Electrical Engineering Drawings

No. You just need to know what all the little squiggles mean.

How to Read a Schematic

Yes, there is a special technique to reading a technical drawing, its called a formal education in that technical field.

Now there are a few common traits to nearly all technical drawings that happen mostly in what's called the legend of the drawing. The legend will typically be in one corner of the document. In the legend will be the name of the drawing, an identifying drawing number or file location designation, the name of the company/individual that fabricated the engineering of the object and drawing along with a date that everything initially was approved by the responsible individuals, the latest revision designation that this document identifies. Often in the legend there will also be some specifications like the assumed tolerances, environmental conditions, other pertinent document identifications. Elsewhere on the document there maybe a listing, brief description, date, and authorization of the earlier revisions to this document.

Now the substance of the engineering document will require the formal training mentioned earlier to do a proper understanding of what the assembled symbols mean. For myself with my education I'm expected to know everything that a circuit built to an electronic schematic will do to the electrical signals applied to them. But the architectural drawings of a building will only tell me where electronic equipment and cabling can be placed. I cannot tell if the roof is over or under supported from the most complete architectural drawing.

Hi Dear,

I think the best thing you can do is to take a training course regarding "how to read the technical drawings", such courses are available online and on-site... also try to make use of your peers' knowledge if you work,study..........

i hope this helps.........
