As a design checker, you are responsible for examining the engineering drawings of parts, assemblies, and installations to ensure accuracy and completeness. You have interpretation duties to detect any errors or discrepancies within these 3D design documents. Your responsibilities require you to annotate any changes that need to be made and communicate with others how to pursue a better design for manufacturability. You consult for angles, dimensions, bend allowances, and tolerances to avoid mistakes during and after development. You also determine material and tool selection using your knowledge of drafting and manufacturing methods.
