drafting symbolsEngineering drawings are technical diagrams and representations meant to define parameters and other plans for something that is to be engineered. This is also known as drafting, and can be used in the fields of civil engineering, architecture, carpentry, landscaping, and so on. Technical drawings are much more than just simple diagrams, though – it is its own language with a set of conventions, including symbols and other markings used to designate specifics.

If you’re studying engineering and need a reference sheet for these drafting symbols, you’ve come to the right place. This guide will list some of the need-to-know drafting symbols, and provide some resources for your studies. Not sure where to start?
