4 | Chapter 1 Find the Information You Need

Use Searches

A basic search using the Search tab consists of the word or phrase you want to find. The basic search rules are as follows:
Type your search in uppercase or lowercase characters; searches are not
case-sensitive.
Search for any combination of letters (a-z) and numbers (0-9).
Do not use punctuation marks such as the period, colon, semicolon,
comma, hyphen, and single quotation marks; they are ignored during a search.
Group the elements of your search using double quotation marks or
parentheses to set each element apart.
Note When you use the Search tab, all topics that contain the word or phrase
that you specify are listed. This includes the text in topic titles and labels, not just the topic text.
Use Advanced Search
Advanced full-text search on the Search tab allows you to search using Bool­ean operators and wild cards. You can limit the search to previous results, match similar words, or search topic titles only. When searching for multi­word topics, use double quotation marks (" ") to enclose words that must appear next to each other in the specified sequence. For example, enter "specifying units of measurement" to find only topics with all those words in that order. If you don’t use the quotation marks around that text, Help finds all topics containing any one of the listed words, that is, all topics containing "specifying", all topics containing "units", all topics containing "of", and all topics containing "measurement".
With the AND, OR, NOT, and NEAR operators, you can precisely define your search by creating a relationship between search terms. The following table shows how you can use each of these operators. If no operator is specified, AND is used. For example, the query "spacing border printing" is equivalent to "spacing AND border AND printing".
Search for Example Results
Both terms in the same topic
Either term in a topic "raster" OR "vector" Topics containing either the word
"tree view" AND "palette"
Topics containing both the words "tree view" and "palette"
"raster" or the word "vector" or both
Use the Help System Efficiently | 5
Search for Example Results
The first term without the second term
Both terms in the same topic, close together
"ole" NOT "dde" Topics containing the word "OLE," but
not the word "DDE"
"user" NEAR "kernel" Topics containing the word "user"
within eight words of the word "kernel"
Note The |, &, and ! characters do not work as Boolean operators. You must
use AND, OR, and NOT.
To search for information in Help
1 Choose the Search tab and then enter the word or phrase you want to
find. To use Boolean operators to refine your search:
Click to add Boolean operators to your search.
Enter the word or phrase you want to appear after the Boolean
operator.
You can also use the check boxes at the bottom of the Search tab to further refine your search:
Search previous results. Refines a search by applying new search
criteria to the results of a previous search.
Match similar words. Expands the search to include words similar to
your search criteria, rather than limiting the search to exact matches.
Search titles only. Limits the search to topic titles, rather than search-
ing titles and topic contents.
2 Choose List Topics, select the topic you want, and then choose Display. 3 To sort the topic list, click the Title, Location, or Rank column heading.
To view only procedures, click the Title column heading and scroll down to the items that begin with the word “To.”

Use Ask Me

You can find information by typing a question phrased in everyday language. You can perform this natural language query in Help by choosing the Ask Me tab and entering a question, a word, or a phrase. For example, you could enter: How do I create a layout?
6 | Chapter 1 Find the Information You Need
The results of natural language queries are often more accurate than the results of searches. Matching topics are ranked by percentages that reflect how likely they are to answer your questions.
You can also expand your natural language query to the Web.
To use natural language queries in Help
1 Choose the Ask Me tab, and then enter the question you want answered.
Alternatively, you can enter a phrase or a single word.
2 To narrow query results, select a particular item or set from the List of
Components to Search.
3 Click the link for the topic you want to display.
Note For hints on obtaining good query results, click the Query Tips link on
the Ask Me tab.
To expand your queries to the Web
Use this procedure if the results of a natural language query did not provide the information you needed.
1 Scroll to the bottom of the list of matching topics that resulted from your
query.
2 Click the Search the Web link at the bottom of the list.
A web search engine displays the results of your search.
Note For hints on obtaining good query results, click the Query Tips link on
the Ask Me tab.

