Symbols on engineering drawings are standardized representations that convey specific information about features, materials, and processes without the need for extensive text. They can indicate dimensions, tolerances, surface finishes, welding requirements, and other critical details essential for manufacturing and assembly. Understanding these symbols ensures clear communication between engineers, manufacturers, and contractors, facilitating accurate interpretation and execution of design intent.
There are different national and international standards for symbols and abbreviations. You will need to check out the national standards for the drawings you are referring to.
In architectural or engineering drawings, it is the symbol for diameter
The simplest answer is that working to a standard means that anyone can read the drawing. If there is no standard the symbols used on the drawing (weld type and size, surface finish, even the dimensioning of the components) would vary from one drawing (or draughtsperson) to another and cause confusion. Engineering drawings use a large number of symbols to denote operations and instructions (which reduces the time taken to draw them and the size of "paper" they're drawn on). Imagine the potential problems if one person used a symbol to mean "weld" and another one used the same (or similar) symbol to mean "do not weld".

It depends on what type of engineering drawings. If you want cutsheets for equipment, most manufacturers have drawings on their websites. But if you are looking for construction or assembly drawings manufacturers or companies will not have them available outside the company since these would be intelectual property.
Various systems of coding drawings include Architectural, Engineering, and CAD (Computer-Aided Design) standards. Architectural drawings often use symbols and annotations to represent building elements, while engineering drawings follow specific conventions like ISO or ASME standards for precision and clarity. CAD systems employ layers, blocks, and attributes to organize and manage complex designs digitally. Additionally, graphic coding systems like UML (Unified Modeling Language) are used for software and systems engineering to visually represent structures and processes.
cus if you draw drawings then you draw draweings alot more often
Yes, AutoCAD is used in many engineering fields to create drawings and plans.
Fabricators typically use a variety of engineering drawings, including detailed fabrication drawings, assembly drawings, and shop drawings. Fabrication drawings provide precise specifications for individual components, while assembly drawings illustrate how these parts fit together in the final product. Shop drawings serve as a bridge between the design intent and actual production, detailing how to manufacture and assemble components efficiently. Together, these drawings ensure accuracy, consistency, and clarity throughout the fabrication process.
In drawings, the symbol frequently used to represent all metals is the triangle. This symbol is often seen in various engineering and architectural schematics to denote metallic materials, especially in conjunction with other symbols that specify particular types of metals or alloys.
I don't use engineering drawings.... I guess?!
