Object Snap Tracking (f11): creates temporary construction lines & tracking points, complete with text tips to inform you of acquired points & their relationship to each other. To use Osnap Tracking, you must turn on 1 or more object snaps.

**To track from an Osnap point, pause over the point while in a command. A tracking vector appears when you move the cursor. To stop tracking, pause over the point again.

User Profile A profile can be composed of, but not limited to, the fallowing settings and values: template drawing file location, text display format, arc and circle smoothness, start-up dialog box display, minutes between automatic saves, file extension for temporary files, AutoCAD screen menu display, colors and fonts for AutoCAD screen, type of pointer and length of crosshairs, and type of printer or plotter.
Steps to Create a User Profile
  1. Establish the settings you prefer.
  2. To save setting to a file: select Tools pulldown>Options>Profiles tab> Add to List button.
  3. Enter a name & description in the "Add Profile" dialog box.
  4. Pick the "Apply & Close" button to exit
  5. Select the profile you have just created by highlighting it: Pick the "Export" button, then select a folder location for the new file, enter a file name, and pick "Save". Note the file is given and .arg extension.
  6. In order to apply the profile the next time you run AutoCAD, it must be imported & displayed in the profile list box. Pick the "Import" button, select the proper ARG file, & then pick "Open".
  7. The imported file is displayed in the list. Select the file to highlight it, then pick the "Set Current" button.

***User profiles end in the extension .arg

Model Space

The Drawing Environment under the Model Tab or when a viewport is active.

***Note the USC icon used on model space

Paper Space

The Drawing Environment used to create plotting layouts.

***Note the USC icon used on paper space ( there is a triangular shape which identifies the Paper Space mode).

Layout A Layout is the manner in which a drawing is arranged in paper space. A layout may contain a title block, a sheet border, 1 or more viewports, & annotations. Each drawing can have multiple layouts, and the name of each layout is shown as a tab along the bottom of the drawing area.
Paper Space Guidelines
  1. Create a New Layer for the Floating Viewports & Make it current. (i.e. 0-VP).
  2. Go into Paper Space: Select the layout tab to make paper space the active drawing environment. The 1st time you select a layout, the Page Setup dialog box is displayed.
  3. Page Setup: In the Page Setup dialog box, select desired Plot device, Paper size, Drawing orientation, etc. Set the plot area = layout & plot Scale = 1:1. After selecting the OK button, Paper Space becomes the active drawing environment. A rectangular outline (shadow) indicates the paper size & the margins displayed within the paper (dashed lines) indicate the printable area of the paper for the current configured plotting device.
  4. Sheet Border & Title block: Insert a block for your Sheet border & Title block. Do this on the appropriate layer at a 1:1 scale.
  5. Create Floating Viewports.
MV

MVIEW: to make a floating viewport.

Note: Each time a new viewport is created, the model space drawing will be visible in the viewport.

V

View: Named Views.

Views may be saved under a name then recalled later by highlighting the name & making them current.

Icon for view is on the Standard toolbar.

Creating a View
  1. Select the "New" button on the dialog box.
  2. Name the view.
  3. Select the "Define" window button.
  4. Select the "Define View Window" button; then select a window in the graphic area of the view you want to save.
  5. Select the "OK" button.
Modifying Floating Viewport With paper space mode current, you can modify the viewports by using any of the AutoCAD modify commands, ie: stretch or scale (to change the size of the viewport); move (to move the viewport) or you can simply click on the viewport to make the grips appear, make a grip hot, then move it to get your new size/shape.
Viewports Toolbar

In the viewports toolbar "window", you can scale the viewport that is active.

When paper space is current, select the desired scale from the Viewports Toolbar window.

Display lock You can do this with a right click on 2002 or on properties (Display Locked under Alphabetic) on 2000 while in Layout Mode (the Paper button/tab must be on in the status bar).
PSLTSCALE

Controls paper space linetype scaling.

A system variable.

PSLTSCALE = 1 is the on position.

LTSCALE

Line Scale Factor.

A system variable.

LTSCALE = 1 is the on position.

-LA To invoke the layer command line: type –LA, then press enter. (note: by placing the hyphen in front of the command, you are able to invoke the command from the command line only, without a dialog box). From here you may copy/paste to notepad, then print for a hard copy.
ML

Multiline: consist of between 1 & 16 parallel lines, called elements.

Icon for it on Draw toolbar.

MLSYTLE Multiline Style: You can create styles for multilines to control the number of elements & the properties of each element.
I

Insert

Icon for it on Draw toolbar.

B

Block Definition, (BMAKE),(Block),or ( B) : A term of 1 or more AutoCAD objects that are combined to create a single object.

*** VERY IMPORTANT: Check your layers! The objects must be drawn on the zero layer if you want the block to inherit the linetype and color of the layer on which it is inserted.

W

Write Block, (Wblock), or (W): Creates drawing files. The Write Block command can be used to export symbols by writing them to new drawing files that can then be inserted in to any drawing.

Redefine a Block

When a block is redefined, all occurrences of the block in the drawing will be updated. One method of redefining a block within a drawing is to explode 1 of the blocks. Next, make the desired changes to the exploded block. Next, invoke the BLOCK command to create a block using the same name that the block had before it was exploded (arrow down in the name section on the Block Definition dialog box & select that name to prevent errors). Make sure & specify the same insertion point for the base point (otherwise all blocks will be shifted on the drawing).

TYPES OF BLOCKS:
  1. Full Size Block (ex: a chair block) Always insert at a scale of 1.

  2. 1" Block (ex: a door block) The insertion scale should be equal to the size of the door opening in inches.

  3. Symbol Block (ex: a light fixture block) Note: Symbol blocks should be drawn the size of the plotted object. Draw the block at a scale of 1:1. When inserting into a drawing, use the scale factor for the drawing as the insertion scale for the block.

A

Area: To calculate area and perimeter.

For 2002: turn on the "Inguiry" toolbar to find the AREA command.

For 2000: Icon for it on std toolbar in the "Inguiry" flyout.

Attributes

Attributes: are written or numerical values assigned to a block. The creation of attributes can be preformed with the "Attribute Definition" dialog box. After inserting a block, the value of the attributes may be changed with the "Edit Attributes" dialog box. Attribute information can be extracted from a drawing with the "Attribute Extraction" dialog box.

ATTDEF

Define Attributes: are written or numerical values assigned to a block. The creation of attributes can be preformed with the "Attribute Definition" dialog box. After inserting a block, the value of the attributes may be changed with the "Edit Attributes" dialog box. Attribute information can be extracted from a drawing with the "Attribute Extraction" dialog box.

ATTDIA

Attributes Dialog Box: Set the ATTDIA system variable to 1 in your drawing to automatically activate the ENTER ATTRIBUTES dialog box when you insert a block with attributes.

Steps to Create a Block

See handout and practice these steps a few times.

**** Don't forget to click the "Pick Point" box on the Attribute Definition dialog box before you click "Ok", once you have complete the first 6 steps.