Understand How Help Topics Are Organized

Most topics in the Help system have three tabs above the right pane of the Help window. The tabs display different types of information.
Concepts. Describes an AutoCAD feature or function. When you click a
concept tab, notice that the Help Contents list in the left pane of the Help window expands and highlights the current topic. The Contents tab dis­plays the structure of the Help on that topic. You can easily display nearby topics by clicking them in the list.
Use the Help System Efficiently | 7
Procedures. Provides step-by-step instructions for common procedures
related to the current topic. After displaying a procedure, you can click the Procedures tab to redisplay the current list of procedures.
Reference. Lists commands and system variables related to the current
topic, with links to detailed descriptions of related commands. If you click an entry on the Reference tab, the Command Reference opens to the com­mand or system variable that you selected.
When you click a different tab, the topic remains the same. Only the type of information displayed--concepts, procedures, or reference links--is different.
Concepts Tab Organization
In the Concepts tab, there are two types of information displayed: navigation text and destination text. Navigation text displays links with short descrip-
tions. The purpose of navigation text is to guide you step-by-step to the infor­mation that you need. The links on navigation pages lead to additional nav­igation pages deeper in the Help structure until you come to a destination page. Each link is designed to provide you with more detailed information.
Procedures Tab and Reference Tab Organization
As you navigate deeper into the Help structure, the corresponding informa­tion on the Procedures tab and on the Reference tab becomes more specific, and the number of entries displayed on each tab decreases.
To change the type of Help information displayed
Choose the Concepts, Procedures, or Reference tab to change the type of
information displayed in the right pane of the Help window.

Use the Up Arrow to Navigate Help Topics

An up arrow may be displayed in the upper right corner of a topic.
Click this arrow to move up a level from the current topic to a topic that con­tains a broader scope of information.

Print Help Topics

The quickest way to print the current topic is to right-click within the topic and choose Print.
The Print button on the Help toolbar provides these print options:
Print the selected topic (recommended)
Print the selected heading and all subtopics
8 | Chapter 1 Find the Information You Need
Note When you select the second option, you may get numerous printed
pages, depending on how many subtopics the currently selected topic contains.
To print a Help topic
1 Display the topic you want to print. 2 Right-click in the topic pane and select Print. 3 In the Print dialog box, choose OK.
To print a selected heading and all subtopics
1 Display the topic you want to print and make sure that the Contents tab
is showing.
2 On the Help toolbar, choose the Print button. 3 In the Print Topics window, select Print a Selected Heading and All
Subtopics.
4 Choose OK.

Show and Hide the Contents Pane

You can shrink the Help window to a compact size by hiding the pane that contains Help Contents, Index, Search, Favorites, and Ask Me tabs. The com­pact window size is best for displaying procedures while you work.
You can expand the Help window to display the pane that contains Help Contents, Index, Search, Favorites, and Ask Me tabs. The expanded window size is best for locating and displaying conceptual and reference information.

Menus, Toolbars and Tool Palettes
AutoCAD® provides menus, shortcut menus, toolbars,
and tool palettes for access to frequently used
commands, settings, and modes. The Standard, Object
Properties, Draw, and Modify toolbars are displayed by
default. Shortcut menus display commands that are
relevant to your current activity. Tool palettes provide
an efficient method for organizing and placing blocks
and hatches.

Tool Palettes

Tool palettes are tabbed areas within the Tool Palettes window that provide an efficient method for organizing, sharing, and placing blocks and hatches. Tool palettes can also contain custom tools provided by third-party developers.
Insert Blocks and Hatches Using Tool Palettes
Tool palettes are tabbed areas within the Tool Palettes window. You can place blocks and hatches that you use often on a tool palette. When you need to add a block or a hatch to a drawing, drag it from the tool palette onto your drawing.
Blocks and hatches that reside on a tool palette are called tools, and several tool properties including scale, rotation, and layer can be set for each tool individually.
Blocks that are placed with this method often must be rotated or scaled after they are placed. You can use object snaps when dragging blocks from a tool palette, however grid snap is suppressed during dragging.
Scale Blocks Automatically
When a block is dragged from a tool palette into a drawing, it is scaled auto­matically according to the ratio of units defined in the block and defined in the current drawing. For example, if the current drawing uses meters as its units and a block is defined using centimeters as its units, the ratio of the units is 1 m/100 cm. When the block is dragged into the drawing, it is inserted at 1/100 scale.
Note In the Options dialog box, User Preferences tab, the Source Content
Units and Target Drawing Units settings are used when, either in the source block or the target drawing, the Drag-and-Drop Scale is set to Unitless.

