    AutoCAD Tutorial 2:

    FOR RELEASE 2000

    PLEASE READ: ___________

    This tutorial was designed to be part of the

    introductory courses taught by the GraphicCommunications Program at NORTH

    CAROLINA STATE UNIVERSITY. All of

    the directions used in this, and the other

    tutorials in this series, assume that you are

    running AutoCAD Release 2000i on an NT

    system. These directions will only work withRelease 2000i. Other versions may not have

    the same commands or format.

    his tutorial will allow you to explore

    new features in AutoCAD while you practice

    commands you used in the previous tutorial.

    It is assumed that you completed AutoCAD

    Tutorial 1 before doing this one.

    OBJECTIVES

    After completing this tutorial, you should be

    able to:

    1. create a two-dimensional drawing using

    the CIRCLE, TRIM, and LINE

    commands;

    2. insert a drawing into the titleblock; and

    3. print a drawing to scale.

    Throughout this tutorial, you will find

    LINKS that will provide explanations

    of the commands you will need. Theseexplanations will appear in the LEFT

    PANEL of your browser window. You

    can also access information on the

    command procedures directly through

    the links in the LEFT PANEL.

    NOTES TO REMEMBER WHEN

    WORKING IN AUTOCAD

    1. When using an AutoCAD command,

    you MUST read the prompt line and

    respond as needed.

    2. In a prompt, the CAPITALIZED

    letter(s) of an option are typed short-

    cuts for that option. Information typed onthe prompt line is not case-sensitive.

    3. To exit a command and return to a

  • 8/2/2019 Auto Cad Tutoral 2

    4/53

    Command: prompt, press the Esc

    (Escape) key.

    4. In command prompts, AutoCAD's has a

    default selection. If you press the Enter

    key without typing a different option on

    the prompt line, the default option is

    selected.

    EXAMPLE: In a prompt for the Circle

    command, which reads:

    Specify center point for circle or

    [3P/2P/Ttr (tan tan radius)]:

    1.

    If no other option is selected,

    AutoCAD assumes that you will

    give it a location for the center ofthe circle. If you want to use any

    other option [2P, 3P, or Ttr], you

    must type the option on the prompt

    line.

    2. When AutoCAD asks you to indicate

    a location for an object, the default

    method of selection is a mouse pick.If you accidentally click your left

    mouse button while the cursor is in

    the drawing area, the object will be

    placed where the cursor was located

    when you clicked the mouse button.

    STEP 1

    Now that you have reviewed a few

    AutoCAD procedures, you need to open the

    classtemplate file that you used in Tutorial1. This TEMPLATE fileshould be on afloppy diskor in yourHome Directory.

  • 8/2/2019 Auto Cad Tutoral 2

    6/53

    After the file opens, use Save As... torename the file acadtutor2.

    NOTE: Click on the Model tag, next to theLayout 1 tag. If you find the titleblock onthe Model screen, use the Erase commandto remove it. You do not have to worry about

    losing the titleblock. It is in the Layout 1

    space. You may also want to open theclasstemplate file again and remove thetitleblock in Model space there and resave itto keep you from having the aggrevation of

    doing it everytime you open the file.

    STEP 2

    Before you actually begin the tutorial

    drawing, you need to practice four methods

    AutoCAD uses for locating elements in adrawing. One of these, Absolute

    Coordinates, you used in the last tutorial.

    The other three methods are Relative

    http://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/saveas2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/saveas2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.html
  • 8/2/2019 Auto Cad Tutoral 2

    7/53

    Rectangular Coordinates, Relative

    Polar Coordinates, and Object Snap

    (Osnap). Before practicing these, click onthe link forAbsolute Coordinatesto reviewthe information on this location method.

    Now, use the Line command and draw thefollowing lines with Absolute Coordinates.

    1.

    ForLine 1, draw a horizontal line 30mmlong that begins at the 0,0 point (type 0,0for the start point) and ends at 30,0 (type30,0 for the second point). Press ENTER

    to end the line. See FIGURE 1.

    NOTE: Think of Absolute Coordinatesas plotting points on a XY graph. You

    must select a X value (the first number

    in the coordinate) and a Y value (the

    number after the comma) to establish a

    location on the screen.

