What are the advantages and disadvantages of using CAD systems to create engineering drawings? correct answers Advantages of using CAD systems to create engineering drawings: Faster and more accurate geometric constructions. Engineering Drawings created by CAD systems can be re-used and modified faster. CAD drawings can be easily transferred through internet. Large number of CAD drawings can be easily moved, from one location to another, by using portable storage devices. A lot of the information stored in the CAD database can be re-used during the manufacturing processes. Disadvantages of using CAD systems to create engineering drawings: Initial cost to purchase CAD hardware and software can be quite high. Trainings are required to implement using the CAD systems, which may require additional time and money. Electronic format of CAD drawings are fragile as CAD files can be lost accidentally after a power failure, a hardware crash or even human mistakes. What is the default AutoCAD filename extension? correct answers .dwg How do the GRID and SNAP options assist us in sketching? correct answers The GRID and SNAP options can be used to provide a visual reference as to the size of objects and to restrict the movement of the cursor to a set increment on the screen. List and describe the different coordinate entry methods available in AutoCAD? In AutoCAD, there are five methods for specifying the locations of points when we create planar geometric entities. correct answers Interactive method: Use the cursor to select on the screen. Absolute coordinates (Format: X,Y): Type the X and Y coordinates to locate the point on the current coordinate system relative to the origin. Relative rectangular coordinates (Format: @X,Y): Type the X and Y coordinates relative to the last point. Relative polar coordinates (Format: @Distance<angle): Type a distance and angle relative to the last point. Direct Distance entry technique: Specify a second point by first moving the cursor to indicate direction and then entering a distance. When using the Line command, which option allows us to quickly create a line-segment connecting back to the starting point? correct answers The Close option List and describe the two types of coordinate systems commonly used for planar geometry. correct answers The two types of coordinate systems commonly used for planar geometry are the Cartesian coordinate system and the Polar coordinate system. Which key do you use to quickly cancel a command? correct answers Esc
