The cursor should snap to the end of the line like a magnet. A little square and a tooltip are displayed.

      14. Press the left mouse button to attach the new line to the endpoint of the previously drawn vertical line.

      15. Stop the Line command and disconnect by pressing <enter>.

Running Object Snap

      Selecting Object Snap is not difficult but AutoCAD has provided you with an additional method to increase your efficiency by allowing you to preset frequently used Object Snap options. This method is called Running Object Snap.

      When Running Object Snap is active the cursor will automatically snap to any preset Object Snap locations thus eliminating the necessity of invoking the Object Snap Menu for each locations.

      First you must set the running Object Snaps, and second, you must turn on the Running Object Snap option.

       Setting Running Object Snap

      1. Select the Running Object Snap dialog box using one of the following:

       Keyboard = DS <enter<

       or

       Status Bar = Left Click on Object Snap button down arrow and select Object Snap Settings.

      2. Select the Object Snap tab.

      3. Select the Object Snaps desired.

      (In the example below Object Snap Endpoint, Midpoint and Intersection have been selected.

      4. Select the OK button.

      5. Turn on the Object Snap button on the Status Bar. (Blue is on)

      6. Now try drawing the line from the endpoint to the midpoint again but this time do not select the “Object Snap Menu”. Just move the cursor close to the endpoint and the cursor will automatically snap to the end of the line.

      7. Move the cursor to approximately the middle of the right hand vertical line and the cursor will automatically snap to the midpoint of the line.

      8. Move the cursor close to the lower endpoint of the left hand vertical line and the cursor will automatically snap to the lower endpoint of the left line.

       Running Object Snap is very handy but remember do not select more than 3 or 4 at a time. The selections will fight each other and you may end up snapping to a location that you did not want.

       If you wish to snap to a location that is not preset merely select the Object Snap Menu, as shown on page 4-2, and select the one you want. Running Object Snap and Object Snap work together very well but it may take a little practice.

Zoom

      The Zoom command is used to move closer to or farther away from an object. This is called Zooming In and Out.

      The Zoom commands are located on the Navigate panel of the View tab and are off by default. Select the View tab then right-click on any panel and select Show Panels, activate the Navigate panel. (To show panels refer to page 1-11.)

      1. Select the Zoom command by using the following:

       Ribbon = View Tab / Navigate Panel

      2. Select the down arrow to display all of the selections.

      You may also select the Zoom commands using one of the following:

      Right click and select Zoom from the Shortcut Menu. (Refer to Intro-5 for “right-click” settings.)

      Keyboard = Z <enter>. Select from the options listed..

       How to use Zoom / Window

      1. Select Zoom / Window (Refer to previous page).

      2. Create a window around the objects you want to enlarge. (Creating a “window” is a similar process to drawing a rectangle. It requires a first corner and then diagonal corner.)

       How to return to Original View

      1. Type: Z <enter> A <enter> (This is a shortcut
