What is Engineering Graphical Communications?

• According to the MEC222 course textbook, it is a “complete language used in the design process for visualization, communication, and documentation”

Why is Engineering drafting a useful skill?

• DWG’s help you to convey your message to a broad spectrum of people:• Engineers inside your field of expertise• Engineers outside of your field of expertise• Technical Professionals (Technicians/Laboratory staff)• Lay (non-technical/non-Engineering) People

• Medical Professionals• Officers• Judicial Figures

Which one should we use?

Manual Drawings

• Creating concept models

• Organize your ideas for use in solid modelling

• In situ visual aids (shop floor)

CAD Station

• Documentation versioning

• Virtualization and visualization (FEA)

• Manufacturing validation (Fit and Function)

• CAM
