       Method 2. Keyboard entry

      You may type commands on the Command Line (Shown below) or in the Dynamic Input Tooltip (Shown on the next page).

      It depends on whether you have Dynamic Input on or off.

       Command Line

       How to enter a command on the Command Line.

      1. Place the cursor in the Command Line area. (Important.)

      2. Type the first letter of a command, such as c for circle.

img

      3. A list of commands that begin with the letter c will appear. Select the command from the list.

      4. When you enter a command such as Circle the prompt and options will be displayed on the Command Line.

img

      5. The prompt for Circle command asks you to:

       “Specify center point for circle" or [ 3P/2P/Ttr (tan tan radius) ]:

      The information within the [ ] brackets are options that you may select.

       Dynamic Input

      Dynamic Input is another method of inputting commands, values and select options.

      To use Dynamic Input you must turn on the Dynamic Input button in the Status Bar, shown on page 1-14.

img

      If you choose to use Dynamic Input, the command will be entered in the tooltip box beside the cursor.

       How to enter a command using Dynamic Input.

      1. Place the cursor in the Drawing Area. (Important)

      2. Type the first letter of a command, such as c for circle.

      3. A list of commands that begin with the letter c will appear. Select the command from the list.

      4. If you press the img down arrow, the options will appear below the prompt.

img

      Notice the command entry and prompts are being displayed on the Command Line also.

      Using the Command Line or Dynamic Input is your choice.

      A Line can be one segment or a series of connected segments.

      But each segment is an individual object.

img

      Start the Line command using one of the following methods:

      Ribbon = Home Tab / Draw Panel / img

       or

      Keyboard = L <Enter>

       Lines are drawn by specifying the locations for each endpoint.

      Move the cursor to the location of the “first” endpoint (1) then press the left mouse button and release. (Click and release, do Click and Drag) Move the cursor again to the “next” endpoint (2) and press the left mouse button. Continue locating “next” endpoints until you want to stop drawing lines.

      There are 2 ways to Stop drawing a line: press the <Enter> key or press the <Spacebar>

img
img To quickly repeat the Line command, press the <Spacebar>.

       Horizontal and Vertical Lines

      To draw a Line perfectly Horizontal or Vertical select the Ortho mode by selecting the Ortho button on the Status Bar or pressing the <F8> key.

img

       Try the following example:

      1. Select the Line command. (Refer to the previous page.)

      2. Place the First endpoint anywhere in the drawing area.

      3. Turn Ortho on by selecting the Ortho button or <F8>. (The “Ortho” button will change to a neon blue when on.)

      4. Move the cursor to the right and press the left mouse button to place the next endpoint. (The line should appear perfectly horizontal.)

      5. Move the cursor down and press the left mouse button to place the next endpoint. (The line should appear perfectly vertical)

      6. Now turn Ortho off by selecting the Ortho button. (The “Ortho” button will change to gray when off.)

      7. Now move the cursor up and to the right on an angle (the line should move freely now) and press the left mouse button to place the next endpoint.

img
img Ortho can be turned on or off at any time while you are drawing. It can also be turned on or off temporarily by holding down the <Shift> key.