    2. Line 2 should be vertical, 25mm long,

    and begin at the 0,0point.

    http://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/polcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/polcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/abcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/line2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/polcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/polcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/polcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/abcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/line2.html

    3. Line 3 should also be vertical, 15mm

    long, and begin at 10,10. Remember, if

    you start your line at 10 along the X and10 along the Y, the next coordinate point

    must take this into account for the length

    of the line to be 15mm long.

    The next lines will use a combination of

    locating methods: Relative RectangularCoordinates and Object Snaps (Osnap).Object snaps are powerful AutoCAD tools

    that allow you to locate positions on existing

    elements in your drawing. When using

    Object Snaps, the cursor will change shapewhen it is over an appropriate location for

    that Osnap option. Each Osnap option willdisplay a different cursor shape.

    Before using the Osnap tools, let's place the

    Osnap toolbar on the screen. This toolbarwill allow you to select Osnaps by clicking

    on their buttons. To access this toolbar, select

    the Viewmenu and then Toolbars...

    http://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.html
  • 8/2/2019 Auto Cad Tutoral 2

    9/53

    When the Toolbars dialogue box appears,scroll down to Osnap, and click on the

    square check box to the RIGHT of itsname. After the Osnap toolbar appears onthe screen (See Figure to the RIGHT),

    select Close to exit the Toolbars dialoguebox.

    To move the Osnap toolbar to a betterlocation, hold down the LEFT mouse buttonat the top of the toolbar (by its name), and

    drag it to a convenient position. You can

    place it on the drawing screen or with the top

    and right side toolbars, on the edges of the

    AutoCAD drawing window. Buttons on thetoolbar are usually arranged horizontally, but

    will become vertical (as shown in the

    illustration to the right) if you place it with

    the toolbars on the left side of the screen.

    Slide your cursor onto one of the buttons onthe Osnap Toolbar without clicking themouse. Notice that the name of that button

    appears on the screen. You can identify any

  • 8/2/2019 Auto Cad Tutoral 2

    10/53

    button on any toolbar in this fashion.

    Relative Rectangular Coordinatesallow you to treat any point on the

    screen as if it is the 0,0,0 point. This is why

    this system is referred to as a RELATIVE

    locating method. Read the directions for the

    Osnap and Relative Rectangular

    Coordinates before drawing the linesindicated below.

    1. Line 4 should be started from the

    midpoint of the LAST line (line 3) thatyou drew earlier. After you activate the

    Line command, the prompt directs you to: Specify first point:. Use theMidpoint Osnap to select the point. AMidpoint Osnap can be activated by

    clicking on the button on the Osnaptoolbar or typing mid on the prompt line.

    Now, slide the cursor over the midpoint

    of line 3 and click the left mouse button

    http://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/osnap2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/relcoord2.html
  • 8/2/2019 Auto Cad Tutoral 2

    11/53

    when the cursor changes shape. The

    cursor change indicates that AutoCAD

    has located a midpoint. When asked forthe second point, type @10,10.

    Remember the @ symbol indicates that

    you are using a relative coordinate, and

    the second point is 10 over (along the X-

    axis) and 10 up (along the Y-axis) from

    the midpoint of line 3. See FIGURE 2.

    2. Start Line 5 from the midpoint ofline2

    and end it 25 along the X-axis and 25

    along the Y-axis from the midpoint of

    line 2. Don't forget the @ symbol before

    the coordinate or the line will not be thecorrect length.

    3. Start Line 6 at the bottomend (use the

    Endpoint Osnap) ofline number 3 (theshorter vertical line) and make it 20mm

    long and horizontal. Don't forget the @symbol.

  • 8/2/2019 Auto Cad Tutoral 2

    12/53

    Relative Polar Coordinates are

    similar to Relative RectangularCoordinates in that they use an @

    symbol and allow you to treat any

    point as if it is the0,0,0point.However, Relative Polar Coordinates

    indicate the length and the angle of the line

    instead of an X and Y position. Read theinformation on Osnaps and Relative PolarCoordinates and draw the following lines.

    1.

    Draw Line 7 so that it begins at theintersection ofLines 3 and 6 (use the

    Intersection Osnap button or type int),is 20mm long, and at a 45 degree angle.

