      Center, Diameter:

      1. Specify the center (P1) location.

      2. Specify the Diameter (P2). (Define the Diameter by moving the cursor or typing Diameter)

      2 Points:

      1. Select the 2 point option

      2. Specify the 2 points (P1 and P2) that will determine the Diameter.

      3 Points:

      1. Select the 3 Point option

      2. Specify the 3 points (P1, P2 and P3) on the circumference.

      The Circle will pass through all three point

      Tangent, Tangent, Radius:

      1. Select the Tangent, Tangent, Radius option .

      2. Select two objects (P1 and P2) for the Circle to be tangent to by placing the cursor on the object and pressing the left mouse button

      3. Specify the radius.

      Tangent, Tangent, Tangent:

      1. Select the Tangent, Tangent, Tangent option

      2. Specify three objects (P1, P2 and P3) for the Circle to be tangent to by placing the cursor on each of the objects and pressing the left mouse button.

      (AutoCAD will calculate the diameter.)

RECTANGLE

      A Rectangle is a closed rectangular shape. It is one object not 4 lines.

      You can specify the length, width, area, and rotation options.

      You can also control the type of corners on the rectangle—fillet, chamfer, or square and the width of the Line.

       First, let’s start with a simple Rectangle using the cursor to select the corners.

      1. Start the RECTANGLE command by using one of the following:

      Ribbon = Home tab / Draw panel /

       or

       Keyboard = REC <enter>

      2. The following will appear on the command line:

       Command: _RECTANG

       Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]:

      3. Specify the location of the first corner by moving the cursor to a location (P1) and then press the left mouse button.

      The following will appear on the command line:

       Specify other corner point or [Area / Dimensions / Rotation]:

      4. Specify the location of the diagonal corner (P2) by moving the cursor diagonally away from the first corner (P1) and pressing the left mouse button.

       OR

      4. Type D <enter> (or click on the blue letter “D”)

      Specify length for rectangles <0.000>: Type the desired length <enter>.

      Specify width for rectangles <0.000>: Type the desired width <enter>.

      Specify other corner point or [Dimension]: move the cursor up, down, right or left to specify where you want the second corner relative to the first corner and then press <enter> or press left mouse button.

       OPTIONS: Chamfer, Fillet and Width

      Note: the following options are only available before you place the first corner of the Rectangle.

      Note: Sizes shown in brackets [...] are for metric users. Enter the numbers without the brackets. Example: [12.7] just enter 12.7

       CHAMFER

      A chamfer is an angled corner. The Chamfer option automatically draws all 4 corners with chamfers simultaneously and all the same size. You must specify the distance for each side of the corner as distance 1 and distance 2.

      Example: A Rectangle with distl = .50” [12.7 mm] and dist2 = .25” [6.35 mm]

      1. Select the Rectangle command

      2. Type C <enter> (or click on the blue letter “C”)

      3. Enter .50 [12.7] for the first distance

      4. Enter .25 [6.35] for the second distance

      5. Place the first corner (P1)

      6. Place the diagonal corner (P2)

       FILLET

      A fillet is a rounded corner. The fillet option automatically draws all 4 corners with fillets (all the same size). You must specify the radius for the rounded corners.

      Example: A Rectangle with .50” [12.7 mm] radius corners. *-

      1. Select the Rectangle command

      2. Type F <enter>( or click on the blue letter “F”)

      3. Enter .50 [12.7] for the radius.

      4. Place the first corner (P1)

      5. Place the diagonal corner (P2)

       Note: You must set Chamfer and Fillet back to “0” before defining the width. Unless you want fat lines and Chamfered or Filleted corners.

       WIDTH

      Defines the width of the rectangle lines.

      Note: Do not confuse this with the “Dimensions” Length and Width.

      Width makes the lines appear fatter. .

      Example: A Rectangle with a width of .50” [12.7 mm]

      1. Select the Rectangle command Width-

      2. Type W <enter> (or click on the blue letter “W’)

      3. Enter .50 [12.7] for the width.

      4. Place the first corner (P1)

      5. Place the diagonal corner (P2)

OPTIONS: Area and Rotation
