Parametric tab, Geometric, Dimensional










 Parametric tab: In this tab we parametric drawing tools, allowing adding constraints to the two-dimensional geometry drawing entities, controlling Thus the positional relationship between them.

Geometric: character sets geometric constraints punctual as points coincidence, parallelism, tangential, collinear, perpendicularity, continuity, concentricity, flatness, symmetry, static, vertical and equality. controls
restriction also automatically display states the restrictions.

Dimensional: sizing sets restrictive elements, doing so constant distances and angles between drawing entities. we then linear constraints, horizontal, vertical, inclined, radial, diametral, angle and possibility of dimensioning transform entities restricted entities shoulder. This panel also controls the visibility of the restriction elements.

  • Object and Layer Properties


    See how new object and layer tools in AutoCAD 2009 can make your dreams come true. Quick Properties

    The new Quick Properties tool enables you to view and modify object properties in place, without having to go to the Properties palette. You can turn Quick Properties (QP) on or off from the status bar. After turning the feature on, simply select an object and the properties display for editing. You can control which properties are displayed for each object in the CUI (for speedy access select the Customize button in QP).

    The new Quick Properties tab in the Drafting Settings dialog box provides additional control.

    Layer Management

    The Layer Properties Manager is now modeless so you can keep it displayed as you use other commands. That means you can dock, autohide, or anchor it just like your other tool palettes. And it is now dynamic—any changes you make in the Layer Properties Manager are instantly applied to the drawing (no more “Apply”).

    For Using AutoCAD 2009

    SNAP MODE ON


    1. Left-click the SNAP MODE button in the Status Bar to turn ON the SNAP

    option.

    2. Move the cursor inside the graphics window, and move the cursor diagonally

    on the screen. Observe the movement of the cursor and watch the coordinates

    display at the bottom of the screen.

     The SNAP option controls an invisible rectangular grid that restricts cursor

    movement to specified intervals. When SNAP mode is on, the screen cursor and

    all input coordinates are snapped to the nearest point on the grid. The default snap

    interval is 0.5 inches, and aligned to the grid points on the screen.

    3. Click on the Line icon in the Draw toolbar. In the

    command prompt area, the message “_line Specify

    first point:” is displayed.

    4. On your own, create another sketch of the five-point star with the GRID and

    SNAP options switched ON.

  • Buttons in the status bar in Autocad

    A number of buttons in the status bar can be used for toggling (turning on/off) various functions when operating within AutoCAD.
    A click on a button turns that function on, if it is off; a click on a button when it is off turns the function back on. Similar results can be obtained by using function keys of the computer keyboard .
    SNAP: Also toggled using the F9 key. When set on, the cursor under mouse control can only be moved in jumps from one snap point to another. 
    GRID: Also toggled using the F7 key. When set on, a series of grid points appears in the drawing area. 
    ORTHO: Also toggled using the F8 key. When set on, lines etc. can be drawn only vertically or horizontally.
    POLAR: Also toggled using the F10 key. When set on, a small tip appears showing the direction and length of lines etc. in degrees and units.
    OSNAP: Also toggled using the F3 key. When set on, an osnap icon appears at the cursor pick box. 
    OTRACK: When set on, lines etc. can be drawn at exact coordinate points and precise angles.
    DYN: Dynamic Input. When set on, the x,y coordinates show as the cursor hairs are moved.
    LWT: When set on, lineweights show on screen. When set off, lineweights show only in plotted/printed drawings.
    MODEL: Toggles between Model Space and Paper Space. When in Paper Space an additional icon appears in the status bar. A click on the icon maximises the drawing area.

  • Right click and select Copy

    Although the MOVE and COPY commands provide more accuracy in a single image, we can use the Clipboard to move and copy objects from one image to another.
    We can also copy objects from one picture to another by using drag-and-drop.
    The easiest way is to open both images and then select the View tab> Windows panel> Tile Vertically> object.
    We select the object you want copied, navigate to one of the drawing area and drag the second image. However, here we do not have much control over the exact placement of the new object.


    To control the placement of objects that will be copied, steps should we do:
    - Select what you want We copy.
    - Right click and select Copy with base point on the shortcut menu.
    - Specify the base point with an object snap to become more precise.

  • Easily rotate an object

    We can easily rotate an object or objects to the base point is that we specify.
    Base point is usually the object snap points on an object to show the rotation and determining the rotation angle.
    By default, zero degrees is to the right, and the degree will be increased in the opposite direction.
    To change the default, select Application Button> Drawing Utilities> Units. By setting a negative angle, we can rotate the object clockwise.

    To rotate the object,
    select the Home tab> Modify panel> Rotate.
    Or, select an object and then select Rotate.
    At the Specify base point: prompt, shows a central point for the object that we play.
    At the Specify rotation angle or [Copy / Reference]: prompt, type the angle in the command line.

  • OOPS

    -Suppose that you had erased the wrong objects.
    -Before you DO ANYTHING ELSE, enter OOPS at the command line.
    -The erased objects will be returned to the screen.
    -Consider this in comparison to a traditional draughtsperson who has rubbed out
    -several lines/circles. They would have to redraw each one.

    OOPS restores objects erased by the last ERASE command.
    You can also use OOPS after BLOCK or WBLOCK because these commands can erase the selected objects after creating a block. However, you cannot use OOPS to restore parameters, actions, or grips in the Block Editor.
    You cannot use OOPS to restore objects on a layer that has been removed with the PURGE command.


    Notes:
    a) OOPS is used to restore objects erased by the LAST erase command.
    b) It must be used IMMEDIATELY after the last erase command.
    c) It must be entered from the keyboard.


    Command: e > enter
    ERASE
    Select objects: Specify opposite corner: 18 found > enter
    Select objects: > enter
    Command: OOPS > enter

  • Crosshairs in 3D

    If you’re planning to do any 3D modeling — and you should be, if you’re using AutoCAD 2007— set up the crosshair cursor for 3D so you’ll know which way is up. Use the Options command, and click the 3D Modeling tab.
    Select Show Z Axis In Crosshairs. Doing so adds the third “up” dimension to the crosshairs; it appears in blue. There is a method to the madness of color coding. Anyone who knows computers knows that monitors use RGB color space. Painters often get confused because they learned that yellow is a primary color, and it is — at
    least, for the subtractive color you see with reflected light (as in paint on a canvas). Computer monitors shine light in your eyes, so they use additive color,
    which is an entirely different animal. But we digress.
    The mnemonic, or way to remember it, is RGB=XYZ — red represents the X axis, green for Y, and blue for Z. The UCS icon is fatter and has conical arrowheads on the axis tips by default, but observe that it follows the same hard and fast color-coding rules.
    You might choose to label the axes on the crosshairs (in Options), but once you get the color mnemonic, doing so will be overkill. Before closing the 3D Modeling tab of the Options dialog, select Show Z Field For Pointer Input. This option is helpful if you ever want to key in Z coordinates on screen using dynamic input, but point input must also be enabled
    in Drafting Settings.

  • GRID ON

    Left-click the GRID button in the Status Bar to turn ON the GRID option. (Notice in the command prompt area, the message “” is also displayed.)
     Move the cursor inside the graphics window, and estimate the distance in between the grid points by watching the coordinates display at the bottom of the screen.
    The GRID option creates a pattern of dots
     that extends over an area on the screen. Using the grid is similar to placing a sheet of grid paper under a drawing. The grid helps you align objects and visualize
     the distance between them. The grid is not displayed in the plotted drawing. The default grid spacing, which means the distance in between two dots on the screen, is 1 mm. We can see that the sketched horizontal line in the above sketch is about 5 mm long.
