Whenever trying to start a manufacturing project, mechanical design is a must. When dealing with physical products, there are many situations where you will need specifications on a draft. They will be needed for creation and development, prototype design, patent drawings, production, etc.
All of these steps require mechanical drawings to be made before bringing any product to the market and depending on the complexity, mechanical designs usually require significant experience to be elaborated properly.
You’ll eventually need mechanical drawings if you’re an inventor, or have an idea for a new product. If you need product design documents, patents, or just design specifications.
A mechanical drawing is a type of technical drawing used to visually communicate how mechanical components and machines function, and facilitate their construction.
Technical drawings function like a language; they begin with the understanding of graphical projection, and have the intention of representing a three-dimensional object on a two-dimensional surface in a certain way, so that another person or software can understand all the properties of the part.
