  1. Introduction toAutoCAD 2007graphics screen Prepared by: Nor HelyaIman Bt. Kamaludin

  2. Starting AutoCAD 2007 1. AutoCAD 2007 is started: a) from the Windows ‘Start screen’ with a double left-click on the AutoCAD 2007 icon b) by selecting the windows taskbar sequence: Start-Programs-AutoCAD 2007 2. Both methods will briefly display the AutoCAD 2007 logo and then: either a) the actual graphics screen or b) the Startup dialogue box. 3. If the Startup dialogue box is displayed, then select Cancel at present. This will allow the user access to the graphics screen. 4. Some users may also have the Workshop and New features screens displayed during start up. If these screens are displayed, cancel them.

  3. The graphics screen

  4. 1 The AutoCAD title bar 2 The graphic screen menu bar 3 The Standard toolbar 4 The Styles toolbar 5 The Workspaces toolbar 6 The Layers toolbar 7 The Properties toolbar 8 The standard ‘windows buttons’ 9 The Windows taskbar 10 The Status bar 11 The Command prompt window area 12 The Layout tabs

  5. 13 The Co-ordinate system icon 14 The on-screen cursor 15 The Drawing area 16 Scroll bars at right and bottom of drawing area 17 The Object Snap toolbar (floating) 18 The Sheet Set Manager palette 19 The Tool Palette for ALL tools 20 The Draw toolbar (docked) 21 The Modify toolbar (docked) 22 The Pickfirst/Grips boxes

  6. Title bar The title bar is positioned at the top of the screen and displays the AutoCAD 2007 icon, the AutoCAD Release version and the current drawing name. • Menu bar The screen menu bar displays the default AutoCAD menu headings. The full menu bar headings are: File Edit View Insert Format Tools Draw Dimension Modify (Express)Window Help • The Standard toolbar The Standard toolbar is normally positioned below the screen menu bar and allows the user access to several button icon selections including New, Open, Save, Plot, etc.

  7. Workspaces, Layers, Properties and Styles toolbars These are normally positioned below and to the side of the Standard toolbar. Icon selections are: a) Workspaces: Workspace settings, My Workspace b) Layers: Layer Properties Manager, Layer Control, Make Object’s Layer Current, Layer Previous c) Properties: Color Control, Linetype Control, Lineweight Control d) Styles: Text Style Control, Dimension Style Control, Table Style Control. • The Windows buttons The Windows buttons are positioned at the right of the title bar, and are: a) left button: minimise screen b) centre button: maximise screen c) right button: close current application.

  8. The Windows taskbar This is situated at the bottom of the screen and displays: a) the Windows ‘Start button’ and icon b) the name of any application which has been opened, e.g. AutoCAD c) the time and the sound control icons d) other icons/information dependant on user requirements. • The Status bar Positioned above the Windows taskbar, the Status bar gives the user: a) on-screen cursor X, Y and Z co-ordinates information at the left b) access to the drawing aid buttons, e.g. SNAP, GRID, ORTHO, POLAR, OSNAP, OTRACK, DUCS, DYN, LWT c) access to the MODEL/PAPER space toggle.

  9. Command prompt window area 1. The command prompt area is where the user ‘communicates’ with AutoCAD 2007 to enter: a) a command, e.g. LINE, COPY, ARRAY b) co-ordinate data, e.g. 120,150; @15<30 c) a specific value, e.g. a radius of 25. 2. The command prompt area is also used by AutoCAD to supply the user with information, which could be: a) a prompt, e.g. Specify first point b) a message, e.g. object does not intersect an edge. 3. The command area can be increased in size by ‘dragging’ the bottom edge of the drawing area upwards.

  10. Layout tabs Allows the user to ‘toggle’ between model and paper space for drawing layouts. • The co-ordinate system icon 1. This is the X–Y icon at the lower left corner of the drawing area. 2. This icon gives information about the co-ordinate system in use. The default setting is the traditional Cartesian system with the origin (0,0) at the lower left corner of the drawing area. 3. The co-ordinate icon display can be altered by the user. • The cursor cross-hairs 1. Used to indicate the on-screen position, and movement of the pointing device will result in the co-ordinates in the Status bar changing. 2. The ‘size’ of the on-screen cursor can be increased or decreased to suit user preference.

  11. The drawing area 1. This is the user’s drawing sheet and can be any size required. 2. In general we will use A3-sized paper, but will also investigate very large and very small drawing paper sizes. • Scroll bars 1. Positioned at the right and bottom of the drawing area and are used to scroll the drawing area. 2. They are very useful for larger-sized drawings and can be ‘turned-off’ if they are not required.

  12. Toolbars 1. By default, AutoCAD 2007 displays the Draw and Modify toolbars docked at the left and right of the drawing screen. 2. Users may positioned them differently. • Tool palettes 1. Figure above displays the AutoCAD 2007 default palettes, these being the Sheet Set Manager and all palettes. 2. The user’s screen may not display any tool palettes. 3. Palettes can be cancelled, minimised or repositioned by the user at any time. • The Pickfirst/Grips box 1. The user may have a small square box ‘attached’ to the cursor cross-hairs. 2. This box may be the Grips and/or the Pickfirst box, both aids to the user.

  13. Terminology

  14. Menu • A menu is a list of options from which the user selects (picks) the one required for a particular task. • Picking a menu item is achieved by moving the mouse over the required item and left-clicking. • There are different types of menus, e.g. pull-down, cascade, screen, toolbar button icon.

