In Technical work, we utilize different drawings commonly known as Technical Drawings that can represent the design parameters, characteristics, connections of devices, and buildings that the drawings represents.

Through these drawings, it allows engineers and technical people to communicate ideas.

"Technical drawing is essential for communicating ideas in industry and engineering. "

"To make the drawings easier to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout."

These is essential since through these drawings an engineer or a technician can study the design and makeup of these devices, buildings or circuits even before he /she had the opportunity to see the device, building it self.

Types of Technical Drawing can be be grouped in two, the two-dimensional and three dimensional drawings.

Two dimensional drawings represents an image where only two of the three dimensions of the object are seen, while in a three-dimensional drawing, all three dimension of a drawing can be seen.

Since this Qualification, Computer Systems Servicing NC II, falls under the Electrical / Electronics Sector, I will be focusing more on the type of technical drawings that are normally used under this sector.

An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project," for Electronic works however a circuit diagram is commonly used.

"Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job."

For a circuit diagram, it is a combination of  pictures with symbols (fig 1) that can differ from country to country and have changed over time, but as of now, to a large extent, it is internationally standardized. 

For my next blog, we will delve more on schematic symbols and Diagrams, till then. Cheers.