    Type @20

  • 8/2/2019 Auto Cad Tutoral 2

    13/53

    2. Begin Line 8 from the TOP end ofLine

    2 (using the EndpointOsnap), make it

    15 mm long and at a 30 degree angle.Don't forget the @ symbol.

    3. Draw Line 9 so that it starts at the end ofLine 1 and is 15 long and at a -30 angle.

    If your lines match those in FIGURE 3,

    erase them and continue to the next part ofthe tutorial. If they don't, erase any lines that

    are wrong, and try them again. It is important

    you become comfortable with these selection

    systems.

    To check your lines, you can use an Inquirycommand called Distance.

    To activate this command, type dist at a

    Command:prompt.When the prompt asks Specify first point:,use the EndpointOsnap to select one endof a line.

    When the prompt asksSpecify second

  • 8/2/2019 Auto Cad Tutoral 2

    14/53

    point:, use the Endpoint Osnap again topick the other end of the line.

    AutoCAD will display the position, length,and angle for this line in the prompt window.

    STEP 3

    Look at FIGURE 4. This figure provides

    a view of the drawing you will construct inthis tutorial, inside of the titleblockyou

    constructed in Tutorial 1. You will complete

    this figure and then use the Insert commandto place the titleblock around it.

    You will begin by constructing a rectangle,

    which you will edit to add other features.

    **HELP NOTES

    You can type u forUndowhile you are

    inside of the Linecommand, and AutoCADwill remove the last point you placed without

    exiting the command. Many commands in

    AutoCAD will allow you to undo certain

    actions during the command.

    If you accidentally leave the Line command,you can start the next line where you left off.

    Activate the Line command and use theEndpointOsnap to select the end of the last

    line you drew.

    You may need to Zoom out further to besure that you can see all of the lines you aredrawing. Use the Realtime orAll option ofthe Zoom command to be sure you moveback far enough.

    DRAWING PROCEDURE

    For the construction of the rectangle, you will

    create a series of lines straight lines.

    NOTE: The icon that usually appearsin the lower left hand corner of your

    AutoCAD screen may not be in the same

    position as the one shown in the figures

    below. Its position, relative to the drawing,

    depends on the Zoom factor and its

    configuration. To move this icon so that it isnot in your way, we will set it so that it

    consistently stays in the lower Left Corner of

    http://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/zoom2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/zoom2.html

    17/53

    the screen. The default position for this icon

    is at the 0,0 point.

    To change the postion of the icon, typeucsicon at a Command: prompt. The nextprompt will read: Enter an option[ON/OFF/ALL/Noorigin/ORigin/Properties] : type n, forNorigin, and press

    Enter.1. First Point-Review the Linecommand

    andAbsolute Coordinates.

    Activate theLinecommand, and use anabsolute coordinate to start the first line

    at 0 on the X-axis and the 0 on the Y-axis (0,0).

    2. The second end of the line should be

    placed so that the line is 260mm long and

    horizontal. Press Enter to exit theLinecommand. See FIGURE 5.

    http://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/line2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/abcoord2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/line2.htmlhttp://www.ncsu.edu/project/graphicscourse/gc/acadtut/acadtut2000/abcoord2.html

    FIGURE 5

    **HELP NOTE: Remember, you areusing an XY coordinate orCartesian

    System to place these points. If you were

    plotting this point on graph paper, how

    far along the X-axis and the Y-axis

    would you move to place the other end

    of the line so that the line ends up130mm long and horizontal?

    At this point you probably cannot see

    all of the line you just created. Use a

    Zoomcommand to reduce the size ofthe image on the screen and then use

    the scroll bars to move it to the bottom

    of the screen.

    3. Line Two -To create the next line, first

    look at the information onRelative Polar

    Coordinates. Now,activate theLinecommand and use theEND Osnaptoselect the right end of the first line you

    added. The second end of the second line

    should be placed so that the line is

    160mm long and at a 90 degree angle.

    DO NOT EXIT THE LINECOMMAND. See FIGURE 6.

    You should have two lines that are

    perpendicular to each other, but still be in

    the Line command. If you move your

    mouse, a "rubber band-like" lineshould appear to be attached to the end of

    this line, which indicates that you are still

    in the Line command. The next line willbe attached to the "rubber band" end of

    this line.

