These questions are designed to further your knowledge of AutoCAD by encouraging you to explore the concepts presented in this chapter Answer each question on a separate sheet of paper 1 Many zoom and pan variations have been introduced in the last two chapters Describe how and when you might use a combination of them, but explain also why it may be impractical to use all of them Which methods of zoom and pan are the fastest, and which seem to be the most practical for most applications 2 Is Aerial View an alternative to using the PAN command Explain when you would use each most effectively

Work the following problems to practice the commands and skills you learned in this chapter 1 Open the attribdwg le located in the Sample/ActiveX/ExtAttr folder Use AutoCAD s zoom feature to magnify the parts list located in the upper right area of the drawing Use realtime zoom and pan to study all the items on the list What is the part number of the Inner Plate How many rivets are required for the assembly