You can change the insertion properties or pattern properties of any tool on a tool palette. For example, you can change the insertion scale of a block or the angle of a hatch pattern.
To change these tool properties, right-click a tool and click Properties on the shortcut menu. Then you change the tool’s properties in the Tool Properties dialog box. The Tool Properties dialog box has two categories of properties— the Insert or Pattern properties category, and the General properties category.
Insert or Pattern properties. Control object-specific properties such as
scale, rotation, and angle.
General properties. Override the current drawing property settings such
as layer, color, and linetype.
Tool Palettes | 23
Update the Icon for a Tool
Icons in tool palettes are not automatically updated if the block or hatch changes. If you change a block or hatch definition you can update its icon in a tool palette. In the Tool Properties dialog box, change the entry in the Source File field for blocks or the Pattern name field for hatches, and then change the entry back again. This forces an update of the icon for that tool.
Alternatively, you can delete the tool and then replace it using DesignCenter.
Specify Overrides for Tool Properties
In some cases, you may want to assign specific property overrides to a tool. For example, you may want a hatch to be placed automatically on a pre-spec­ified layer, regardless of the current layer setting. This feature can save you time and reduce errors by setting properties automatically when creating certain objects.
The Tool Properties dialog box provides fields for each potential property override.
Layer property overrides affect color, linetype, lineweight, plot style, and plot. Layer property overrides are resolved as follows:
If a layer is missing from the drawing, that layer is created automatically.
If a layer to which you are dragging a block or hatch is currently turned
off or frozen, the layer is temporarily turned on or thawed.
To display the properties of a tool on a tool palette
1 On a tool palette, right-click a tool and then click Properties on the short-
cut menu.
2 In the Tool Properties dialog box, use the scroll bar to view all tool
properties. You can also resize the Tool Properties dialog box or expand and collapse

Customize Tool Palettes
You can create new tool palettes using the Properties button on the title bar of the Tool Palettes window. Add tools to a tool palette with the following methods:
Drag drawings, blocks, and hatches from DesignCenter to the tool palette.
Drawings that are added to a tool palette are inserted as blocks when dragged into the drawing.
Use Cut, Copy, and Paste to move or copy tools from one tool palette to
another.
Create a pre-populated tool palette tab by right-clicking a folder, a draw-
ing file, or a block in the DesignCenter tree view, and then clicking Create Tool Palette on the shortcut menu.
Tool Palettes | 25
Note For block tools on tool palettes, the source drawing files must always be
accessible. If a source drawing file is moved to a different folder, you must modify the block tool that references it by right-clicking the block tool and, in the Tool Properties dialog box, specifying the new source file folder.
Once tools are placed in a tool palette, you can rearrange them by dragging them within the tool palette.
A tool palette tab can be moved up and down the list of tabs from the tool palette shortcut menu, or from the Tool Palettes tab of the Customize dialog box. Similarly, you can delete tool palettes that you no longer need. Tool pal­ettes that are deleted are lost unless they are first saved by exporting them to a file. You can control the path to your tool palettes on the Files tab in the Options dialog box. This path can be to a shared network location.
Note If a tool palette file is set with a read-only attribute, a lock icon displays
in a lower corner of the tool palette. This indicates that the tool palette cannot be modified beyond changing its display settings and rearranging the icons.

Toolbars

Toolbars contain buttons that start commands. When you move the point­ing device over a toolbar button, the tooltip displays the name of the button. Buttons with a small black triangle in the lower-right corner have flyouts that contain related commands. With the cursor over the icon, hold down the pick button until the flyout appears.
The Standard toolbar at the top of the drawing area is displayed by default. This toolbar is similar to those found in Microsoft Office programs. It con­tains frequently used AutoCAD commands such as well as Microsoft Office standard commands such as New, Open, and Save.
Display, Dock, and Resize Toolbars
AutoCAD initially displays several toolbars:
Standard toolbar
Styles toolbar
Layers toolbar
Properties toolbar
Draw toolbar
Modify toolbar

You can display or hide these four and additional toolbars, and you can create your own toolbars. A toolbar can be floating or docked. A floating tool­bar is located anywhere in the drawing area of the AutoCAD window, and you can drag it to a new location, resize it, or dock it. A docked toolbar is attached to any edge of the drawing area. While a toolbar is docked, it cannot be resized. You can move a docked toolbar by dragging it to a new docking location.