    FIGURE 6

    4. Line Three-The next line will connect

    to the end of the last line. Look at

    FIGURE 7 to see how the drawing willlook after adding this line.If you have

    accidentally exited the Line command,reactivate it and, when the prompt asks

    for the first end of the line withSpecifyfirst point: use anOsnapto select the

    endpoint of the last line you added andpress Enter.Once this is accomplished,

    you can continue adding lines.

    Using aRelative Polar Coordinate, add

    this next pointso that the line will be260mm long and at a 180 degree angle.

    You need to consider whether you should

    use a positive or negative angle to place

    the end of this line. This will complete

    the third line. DO NOT EXIT THE

    LINE COMMAND. See FIGURE 7.

    **HELP NOTE: If you have lines in the

    wrong place, useErase to remove them

    and add them again.STEP 4

    You are now going to add two circlesto your rectangle and edit them to form arcs.

    CIRCLES can be added in several ways, butyou will add the next two circles with the

    Tangent Tangent Radius (Ttr) option. Readthe information on constructing Circles withthe Ttroption. Look at FIGURE 9 to seewhere to place these circles. The elements the

    circles will touch should be clear.

    Now, add a 80mm radius circle (on the right

    side of the figure) using the Ttroption. Usethe same option to add a 40mm radius

    circle (on the upper left side of the figure). If

    your figure does not match the one inFIGURE 9, useUndo orErase toremove them and try placing them again.

    STEP 5You now need to trim the rectangle back

    to the circles, remove one line, and trim the

    circles so that you are left with arcs. You will

    trim the lines in STEP 5 and the circles in

    STEP 6. Read the information on the Trimcommand.

    Now, trim the lines touching the large circle.Examine FIGURE 10 to see how the

    drawing should look when you complete this

    first trim stage.

    FIGURE 14

    AutoCAD allows you to construct regular

    polygons; however, a polygon created in this

    program is a single orgrouped object and is

    oriented to a default angle. This means that

    you must Rotate the polygonto change itsorientation and Explode it before you canedit it. You will be doing both of these in this

    step.

    Read the information on thePolygoncommandand Center Osnap(if needed).

    Next, add a Hexagon that is concentric with

    the larger arc and has a radius of30mm

    across its flats. Remember, if it is constructed

    to a measurement across its flats, it iscircumscribed.

    With the hexagon in the drawing, click on

    one of its lines with the Left mouse button.

    Notice that the whole polygon selects. This is

    because it is a grouped item. You cannotselect just one line. Use the Escape Key to

    deselect the Polygon when you are done. In a

    later tutorial you will encounter a discussion

    of(Plines). Polygons are created asPolylines, which are treated by AutoCAD as

    a single object.Polylines

    The hexagon you just added has a corner at 0

    degrees on the XY plane. This is a

    hexagon's default orientation in AutoCAD.

    You need to rotate the hexagon so that this

    corner is at a 90 degree angle (aligned with

    the Y-axis). Read the information on the

  • 8/2/2019 Auto Cad Tutoral 2

    a basepoint for rotation, use the CenterOsnapand select the large arc. SeeFIGURE 15.

    like a circle. If this hexagon had not been

    concentric with the large arc, you would have

    had to find some way to create a basepointfor its rotation. Fortunately, a basepoint does

    not have to be part of the object being

    rotated. Other items can be used for this

    reference. For Polygons with an even number

    of sides, you can add a line that connects two

    corners of the Polygon and crosses throughits center. The midpoint of this construction

    line could be used as the basepoint for

    rotating the Polygon. Elements are added to a

    CAD drawing for construction purposes the

    same way they are to instrument drawings.

    To edit the hexagon, Explodeit intoindividual lines so it is no longer a single or

    grouped entity. It is not possible to remove

    part of it otherwise.

    **HELP NOTE: You have twoboundary

    edges, and both can be selected at the same

    time. One is the top horizontal line, and theother is the large arc. Since they are

    individual elements in the drawing, they both

    have to be selected. Once the boundary edges

    are selected, you click on the TOP ends of

    both of the polygon's vertical lines to extend

    them to the boundary edges.

