  2. Material to Cover • Selecting AutoCAD Commands • Function Keys • Drawing with keyboard coordinates • LINE command • ID command • OSNAP settings • LIMITS • UNITS • SNAP • GRID and ORTHO Function Keys, Grid, Snap, Limits

  3. Selecting AutoCAD Commands Function Keys, Grid, Snap, Limits

  4. Selecting AutoCAD Commands • Commands may be selected in four ways • 1. Executed by picking a toolbar button or icon • 2. Selected from one of the pull-down menus • 3. Selected from the digitizer table menu overlay • 4. Typed at the keyboard Function Keys, Grid, Snap, Limits

  5. Selecting AutoCAD Commands • Command Line Editing • You can select previously used commands in the current drawing session by using the up and downarrowkeys • Just hit the “up” arrow to recall the command. • This capability allows for fast, repeated use of the same command. Function Keys, Grid, Snap, Limits

  6. Keys Function Keys, Grid, Snap, Limits

  7. The [Enter] key and the [Spacebar] Function Keys, Grid, Snap, Limits

  8. The [Enter] key and the [Spacebar] • The [Spacebar] functions (most of the time) like the [Enter] key. • A good AutoCAD speed tip is to • Keep your right hand on the mouse. • Keep your left hand on the keyboard and use it to enter data. • use your left thumb as the [Enter] key. Function Keys, Grid, Snap, Limits

  9. Keys • The [Esc] key • Control Keys • Function Keys Function Keys, Grid, Snap, Limits

  10. Keys • The [Esc] key • Cancels a command and returns to the Command: prompt Function Keys, Grid, Snap, Limits

  11. Keys • Control Keys • Control functions are activated by pressing and holding the [Ctrl] key while pressing a second key. Function Keys, Grid, Snap, Limits

  12. Keys • Ctrl B - Snap mode (toggle) • Ctrl C - Copy • Ctrl D - coordinate display on/off toggle • Ctrl E - crosshairs in isoplane toggle (left/right/top) • Ctrl G - Grid on/off toggle • Ctrl H - same as backspace • Ctrl L - Ortho mode toggle • Ctrl O - Open Function Keys, Grid, Snap, Limits

  13. Keys • Ctrl P - Print (Plot) • Ctrl R - toggle viewport • Ctrl S - Save • Ctrl T - Tablet mode toggle • Ctrl V - Paste • Ctrl X - Cut • Ctrl Y - Redo • Ctrl Z - Undo Function Keys, Grid, Snap, Limits

  14. AutoCAD Units • The UNITS command • Allow you to set the unit used by AutoCAD. • Choices are: • Decimal decimal units • Fractional fractional units • Engineering decimal feet • Architectural feet and inches • Scientific 1 x 10x Function Keys, Grid, Snap, Limits

  15. AutoCAD Units • For this class, we will use either • Decimal decimal units • Architectural feet and inches Function Keys, Grid, Snap, Limits

  16. Drawing Aids Function Keys, Grid, Snap, Limits

  17. Drawing Aids • AutoCAD provides drawing aids that help prepare the drawing layout, increase speed and efficiency and ensure accuracy. • These drawing aids are: • GRID • SNAP • ORTHO Function Keys, Grid, Snap, Limits

  18. The GRID Function Keys, Grid, Snap, Limits

  19. The GRID • A grid • is a predefined spacing of points which is used to help lay out a drawing • The GRID command places this pattern of dots/lines at any desired spacing. • It can be equal or non-equal spacing • The grid pattern shows only within the drawing limits • Entering the GRID command provides a prompt showing the default grid spacing and several other options. Function Keys, Grid, Snap, Limits

  20. The GRID Command Function Keys, Grid, Snap, Limits

  21. The GRID • GRID • Is a COMMAND and a TOGGLE • Command • Displays a grid pattern in the current viewport. • Toggle • Turns the display of the grid pattern in the current viewport ON or OFF. Function Keys, Grid, Snap, Limits

  22. Grid Settings Right-click GRID button Function Keys, Grid, Snap, Limits

  23. Function Keys, Grid, Snap, Limits

  24. GRID Command • GRID can also be set by using the Command: prompt. • More tedious to use than right-clicking GRID on Status Bar. • Command:GRID • Grid spacing (X) or ON/OFF/Snap/Aspect <0.5…): 0.25 Function Keys, Grid, Snap, Limits

  25. GRID Command • GRID on or off: • Click the GRID button on the Status Bar • or • The [F7] function key • or • [Ctrl + [G] Function Keys, Grid, Snap, Limits

  26. GRID Command – Aspect Option • Aspect Option • Setting a different horizontal/vertical grid spacing can be done. • Type a different X, Y value. • From the Command: prompt • Select the Aspect option of the GRID command. Function Keys, Grid, Snap, Limits

