and the
information that needs to be conveyed.