    AutoCAD in this command, and several

    other commands, is directional. If you

    click on the lower end of these lines, the

    Now that the visible lines of the drawing

    are complete, you need to add center lines.

    Examine FIGURE 21, which again showsyou a scaled down version of the completed

    drawing inside a titleblock.

    FIGURE 21

    So far all of the construction of this drawing

    has been on one layer of the file. You will

    add the center lines in the Center layer.

    The startpage file, which you used inTutorial 1, was already been configured with

    a set of layers.Since you used this file to

    create the classtemplate file you used for this

  • 8/2/2019 Auto Cad Tutoral 2

    37/53

    tutorial, it also has the same layers.If you

    open a new AutoCAD file, only the 0 layer

    (the default layer in AutoCAD) exists.Another configuration that was made to the

    startpage filewas the assignment of line

    types, line colors, and line weights to the

    layers. AutoCAD refers to this as assignment

    BYLAYER. Anything drawn in a layer will

    be in the line type, line color, and lineweight (when printed) assigned to that

    layer.

    To draw center lines in thisfile,all you

    have to do is change to the Center Layer. In

    a later tutorial, you will be shown how to add

    layers to a new drawing file and configure

    them. If you have accidentally started this

    tutorial in a default AutoCAD file, there will

    be no Center layer.

    Look at the Layer Status Window in the

    upper left corner of the screen,which

    indicates the current layer (see FIGURE 22).

    38/53

    1. FIGURE 22

    Look at the symbols in the Layer Status

    Window to the Left of the layer name.These symbols indicate the following

    (from Left to Right):

    2. The layer is VISIBLE or is ON. This is

    indicated by the yellow light bulb.Clicking on the light bulb toggles the

    layer between visible and invisible. Items

    on an invisible layer are still printed.

    3. The layer is THAWED. The yellow sun

    indicates the layer is thawed, can be

    edited, and can be printed. When a layer

    is frozen, a snowflake indicates it is

    invisible, cannot be edited, and cannot be

    printed.

    4. The layer is UNLOCKED. The open

    lockindicates the layer is unlocked, can

  • 8/2/2019 Auto Cad Tutoral 2

    be edited, and can be printed. A closed

    lockindicates the layer cannot be edited,

    but it is visible, and can be printed.

    5. The layer's line COLORis white. The

    layer's color is always indicated in thesmall square between the lock and the

    layer name.

    6. The NAME of the layer is zero (0). Each

    layer must be given a unique name to

    differentiate it from the others.

    drawing you created into that file now. To do

    this, you will use the Insert command youused in the last tutorial.

    item that you moved to a different layer, and

    its layer will appear in the Layer Status

    Window.

    To add center lines to the arcs in your

    drawing, first you will addtwo circles.The

    circles radii should be 10mm larger than the

    arcsin the final printout of the drawing, so

    that you can construct center lines that

    extend 20mm beyond the arcs. You must

  • 8/2/2019 Auto Cad Tutoral 2

    43/53

    double the size of the circles because you

    will scale it half size in the titleblock for

    printing. You will have to print the drawinghalf size for it to fit. Therefore, if the center

    lines are twice as long in your drawing, they

    will be the right size in the printout.

    To add these circles, use theCircle

    command's default option and identify theircenters with the Center Osnapso they areconcentric with the large and small arcs.

    You may need to read the information on

    Circleand Osnap Centerto see how to

    place these.

    The circle that is concentric with the large

    arc should have a radius of 100mm,

    and the circle that is concentric with the

    small arc should have a radius of 60mm.

    Remember, when you use the Center

    Osnap, you must click on the edge of thearcs to identify them.

    VIEWPORT in the Paper of the Paper Spaceso the drawing will show through from

    Model Space.

    The command you will use to create this

    methods of accessing this command.To use the Viewportstoolbar, you mustfirst place the toolbar on the AutoCAD

    screen. This toolbar can be displayed on the

    a scale factor on the Viewportstoolbar oruse Zoom XP.

    To change the size of the drawing in the

    viewport with either method, you must firstselect the viewport edge. Since we made it

    the same size as the drawing area in the

    titleblock, if you click on the top line of the
