2. How can visualizing help an engineer in the design process?
Visualization can help an engineer to mentally picture things that do not exist. Besides, engineers with good visualization ability are able to picture things in their minds. Furthermore, good visualization skills allow them to control mental image, allowing them to move around the image, change the form, look

11. Outline the three ways the 3-D model database can be used in the implementation phase.
Three ways the 3-D model database can be used in the implementation phase are production, marketing and service & documentation. Production is 3-D CAD models which are used to run machine tools and make parts and layout the factory floor. Marketing is 3-D CAD models are used for illustrations, presentation graphics, and advertising. Service & Documentation is 3-D CAD models are used for service manuals, training, and assembly instructions.

12. What kinds of documentation might be produced as part of the design process?
Design process documentation 2-D engineering drawings, 3-D design models, presentation drawings and illustrations.

13. Explain the role of PDM in the design process. What is the relationship of ERP to PDM?
Product Data Management (PDM) is the name given to specific computer-based tools and used to track CAD or office documents with user-defined data fields, such as revisions, authors, date, and so forth in the development and manufacture of a product. Within PDM, Enterprise resource planning (ERP) is a system that specifically focuses on the ordering of material and planning for the materials used for manufacture of a product.

14. What is the difference between conventions and standards?
Conventions commonly are accepted practices, rules, or methods. In technical drawing, an example of a convention is the use of