  15. Command • A command is an AutoCAD function used to perform some task. This may be to draw a line, rotate a shape or modify an item of text. Commands can be activated by: a) selection from a menu b) selecting the appropriate icon from a toolbar button c) entering the command from the keyboard at the command line

  16. Objects • Everything drawn in AutoCAD 2007 is termed an object (or entity) e.g. lines, circles, text, dimensions, hatching, etc. are all objects. • The user ‘picks’ the appropriate object with a mouse left-click when prompted.

  17. Default setting • All AutoCAD Releases have certain values and settings which have been ‘preset’, these being essential for certain operations. Default values are displayed with <> brackets, but the actual value can be altered by the user as and when required. For example: 1. From the menu bar select Draw-Polygon and: prompt polygon Enter number of sides<4> respond press the ESC key to cancel the command. 2. Notes a) <4> is the default value for the number of sides b) polygon is the active command. 3. At the command line enter LTSCALE <R> and: prompt Enter new linetype scale factor<1.0000> (or other value) enter 0.5 <R> 4 . Notes a) <1.0000> is the LTSCALE default value on my system b) we have altered the LTSCALE value to 0.5.

  18. The escape (Esc) key • This is used to cancel any command at any time. It is very useful, especially when the user is ‘lost in a command’. • Pressing the Esc key will cancel any command and return the command prompt line.

  19. Icon • An icon is a menu item in the form of a picture contained on a button within a named toolbar.

  20. Cascade menu • A cascade menu is obtained when an item in a pull-down menu with after it’s name is selected. 1. From the menu bar select the sequence Draw-Circle and the cascade effect as right figure will be displayed. 2. Cancel the cascade effect by: a) moving the pick arrow to any part of the screen and left-clicking b) pressing the Esc key – cancels the ‘last’ cascade menu, so two escapes are required.

  21. Shortcut menu 1. A shortcut menu allows quick access to commands that are relevant to the current activity. 2. Shortcut menus are displayed with a right-click: a) within the drawing area with or without any objects selected b) within the drawing area during a command c) within the text and command windows d) within areas and on icons in Design Center e) on a toolbar, tool palette, model or layout tabs f) on the Status bar or the Status bar buttons 3. Shortcut menus typically include options to: a) repeat the last command entered b) cancel the current command c) display a list of recent user input d) cut, copy, and paste from the Clipboard e) select a different command option f) undo the last command entered. 4. Right figure displays a typical shortcut menu with a cascade effect.

  22. Dialogue boxes A dialogue box is always displayed when an item with ‘…’ after it’s name is selected: 1. Dialogue boxes allow the user to: a) alter parameter values b) toggle an aid ON/OFF c) select an option from a list. 2. Most dialogue boxes display the options On, Cancel and Help which are used as follows: OK: accept the values in the current dialogue box Cancel: cancel the dialogue box without any alterations Help: gives further information in Windows format. The Windows effect can be cancelled with File-Exit or using the Windows Close button from the title bar (the right-most button).

  23. Toolbars 1. Toolbars allow the AutoCAD 2007 commands to be displayed on the screen in button icon form. 2. There are over 30 toolbars available for selection. The toolbars normally displayed by default when AutoCAD 2007 is started are Standard, Layers, Properties, Styles, Workspaces, Modify and Draw. 3. Toolbars can be: a) displayed and positioned anywhere in the drawing area b) customised to the user preference.

  24. Tool palette 1. A tool palette is an efficient method of organising and sharing various items. 2. Tool palettes can be customised by the user. 3. By selecting Auto-hide from the title bar, the tool palette can be minimised/maximised 4. Tool palettes can be: a) cancelled by selecting the Close (topmost) button from the title bar b) activated from the menu bar with Tools-Tool Palettes Window c) positioned by the user. 5. The objects which the user can add to a tool palette include: a) Geometric objects such as lines, circles, and polylines b) Dimensions c) Blocks, Hatches, Solid fills and Gradient fills.

  25. Template • A template allows the user access to different drawing standards with different sized paper, each template having a border and title box. • AutoCAD 2007 supports several drawing standards including ANSI, DIN, Gb, ISO, JIS and Metric. • Templates will be used for our drawing work.

  26. Toggle • This is the term used when a drawing aid is turned ON/OFF and usually refers to: a) pressing a key b) activating a parameter in a dialogue box, i.e. a tick/cross signifying ON, no tick/cross signifying OFF.

  27. Function keys Several of the keyboard function keys can be used as aids while drawing, these keys being: • F1 accesses the AutoCAD 2007 Help menu • F2 flips between the graphics screen and the AutoCAD Text window • F3 toggles the object snap on/off • F4 toggles the tablet on/off (if attached) • F5 toggles the isoplane top/right/left – for isometric drawings • F6 co-ordinates on/off toggle • F7 grid on/off toggle • F8 ortho on/off toggle • F9 snap on/off toggle • F10 polar tracking on/off toggle • F11 toggles object snap tracking off • F12 the dynamic input toggle

  28. Help menu • AutoCAD 2007 has an ‘on-line’ help menu which can be activated at any time by selecting from the menu bar Help-Help or pressing the F1 function key. The Help dialogue box will be displayed as two distinct sections: a) Left: with three tab selections – Contents, Index and Search b) Right: details about the topic selected.

  29. File types • When a drawing has been completed it should be saved for future recall. • All drawings are called files. • AutoCAD 2007 supports different file formats, including: .dwg: AutoCAD drawing .dws: AutoCAD Drawing Standard .dwt: AutoCAD Template Drawing template file .dxf: AutoCAD Data Exchange Format

  30. Saved drawing names • Drawing names should be as simple as possible.

  31. Finally • At this time, we have: a) started AutoCAD b) investigated the graphics screen c) discussed some terminology. • We are now ready to draw some AutoCAD objects.
