Saveas ; Save As

Which one of the following is NOT a way to draw a circle by giving this data to AutoCAD?

center point after typing "Cr" in the command line

Where is 0 degrees located in AutoCAD's default units setup?

horizontally to the right on the screen

The grid is only a visual reference. It has __________ on selection of points. Snap is invisible, but it __________ point selection. Grid and snap may or may not have the same setting.

no effect - dramatically affects

Where is 270 degrees located in AutoCAD's default units setup?

vertically straight down

If a line's starting point coordinates are (0,1) and ending point coordinates are (0,5), what is the length of this line?

4

__________________ are standard ordered triplets giving (x,y,z) coordinates relative to the screen grid which ordinarily has its origin in the lower left hand corner. X values are measured across the screen from left to right. Y values are measured from the bottom of the screen up. Z values are off the screen

Absolute coordinates

What key do you use to cancel a command?

Esc

If you want to draw a line in Autocad, what would you type in the command window?

L

____________ is an alternative to windowing that is useful in many cases where a standard window selection could not be performed. The selection procedure is the same with "Selection by Window" method, but a crossing box opens to the left instead of to the right and all objects that cross the box will be chosen, not just those that lie completely inside the box

Selection by Crossing Window

_____________ is an important concept in AutoCAD and CAD in general. There are several AutoCAD features through which an approximate screen cursor location will lock onto a precise numerical point, a point on an object, or the extension of an object. This means that the operator does not have to hunt or visually guess at precise point locations. The simplest form of it is called incremental snap or grid snap, because it is conceptually related to the screen grid

Snap

____________ is more than a convenience. In many cases it is a necessity. With "it" off it is virtually impossible to locate any point precisely. If you try to locate the point (6.5000,6.5000,0.0000) with "it" off, for example, you may get close, but the probability is very small that you will actually be able to select that exact point.

Snap 6.5

Where is -45 degrees located in AutoCAD's default units setup?

at a 45 degree angle below the horizontal.

The coordinate display keeps track of coordinates as you move the pointer.These coordinates are standard coordinate values in a three dimensional coordinate system originating from (0,0,0). The first value is the x value, showing the horizontal position of the cross hairs, measuring left to right across the screen. The second value is y, or the vertical position of the cross hairs, measured from bottom to top on the screen. Points also have a z value, but it will always be 0 in two-dimensional drawing and can be ignored until you begin to draw in 3D.Where is the "coordinate display" located on the screen?

at the bottom of the status line

While you are drawing a line, prompt in command window allows you to stay in the LINE command to draw a whole series of connected lines if you wish. You can draw a single line from point to point, or a series of lines from point to point to point to point. In either case, you must tell AutoCAD when you are finished by pressing _____________ or _______________.

enter - the space bar

Which one of the following is NOT a way to draw a circle by giving this data to AutoCAD?

three points on the circle's circumference and three tangent points

You have just entered the point (1,1,0) and you now wish to enter the point two units straight up from this point. How would you identify this point using polar coordinates?

2<90,0

You want to draw a circle, two end points for this circle are (6,5) and (6,7). In the command line you have: "Specify center point for circle or [3P/2P/Ttr (tan tan radius)]/:" Which one of the following would you type in the command window at this instant?

2P

You want to draw a circle, you do not know the radius, but you do know two points, (6,5) and (6,7), on this circle's circumference. In the command line you have: "Specify center point for circle or [3P/2P/Ttr (tan tan radius)]/:" Which one of the following would you type in the command window at this instant?

2P

If a line's starting point coordinates are (2,1) and ending point coordinates are (2,4), what is the length of this line?

3

You are drawing a circle with radius 3 and center at the point (6, 5). In the command line you have:"Specify radius of circle or [Diameter):"Which one of the following would you type in the command window at this instant?

3

From which direction does AutoCAD start measuring angles?

3 o'clock

You want to draw a circle. This circle will pass through the points (2.25,4.25), (3.25,5.25),and (4.25, 4.25). In the command line you have: "Specify center point for circle or [3P/2P/Ttr (tan tan radius)]/:" Which one of the following would you type in the command window at this instant?

3P

You want to draw a circle with radius 3 and center at the point (6, 5). In the command line you have: "Specify center point for circle or [3P/2P/Ttr (tan tan radius)]/:" Which one of the following would you type in the command window at this instant?

6,5

You have just entered the point (1,1,0) and you now wish to enter the point two units straight up from this point. How would you identify this point using relative coordinates?

@0,2,0

__________ coordinates also use x, y, and z values but these are measured from the last point entered, rather than from the screen origin. The @ sign represents the last point entered, so that "@3,4,0" indicates the point over three, up four, with no change in the z direction from the last point entered

Relative

_______________ extends from the start point to the cross hairs on the screen. If you move the cursor, you will see that this visual aid stretches, shrinks, or rotates like a tether, keeping you connected to the start point.

Rubber band

Which of the following is NOT a way to enter the LINE command?

Type "L" at the command window and press F2

Which one of the following is NOT a way to enter the CIRCLE command?

Type Cr at the command prompt

_____ undoes the last command, so if you have done anything else since drawing the line, you will need to type "U" more than once. In this way you can walk backward through your drawing session, undoing your commands one by one

U

For drawing an enclosed figure like a square or rectangle, the LINE command provides a convenient "CLOSE" option. "CLOSE" will connect the last in a continuous series of lines back to the starting point of the series. In drawing a square, for instance, you would simply type _______ and then press in lieu of drawing the last of the four lines. For this to work, the whole square must be drawn without leaving the LINE command.

C

What does CAD, in the word of AutoCAD, stand for?

Computer-Aided Design

You are drawing a circle with diameter 3 and center at the point (6, 5). In the command line you have:"Specify radius of circle or [Diameter):"Which one of the following would you type in the command window at this instant?

D

Another convenient drawing method is called __________________. In this method, you pick the first point and then show the direction of the line segment you wish to draw; but instead of picking the other endpoint you type in a value for the length of the line

Direct Distance Entry

You can repeat a "last command" by pressing ______________.

Enter or the space bar

Many of the most often used commands, such as ARC, ERASE, and FILLET, have "aliases." These one- or two-letter abbreviations are very handy. In the command line typing "E" and then pressing enter is used for ______________.

Erasing an object

What function key opens and closes the text window?

F2

The _____________ is simply a matrix of dots that helps you find your way around on the screen. It will not appear on your drawing when it is plotted, and it may be turned on and off at will. You may also change the spacing between dots using this command

Grid

Polar coordinates are in a length, angle, z format and are given relative to the last point you picked. They look something like this: 5.6569 45, 0.0000. There are three values here: 5.6569, 45, and 0.0000. The first number (5.6569) is the _________ from the starting point of the line to the cross hairs. The second (45) is an (a) _________ of rotation, measuring counterclockwise, with 0 degrees being straight out to the right. The third value (0.0000) is the z coordinate, which will remain zero in 2D drawing.

distance - angle