To enter a command by using the keyboard, type the full command name on the command line and press device.
Some commands also have abbreviated names. For example, instead of entering circle to start the command names are called command aliases and are defined in the acad.pgp file. To define your own command aliases, see “Create Command Aliases” in the Customization Guide.
Specify Command Options
When you enter commands on the command line, AutoCAD displays either a set of options or a dialog box. For example, when you enter circle at the Command prompt, the following prompt is displayed:
Specify center point for circle or [3P/2P/Ttr (tan, tan, radius)]:
You can specify the center point either by entering X,Y coordinate values or by using the pointing device to click a point on the screen.

Interrupt a Command with Another Command or System Variable
Many commands can be used transparently: that is, they can be entered on the command line while you use another command. Transparent commands frequently change drawing settings or display options, for example,
ZOOM. In the Command Reference, transparent commands are designated by
GRID or
an apostrophe in front of the command name.
To use a command transparently, choose its toolbar button or enter an apos­trophe (') before entering the command at any prompt. On the command line, double angle brackets (>>) precede prompts that AutoCAD displays for transparent commands. After you complete the transparent command, the original command resumes. In the following example, you turn on the dot grid and set it to one-unit intervals while you draw a line, and then you continue drawing the line.
Command: line Specify first point: 'grid >>Specify grid spacing (X) or [ON/OFF/Snap/Aspect] <0.000>: 1 Resuming
LINE command
Specify first point:
Commands that do not select objects, create new objects, or end the drawing session usually can be used transparently. Changes made in dialog boxes that you have opened transparently cannot take effect until the interrupted com­mand has been executed. Similarly, if you reset a system variable transpar­ently, the new value cannot take effect until you start the next command.

Enter System Variables on the Command Line

System variables are settings that control how certain commands work. They can turn on or turn off modes such as Snap, Grid, or Ortho. They can set default scales for hatch patterns. They can store information about the current drawing and about AutoCAD configuration. Sometimes you use a system variable in order to change a setting. At other times you use a system variable to display the current status.
For example, the and off when you change the value. In this case, the variable is functionally equivalent to the system variable that stores the current date. You can display this value, but you cannot change it.
You can examine or change a system variable's setting transparently, that is, while using another command; however, new values may not take effect until the interrupted command ends.

Switch Between Dialog Boxes and the Command Line

Some functions are available both on the command line and in a dialog box. In many cases, you can enter a hyphen before the command to suppress the dialog box and display prompts on the command line instead. For example, entering layer on the command line displays the Layer Properties Manager. Entering -layer on the command line displays the equivalent command line options. Suppressing the dialog box is useful for compatibility with earlier versions of AutoCAD and for using script files. There may be slight differ­ences between the options in the dialog box and those available on the command line.
These system variables also affect the display of dialog boxes:
ATTDIA controls whether INSERT uses a dialog box for attribute value entry.
CMDNAMES displays the name (in English) of the currently active com-
mand and transparent command.
EXPERT controls whether certain warning dialog boxes are displayed.
FILEDIA controls the display of dialog boxes used with commands that
read and write files. For example, if Save Drawing As dialog box. If on the command line. The procedures in this documentation assume that
FILEDIA is set to 1. Even when FILEDIA is set to 0, you can display a file
dialog box by entering a tilde (~) at the first prompt.
FILEDIA is set to 1, SAVEAS displays the
FILEDIA is set to 0, SAVEAS displays prompts
FILEDIA and EXPERT are useful when you use scripts to run commands.
To use the command line version of a command
For most commands, enter minus (-) in front of the command.
For dialog boxes that open and save files, set the FILEDIA system variable
to 0.

Dock and Resize the Command Window

By default, the command window is docked. The docked command window is the same width as the AutoCAD window. If text that is entered becomes longer than the width of the command line, the window pops up in front of the command line to show the full text of the line.
You can resize the window vertically by dragging the splitter bar, which is located on the top edge of the window when it is docked on the bottom and at the bottom edge of the window when it is docked at the top.
Undock the command window by dragging it away from the docking region. When you undock the window, the floating window is the size it was before you undocked it. You can move the floating command window anywhere on the screen and resize its width and height with the pointing device.
Dock the command window by dragging it until it is over the top or bottom docking regions of the AutoCAD window.
To float the command window
Click the move handle on the left edge of the docked command window
and drag the command window away from the docking region until it has a thick outline. Then drop it in the drawing area of the AutoCAD window.

