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".

There are college or university courses in graphic engineering. For instance the Camosun College in British Columbia offers a Certificate in Engineering Graphics Technician. Information is also available from Wikipedia, or from your local public library.

There isn't much difference tho but first of all, with regards to the professionals involved... Civil engineering works- qualified civil engineering Building works- quantity surveyor (cost engineer) Will share more soon...
The number 162e-06 in standard engineering notation can be expressed as 162 micro (μ). In this format, it is written as 0.162 mill (m) or 162,000 nanometers (nm), depending on the context or the unit of measure being used.

It is always better to make the drawings as per some recognized standard. The engineering drawings normally use letters, symbols and short forms to make the drawing more readable. To avoid any confusions to an external party (a component supplier company - it could be even from another country, or even the customer) regarding the meaning of these symbols, notations short forms etc. also making a standardized format for drawings make it easy for anyone to understand the drawing. They can easily understand where to look for the Title block, Notes general tolerances etc.
Double line drawings in a pneumatic schematic represent the piping and tubing connections in a pneumatic system. The two lines indicate the boundaries of the pipes, distinguishing them from other elements like valves or cylinders. This notation helps clarify the flow paths and connections, making it easier to understand the system's operation and design. It’s a standard practice in engineering drawings to enhance the readability and communication of system layouts.

An isometric view is a two-dimensional representation of a three-dimensional object where the three principal axes are equally foreshortened, typically at 120 degrees to each other. In standard practice, isometric drawings do not depict perspective; instead, they maintain scale along the axes, allowing for accurate measurements. This type of projection is commonly used in technical and engineering drawings to provide a clear and comprehensive view of an object's dimensions and structure.
Either a job on one of the recognised professions (eg engineer, medic, scientist, accountant) or a job of work done to what would be recognised as a professional standard.
A standard can mean many things. In mathematics, the standard unit of length measurement in the metric system is the metre. In weight, the standard is the kilogramme. Basically a standard is an internationally recognised unit, by which all measurements in the same situation are compared.
A housing lot is not an internationally recognised standard measure.
