   AutoCAD 2002 UMaT, Tka   John Annan  CAD   1 CHAPTER ONE   AUTOCAD 2002   1.1 AUTOCAD 2002 ENVIRONMENT Figure 1.1 shows a typical environment for autocad 2002. The main areas to consider are the modelspace and the command window. A lot of toolbars together with a wide variety of commands areavailable for designing in the model space.AutoCAD operates in either  Model space or Paper space . You use model space (the Model tab) to dodrafting and design work and to create two-dimensional drawings or three-dimensional models. You usepaper space (a layout tab) to create a finished layout of a drawing for plotting. When you are in a layout,you can enter mspace on the command line to make the last viewport in the layout current, and thenwork in model space in that viewport within the layout. You can switch to model space by double-clicking a viewport, and you can switch to paper space by double-clicking an area of paper space. 1.1.1 Toolbars  Toolbars contain buttons that start commands. When you move the pointing device over a toolbarbutton, the tooltip displays the name of the button. Buttons with a small black triangle in the lower-rightcorner have flyouts that contain related commands. With the cursor over the icon, hold down the pick button until the flyout appears. Release the pick button on a preferred flyout option. The Standardtoolbar at the top of the drawing area is displayed by default. This toolbar is similar to those found inMicrosoft Office programs. It contains frequently used AutoCAD commands such as DIST, PAN, andZOOM, as well as Microsoft Office standard commands such as New, Open, and Save.

To dock a toolbar 1.   Position the cursor on the name of the toolbar or in any blank area, and hold down the buttonon your pointing device.2.   Drag the toolbar to a docking location at the top, bottom, or either side of the drawing area.3.   When the outline of the toolbar appears in the docking area, release the button.To place a toolbar in a docking region without docking it, hold down CTRL as you drag. To undock a toolbar 1.   Position the cursor on the double bars at the end of the toolbar, and hold down the button onyour pointing device.2.   Drag the toolbar away from its docked location and release the button. To resize a toolbar 1.   Position the cursor on the edge of a floating toolbar until the cursor changes to a horizontalor vertical double arrow.2.   Hold down the button and move the cursor until the toolbar is in the shape you want. To close a toolbar If the toolbar is docked, undock it  Click Close button in upper-right corner of toolbar. 1.1.2 Command Window  You can display commands, system variables, options, messages, and prompts in a dockable andresizable window called the command window . To enter a command by using the keyboard, type thefull command name on the command line and press ENTER or SPACEBAR, or right-click yourpointing device. Some commands also have abbreviated names. For example, instead of entering circleto start the CIRCLE command, you can enter c. Abbreviated command names are called command aliases .If you want to repeat a command that you have just used, press ENTER or SPACEBAR, or right-click your pointing device at the Command prompt. You also can repeat a command by entering multiple, aspace, and the command name, as shown in the following example:Command: multiple circleTo cancel a command in progress, press ESC. To float the command window Click any part of the border and drag the command window away from the dockingregion until it has a thick outline. Then drop it in the drawing area of the AutoCAD window. To dock the command window Click the title bar, or an edge, and drag the command window until it is over the top orbottom docking regions of the AutoCAD window. To resize the command window when it is docked  1.   Position the cursor over the horizontal splitter bar so that the cursor appears as a doubleline and arrows.2.   Drag splitter bar vertically until command window is the size you want it to be.   AutoCAD 2002 UMaT, Tka   John Annan  CAD   3 1.1.3 Basic Operations A number of basic settings could be performed for model space. A few are discussed here.1.   Resizing of crosshairs    Tools  options  display tab  under crosshair size, adjust slider2.   Resizing of pick box    Tools  options  selection tab  under pickbox size, adjust slider3.   Displaying and disappearing of UCS icon    View  display  UCS icon  click on4.   Colouring of command window    Tools  options  display tab  click Colors command button for color options    Under window element, select command line background    Under color dialog box, select the appropriate color then click Apply & Close    Model tab background, model tab pointer, layout tabs background (paper), layout tabspointer, autotrack vector color, command line text and plot preview background could becolored through the procedure above.5.   Changing of grip size and grip color    Tools  options  selection tab  under grips, enable grips and chose appropriateselected and unselected grip color    Grip size can also be changed using the grip size slider6.   To disable today startup dialog    Tools  options  system tab  under general options, under startup:, make anappropriate selectionCommand aliases are shortcuts or alternative names for commands that you enter at the keyboard. Thisappendix lists the command aliases provided in the standard acad.pgp file. You can change or deletethese aliases, or you can add some of your own by editing the acad.pgp file.

You can enter two-dimensional coordinates as eitherCartesian (  X,Y  ) or polar coordinates. 1.2.1 Absolute Coordinate Absolute coordinate makes reference to the srcin of autocad imaginary axes. Like a graph paper, anypoint you place in the command window using absolute coordinate syntax corresponds to an x-axisvalue and y-axis value and z-axis value in the case of 3D plots. To enter an absolute coordinate (2D) At a prompt for a point, enter the coordinate using the following format: x,y    X  represents the distance and direction along the horizontal axis from the srcin (0,0). Y  represents the distance and direction along the vertical axis from the srcin (0,0).
