AutoCAD Fundamentals — 75 Task-Based Exercises with
Screenshots New 2025/2026 Updated
Why is learning lines and circles the first two geometric en es that should be learned first? -
Answers Because straight lines and circles are used almost in all technical designs.
All CAD systems created designs using basic geometric ______________ and many of the
construc ons used in in technical designs are based upon what? The method and number of
opera ons that are required to accomplish the basic planar construc ons are __________ from
one CAD system to another. - Answers en es/planar geometry/different
Every object we construct in a CAD system is measured in ____________. - Answers units
What should we determine before we create the first geometric en es in autoCAD? -
Answers The system of units.
How do you select the system of units? - Answers In the Menu Bar select: Format, Units, then
set preferences.
What is meant by se/ng the drawing limits? - Answers Se/ng the drawing limits controls the
extents of the display of the grid. It also serves as a visual reference that marks the working
area. It can also be used to prevent construc on outside the grid limits and as a plot op on that
defines an area to be plo3ed/printed. Not that this se/ng does not limit the region for
geometry construc on.
How do you set the drawing limits? - Answers In the Menu Bar select: Format, Drawing limits,
then ENTER to accept lower le6 corner and then ENTER again to accept upper right corner.
What does the Zoom All command do? - Answers Adjusts the display so that all objects in the
drawing are displayed to be as large as possible.
, What does the F7 key do? - Answers Turns on or off the display of grid lines.
The op on bu3ons in the status bar can be switched on and off in the ___________ of another
command. - Answers middle
What is the grid? - Answers A pa3ern of lines or dots that extends over an area on the screen
and used as a reference for aligning objects and visualizing distance between them.
The grid is not ___________ in the plo3ed drawing. - Answers displayed.
What is snapmode? - Answers A mode that controls an invisible rectangular grid that restricts
cursor movement to specified intervals. When SNAPMODE is on, the screen cursor and all input
coordinates are snapped to the nearest point on the grid. The default snap interval is .5 inches
and aligned to the grid points on the screen.
How do you deselect an object from the selec on set? - Answers hold down the SHIFT key and
select the object to be removed.
What the autoCAD Heads-up Design? - Answers It is an interface where we focus on the
screen, not on the keyboard.
What is the world space? - Answers It is the space in which drawings in autoCAD are created
and referenced to. In most CAD systems, the world space is defined using a three-dimensional
Cartesian coordinate system. Three mutually perpendicular axes, usually referred to as the X-,Y-,
and Z-axes, define this system. The intersec on of the three coordinate axes forms a point called
the origin. Any point in world space can then be defined as the distance from the origin in the X-
, Y-, and Z- direc ons. In most CAD systems, the direc ons of the arrows shown on the axes
iden fy the posi ve sides of the coordinates. The default orienta on of the Z-axis can be
considered as posi ve values in front of the monitor and nega ve values inside the monitor.
