Technical drawing is important because it helps companies visualize a concept so that it can be easily communicated for production into a physical item. Companies use technical drawings for both prototypes of items and the final version for production. These drawings need to be detailed and follow any specifications required in the industry, such as in engineering.
Technical drawings are often made using computer software such as SolidWorks or AutoCAD, and they can be two-dimensional or three-dimensional drawings. The engineers doing the drawings typically follow a process that involves developing a drawing in the software, analyzing the structure of the model, creating a virtual prototype, testing the prototype to make sure it would function correctly and meet the specifications, and then performing a final analysis.
