UPDATED ACTUAL Questions and
CORRRECT Answers
What are the advantages and disadvantages of using CAD systems to create engineering
drawings? - CORRECT ANSWER - 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 ANSWER - .dwg
How do the GRID and SNAP options assist us in sketching? - CORRECT ANSWER - 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 ANSWER - 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 ANSWER - The Close option
List and describe the two types of coordinate systems commonly used for planar geometry. -
CORRECT ANSWER - 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 ANSWER - Esc
When you use the Pan command, does the coordinates of objects get changed? - CORRECT
ANSWER - The Pan command enables us to move the screen view to a different position.
This function acts as if you are using a video camera. But it does not change the coordinates of
objects.
Find information on how to draw ellipses in AutoCAD through the InfoCenter and create the
following arc. If it is desired to position the center of the ellipse to a
specific location, which ellipse commands is more suitable? - CORRECT ANSWER - The
Center Ellipse command
Find information on how to draw arcs in AutoCAD through the InfoCenter and create the
following arc. List and describe two methods to create arcs in AutoCAD. - CORRECT
ANSWER - To create an arc, we can specify combinations of center, endpoint, start point,
radius, angle, chord length, and direction values.
3 points arc: Draws an arc using three specified points on the arc's circumference.
, The first point is the start point. The third point is the endpoint. The second point is a
point on the circumference of the arc.
Center, Start, End arc: Draws an arc using three specified points; the first point is
the Center point, the second point is the start point and the third point is the endpoint. (end of
chapter 1)
Describe the procedure to activate the AutoCAD Startup option.
The startup dialog box can be activated through the use of the STARTUP system
variable. - CORRECT ANSWER - The STARTUP system variable can be set to either 0
or 1:
1: displays the Create New Drawing dialog box.
0: displays the Select Template dialog box (default).
List and describe three options in the AutoCAD Object Snap toolbar. - CORRECT
ANSWER - The Snap to Endpoint option allows us to snap to the endpoint of an existing
line
or arc.
The Snap to Tangent option allows us to snap to the point on a circle or arc that,
when connected to the last point, forms a line tangent to that object.
The Snap to Center option allows us to snap to the center point of an existing circle
or arc.
Which AutoCAD command can we use to remove a portion of an existing entity? - CORRECT
ANSWER - Trim command
Describe the difference between the circumscribed and inscribed options when using the
AutoCAD Polygon command. - CORRECT ANSWER - Inscribed in Circle: Specifies the
radius of a circle on which all vertices of the
polygon lie.
Circumscribed about Circle: Specifies the distance from the center of the polygon