The selected profile is in effect only for the current session of AutoCAD, unless you make another profile current in the Options dialog box during that session. You create or import Profiles on the Profiles tab in the Options dialog box. With the /p switch, you can only specify those profiles that are listed in the Options dialog box. If the profile does not exist, AutoCAD uses the current profile.
The syntax for using command line switches is
"drive:pathname\acad.exe" ["drawing name"] [/switch "name"]
When using a switch option, you must follow the switch with a space and then the name of a file, path, or view within quotation marks. For example the following entry starts AutoCAD from a folder named AutoCAD 2002 with the template drawing arch1.dwt, restores a named view
PLAN1, and executes
a script file startup.scr.
"d:\AutoCAD 2002\acad.exe”/t "d:\AutoCAD 2002\template\arch1" /v "plan1" /b "startup"
AutoCAD resolves the environment settings in the following way:
If you use a command line switch to specify an environment setting, the
command line switch overrides the settings specified in either the Options dialog box or the environment variable.
If a command line switch is not set, the corresponding value set in the
Options dialog box is used.
If neither a command line switch nor an Options value is set, the environ-
ment variable value is used.
Note Command line switches and environment variables override Options
values for the current session only. They do not alter the system registry.

To start AutoCAD with a command line switch
1 Right-click the AutoCAD icon on the Windows Desktop. Then choose
Properties.
2 In the AutoCAD Properties dialog box, choose the Shortcut tab. 3 In the Target box, edit the parameters for the switch using the following
syntax:
"drive:pathname\acad.exe" ["drawing name"] [/switch "name"]
Valid switches: /b Script name (b stands for batch process) /t Template file name /c Configuration folder /v View name /s Support folders /r Default system pointing device /nologo No AutoCAD logo screen /p User-defined registry profile For example, enter "d:\AutoCAD 2002\acad.exe" /t "d:\AutoCAD
2002\template\arch1" /v "plan1" /b "startup"
4 Choose OK.

Save and Restore Profiles

You can use the Profiles tab in the Options dialog box to create and save your drawing environment settings as a profile. If you share your workstation with other users who use the same login name, you can restore your options by making the profile current. You can also create and save profiles to use with different projects. By default, AutoCAD stores your current options in a profile named name, as well as the current drawing name, in the Options dialog box.
The profile information is stored in the system registry and can be saved to a text file (an ARG file). AutoCAD organizes essential data and maintains changes in the registry as necessary.
66 | Chapter 5 Customize the Drawing Environment
UNNAMED PROFILE. AutoCAD displays the current profile
Once you save a profile, you can export or import the ARG file to and from different computers. If you make changes to your current profile during an AutoCAD session and you want to save those changes in the ARG file, you must export the profile. When you export the profile with the current profile name, AutoCAD updates the ARG file with the new settings. You can import the profile again into AutoCAD to update your profile settings.

The Wheel Mouse
The wheel mouse has a small wheel between the buttons. The left and right buttons behave the same as they do on a standard mouse. You can rotate the wheel by discrete values. You can use the wheel to zoom and pan in your drawing without using any AutoCAD commands.
By default, the zoom factor is set to 10 percent; each increment in the wheel rotation changes the zoom level by 10 percent. The
ZOOMFACTOR system
variable controls the incremental change, whether forward or backward. The higher the number, the larger the change.

