Technical illustrations are an important part of the design process, it is this documentation that becomes the language spoken by engineers and manufacturers during production.
A miscommunication at this stage could be costly, this is where digital design becomes noticeably more beneficial. Once a three dimensional model has been created, developed and tested, the same model is used to create the 2D drawings. This ensures all the design elements are captured in detail ready for the manufacturer.
