using a Crossing Window.

      eRase You may erase an object instead of trimming while in the Trim command.

      Undo You may “undo” the last trimmed object while in the Trim command

UNDO and REDO

      The UNDO and REDO tools allow you to undo or redo previous commands. For example, if you erase an object by mistake, you can UNDO the previous “erase” command and the object will reappear. So don’t panic if you do something wrong. Just use the UNDO command to remove the previous commands.

      The Undo and Redo tools are located in the Quick Access Toolbar.

       Note:

      You may UNDO commands used during a work session until you close the drawing.

      How to use the Undo tool.

      1. Draw a line, circle and a rectangle.

       Your drawing should look approximately like this.

      2. Next Erase the Circle and the Rectangle.

       (The Circle and the Rectangle disappear.)

      3. Select the UNDO arrow.

      You have now deleted the ERASE command operation. As a result the erased objects reappear.

      How to use the Redo command:

      Select the REDO arrow and the Circle and Rectangle will disappear again.

WIPEOUT

      The Wipeout command creates a blank area that covers existing objects. The area has a background that matches the background of the drawing area. This area is bounded by the wipeout frame, which you can turn on or off.

      1. Select the Wipeout command using one of the following:

Ribbon = Home tab / Draw Panel / orKeyboard = Wipeout <enter>

      2. Command: _wipeout Specify first point or [Frames/Polyline] <Polyline>: specify the first point of the shape (P1)

      3. Specify next point: specify the next point (P2)

      4. Specify next point or [Undo]: specify the next point (P3)

      5. Specify next point or [Undo]: specify the next point or <enter> to stop

       TURNING FRAMES ON OR OFF

      1. Select the Wipeout command.

      2. Select the “Frames” option.

      3. Enter ON or OFF.

      Note: If you want to move the objects and the wipeout area, you must select both and move them at the same time. Do not move them separately.

ZOOM

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

      1. Select the Zoom command by using the following:

       Ribbon = View tab / Navigate 2D 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 Short cut menu.

      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 a diagonal corner)

      Note: the objects have been magnified. But the actual size has not changed.

       How to return to Original View

      1. Type: Z <enter> A <enter> (This is a shortcut for Zoom / All)

      Or you can select the “All” tool from the panel shown on the previous page.

MODEL and LAYOUT OPTIONS

       Very important:

       Before I discuss Model and Layout I need you to confirm Model and Layout tabs are displayed.

      This will just take a minute.

      1. Type: options <enter>

      2. Select the Display tab.

      3. Check and un-check boxes as shown.

      4. Select the OK button

      5. The lower left corner of the drawing area should display the 3 tabs, Model, Layout1 and Layout2 and a few tools should be displayed in the lower right corner above the command line.