To practice using several features of the mouse
1 Move your mouse and notice that the pointer on the screen changes from
crosshairs while the pointer is in the drawing area, to an arrow when it's not over the graphics area, and to an I-beam when it's in the text window.
2 As you continue to move the mouse, notice that the numbers in the
coordinate display on the status bar change. These numbers indicate the exact location, or coordinate, of the crosshairs on the screen. Click in the coordinate display to turn it off. Notice that the coordinates are updated only when you click in the graphics area.
3 Find the Snap button on the status bar and click it with the pick button
on your mouse (usually the left button). Notice that the button darkens to indicate that Snap mode has been turned on.
4 Move the pointer around the screen and observe that it seems to adhere,
or "snap," to points at predetermined and equivalent intervals on the screen. You can change the size of these intervals.
5 Click the Snap button again to turn Snap mode off. 6 Move the pointer over the Standard toolbar at the top of the graphics area.
As you leave the pointer over a button for a few moments, notice a pop­up label, called a tooltip, that identifies the button.
7 Move the pointer over double bars at the end of a toolbar. Then, as you
hold down the pick button, drag the toolbar around the screen to reposition it.
8 Dock the toolbar by dragging it to a docking location at the top, bottom,
or either side of the drawing area. When the outline of the toolbar appears in the docking area, release the pick button.

Digitizing Tablets

A digitizing tablet, or digitizer, is a peripheral device that can be used to trace paper drawings into an AutoCAD drawing file or to choose commands from the digitizing tablet overlay supplied with AutoCAD. With the Wintab driver, the tablet pointer can also be used instead of a mouse as a system pointer to choose menu items and drawing objects in AutoCAD or to interact with the operating system. The tablet pointer can be a puck or a stylus.
The digitizing tablet must first be configured and then can optionally be calibrated.
When the tablet is configured, portions of the tablet surface are designated
as menu areas and a screen-pointing area.
When the tablet is calibrated, it can be used to trace geometry from an
existing paper drawing or photograph into an AutoCAD drawing.
You can easily switch between using the tablet uncalibrated as a system pointer (Tablet mode off) or calibrated for digitizing a drawing (Tablet mode on). Click the Tablet button on the status bar. If a screen-pointing area has been designated, a Float button is displayed on the status bar and toggles the screen-pointing area on and off.

Start and Save a Drawing
You can start a new drawing several ways. You can use a
wizard to step you through the process, you can start
from scratch using default settings, or you can start
from a template file with a preset environment. In each
case, you can choose the conventions and defaults you
want to use.

Start a Drawing from Scratch

A quick way to begin a new drawing is to start from scratch, which starts a drawing that uses settings from a default drawing template file.
You can start from scratch from the Create New Drawing dialog box, from the Select Template dialog box, or without using a dialog box at all. In each case, you use either the
Use the Create New Drawing Dialog Box
The Create New Drawing dialog box is displayed under the following conditions:
You set the STARTUP system variable to 1 (on).
You set the FILEDIA system variable to 1 (on).
You click New on the File menu or Qnew on the Standard toolbar when
no drawing template file is specified in the Options dialog box.
The Create New Drawing dialog box provides several methods for starting a new drawing.
When you use Start from Scratch, you can specify either imperial or metric units for the new drawing. The setting you select determines default values used for many system variables controlling text, dimensions, grid, snap, and the default linetype and hatch pattern file.
Imperial. Creates a new drawing based on the imperial measurement
system. The drawing uses internal default values, and the default drawing boundary, called the drawing limits, is 12 × 9 inches.
Metric. Creates a new drawing based on the metric measurement system.
The drawing uses internal default values, and the default drawing bound­ary is 429 × 297 millimeters.
NEW command or the QNEW command.
Use the Select Template Dialog Box
The Select Template dialog box is displayed under the following conditions:
You set the STARTUP system variable to 0 (off).
You set the FILEDIA system variable to 1 (on).
You click New on the File menu or, by default, Qnew on the Standard
toobar.
At the bottom-right corner of the Select Template dialog box, there is an Open button with an arrow button next to it. If you click the arrow button, you can choose between two internal default drawing templates, metric or imperial.
78 | Chapter 7 Start and Save a Drawing
Use a Default Drawing Template File
The fastest way to begin working on a new drawing is to start automatically with a default drawing template file. No dialog box is displayed with this method:
You set the STARTUP system variable to 0 (off).
You set the FILEDIA system variable to 1 (on).
You specify a default drawing template file in the Options dialog box on
the Files tab. Click the node labeled “Drawing Template Settings” and specify a path and drawing template file.
You click Qnew on the Standard toolbar.
From now on, a new drawing is immediately created that is based on the specified default drawing template file.
If no template file is specified in the Options dialog box, QNEW displays the Select Template dialog box.
To start a drawing from scratch with the Create Drawing dialog box
1 If necessary, set the
STARTUP system variable to 1 and the FILEDIA system
variable to 1. On the command line, enter startup and 1; then enter filedia and 1.
2 On the File menu, click New. 3 In the Create New Drawing dialog box, click Start from Scratch. 4 Under Default Settings, click either Imperial or Metric.
The new drawing starts as drawing1.dwg. The default drawing name changes to reflect the number of new drawings that have been started. For example, if you start another drawing, the default drawing name is drawing2.dwg.