  27. Function Keys, Grid, Snap, Limits

  28. GRID Command – Aspect Option • Command: GRID • Grid spacing (X) or ON/OFF/Snap/Aspect<current>: A • Horizontal spacing (X) <0.5000>:1 • Vertical spacing (Y) <0.5000>: .5 Function Keys, Grid, Snap, Limits

  29. The SNAP Command Function Keys, Grid, Snap, Limits

  30. The SNAP • SNAP • Is a COMMAND and a TOGGLE • Command • Restricts cursor movement to specified intervals • Similar to an invisible screen grid. • Toggle • Turns the SNAP action ON or OFF. Function Keys, Grid, Snap, Limits

  31. SNAP • The cursor crosshairs move freely on the screen • It may be difficult to accurately place a point • It would be desirable to cause the cursor to move only to an invisible grid. • This is called “SNAP”. • Very useful • Makes drawing much easier and more accurate Function Keys, Grid, Snap, Limits

  32. SNAP • Snap grid or snap resolution • controls the movement of the cross-hairs to this invisible grid. • It can be set to a different value than the GRID command. • The two commands SNAP and GRID are generally used together. Function Keys, Grid, Snap, Limits

  33. The SNAP Command Function Keys, Grid, Snap, Limits

  34. The SNAP Command • Properly setting the Snap Grid can greatly increase your drawing speed. • The SNAP command is used to set the invisible snap grid. SNAP Settings Right-click SNAP button Function Keys, Grid, Snap, Limits

  35. Function Keys, Grid, Snap, Limits

  36. The SNAP Command • Setting SNAP can also be done at the Command: prompt • Command: SNAP • Snap spacing or ON/OFF/Aspect/Rotate/Style <current> • Pressing [Enter] • accepts the value shown in brackets. • If a different spacing is required, such as 0.25, enter the new value. Function Keys, Grid, Snap, Limits

  37. The SNAP Command • Command: SNAP • Snap spacing or ON/OFF/Aspect/Rotate/Style <current>: 0.25 • This sets up snap at 0.25 Function Keys, Grid, Snap, Limits

  38. Rotating the SNAP Grid Function Keys, Grid, Snap, Limits

  39. Rotating the SNAP Grid • The normal snap grid is horizontal rows and vertical columns. • The grid can be rotated using the Rotate option of the SNAP command to a different angle. Command: SNAP Snap spacing or ON/OFF/Aspect/Rotate/Style <current>: R Basepoint <0.0000,0.000>:(press [Enter], type a new coordinate value, or pick a new base point. Rotation angle <0>: 25 Function Keys, Grid, Snap, Limits

  40. Function Keys, Grid, Snap, Limits

  41. Setting the SNAP Style • The Styleoption of the SNAP command allows you to set the snap grid to either a • Standard (default) or • Isometric pattern. • Command: SNAP • Snap spacing or ON/OFF/Aspect/Rotate/Style <current>: S • Standard/Isometric <current> S Function Keys, Grid, Snap, Limits

  42. Function Keys, Grid, Snap, Limits

  43. Setting Grid Spacing Relative To SNAP Spacing • The visible grid can be set to be the same as the invisible snap grid. • Choose the Snap option of the GRID command. Function Keys, Grid, Snap, Limits

  44. Setting Grid Spacing Relative To SNAP Spacing • Command: GRID • Grid spacing or ON/OFF/Aspect <current>: 2x • In this case the GRID spacing would be 2x the SNAP setting. Function Keys, Grid, Snap, Limits

  45. Limits Function Keys, Grid, Snap, Limits

  46. The AutoCAD Drawing Area • The AutoCAD drawing area is basically INFINITE in all directions. • Think “outer space” • It is beneficial to “define a drawing area” that represents the size of your project. • LIMITS are the extent of the drawing area. Function Keys, Grid, Snap, Limits

  47. The AutoCAD Drawing Area • LIMITS allow you to define a reasonable drawing area. • This area can be turned • On • Off • You can draw outside the area when LIMITS is turned off. Function Keys, Grid, Snap, Limits

  48. The AutoCAD Drawing Area • LIMITS • Should correspond to the project maximum size. • For example: a building being drawn in AutoCAD should fit within the drawing limits. • If the Technology building was drawn in AutoCAD, the limits would be at least 300 feet by 50 feet (!) Function Keys, Grid, Snap, Limits

  49. The AutoCAD Drawing Area • LIMITS • The sheet size on which the project will be plotted must also be considered when determining LIMITS. • For most assignments in the class, we will use a sheet size of 11” x 8.5”. • Set your limits to this value. Function Keys, Grid, Snap, Limits

  50. Limits • If you wanted a 17” x 11” drawing area, you would set the LIMITS to 17, 11. • The first number is the horizontal dimension. • The second number is the vertical dimension. Function Keys, Grid, Snap, Limits
