Why is it usual practice to plot 1:1 in paper space?
Because the purpose of paper space is to represent the drawing sheet you wish to plot to. A 1:1 representation of the drawing sheet on the screen facilitates this.

Fillet
In drafting practice, a concave curve at the corner of an object. In AutoCAD, the term fillet and the FILLET command refer to both concave and convex curves (rounds).
What is the difference between noun/verb and verb/noun editing?
In noun/verb editing you select an object first (the noun), then you execute a command to take action on the object (the verb). In verb/noun editing you specify the type of action first, and then select objects to apply it to.
What is a rectangular array? What is a polar array? What is a path array?
In rectangular arrays the pattern is one of rows and columns at regular distances apart. In polar arrays the pattern is circular, around and arc or circumference of a circle. Path arrays are created by copying objects at evenly spaced intervals along any curve, line, or closed figure.
Where are template drawings stored in a standard AutoCAD file configuration? What extension is given to template file names?

Object Snaps
Object snap tracking creates temporary construction lines, called alignment paths, from designated object snap points. Types: quadrant: A point on an object along one of the orthogonal axes, at 0°, 90°, 180°, or 270° from a given point, or the area enclosed between any two adjacent axes. tangent: A line running perpendicular to the radius of a circle and touching at only one point, or the point where the line and circle touch.

Polar array
What factors define a polar array? How many are needed to define an array?
Polar arrays are defined by the number of objects, the angle between objects, and the total angle of the array. Any two will completely define the array.

Select architectural in the Drawing Units dialog box.
How would you use the Reference option to rotate a line from 60° to 90°? How would you accomplish the same rotation without using a reference?
Select the object, enter the ROTATE command, specify the reference option, type 60 and then type 90. Without using reference, select the object, enter the ROTATE command and type 30.
What would happen if a drawing created with 18 × 12 limits were printed with a 1:1 scale on an A-size printer? What feature of the Plot Configuration dialog box would you use to find out if you weren't sure?
Since 1B is 18 x 12 and A-size paper is only 12 x 9, only part of the drawing would be printed. Use Plot Preview to see the affect before plotting.
Which of these is the least useful snap and grid setting combination?
Snap = 1.0, grid = .5
Which is likely to have the smaller setting, grid or snap? Why? What happens if the settings are reversed?
Snap will be smaller typically. A smaller snap setting makes more points accessible, while a larger grid setting keeps the screen less cluttered. If the grid is set smaller than the snap, some grid points will not be accessible.
What is the purpose of the Base Point option in the Rotate grip edit mode?
So that objects may be rotated around different points, either on or off the object.
Why do we use the Zoom XP option when zooming in floating model space viewports?
So that we can have precise information about the relationship between the size of objects in the viewport and the size of objects in paper space, this also gives us information about the elative sizes of objects shown in different viewports.

What are the advantages of using the ribbon to enter commands?
The advantage of using the ribbon is that several commands, traditionally accessed by extensive typing, multiple toolbars, or several menus, are brought together in one location in the ribbon for faster and easier access.
What linetype is always available when you start a drawing from scratch in AutoCAD? What must you do to access other linetypes?
The continuous linetype is always available. To access other linetypes you must load them from the ACAD linetype file, or another file containing linetype definitions