Use a Template File to Start a Drawing

A drawing template file contains standard settings. Select one of the template files supplied, or create your own template files. Drawing template files have a .dwt file extension.
When you create a new drawing based on an existing template file and make changes, the changes in the new drawing do not affect the template file. You can use one of the template files supplied with AutoCAD, or you can create your own template files.
Create a Drawing Template File
When you need to create several drawings that use the same conventions and default settings, you can save time by creating or customizing a template file instead of specifying the conventions and default settings each time you start. Conventions and settings commonly stored in template files include
Unit type and precision
Title blocks, borders, and logos
Layer names
Snap, Grid, and Ortho settings
Drawing (grid) limits
Dimension styles
Text styles
Linetypes
By default, drawing template files are stored in the template folder, where they are easily accessible.
Recover the Default Drawing Template File
If the settings in the AutoCAD
®
drawing template files acad.dwt or acad-
iso.dwt have been changed from the original defaults, you can reset them by starting a new drawing with no template and then saving the drawing as a drawing template file, replacing acad.dwt or acadiso.dwt.
You can start a new drawing with the original defaults by using

Command line

Save a Drawing

You save drawing files for later use just as you do with other Windows appli­cations. AutoCAD also provides automatic saving, backup files, and other options for saving.
When you are working on a drawing, you should save it frequently. Saving protects you from losing work in the event of a power failure or other unex­pected event. If you want to create a new version of a drawing without affecting the original drawing, you can save it under another name.
The file extension for AutoCAD drawing files is .dwg, and unless you change the default file format in which drawings are saved, drawings are saved in the AutoCAD LT 2004 drawing-file format. This format is optimized for file com­pression and for use on a network.
Save Your Drawing Automatically
If you turn on the automatic saving option, AutoCAD saves your drawing at specified time intervals. By default, files saved automatically are temporarily assigned the name filename_a_b_nnnn.sv$. The file name is the current drawing name, a is the number of open instances of the same drawing file in the same AutoCAD session, b is the number of open instances of the same drawing in different sessions of AutoCAD, and nnnn is a random number generated by AutoCAD.
NEW
Files that are automatically saved are deleted when AutoCAD closes a drawing in the normal way. Saved files remain in the event of a crash or power failure. To recover a previous version of your drawing from the auto­matically saved file, rename the file using a .dwg extension.
Save a Drawing | 83
Use Backup Files
If you turn on automatic backups, AutoCAD saves the previous version of your drawing files to a file with the same name and a .bak file extension. To recover the previous version of your drawing from a backup file, rename the file using a .dwg extension.
Save Part of a Drawing File
If you want to create a new drawing file from part of an existing drawing, you can use
BLOCK or WBLOCK. With either command, you can select objects or
specify a block definition in your current drawing and save them in a new drawing file. You can also save a description along with the new drawing.
Save to a Different Type of Drawing File
You can save a drawing to an earlier version of the DWG or DXF format or save a drawing as a template file. Choose the format from Files of Type in the Save Drawing As dialog box.
Reduce the Time Required to Save a Drawing File
You can reduce the time required to save a drawing file if you specify incre­mental saves rather than full saves. An incremental save updates only those portions of the saved drawing file that you changed.
When you use incremental saves, drawing files will contain a percentage of potentially wasted space. This percentage increases after each incremental save until it reaches a specified maximum, at which time a full save is per­formed instead. You can set the incremental save percentage in the Open and Save tab of the Options dialog box or by setting the value of the system vari-
ISAVEPERCENT. If you set the value of ISAVEPERCENT to 0, all saves are full
able saves.
To reduce the size of drawing files, it is recommended that you perform a full save (with
IPERCENTSAVE set to 0) before transmitting or archiving a drawing.
