Use AutoCAD to find Object areas Distances between objects Time spent on a drawing

AREA DBLIST DIST ID LIST STATUS TIME

These commands are located under Menu: Tools Inquiry

Also on the Inquiry toolbar


5

Finding the Area of Shapes and ObjectsFinding the Area of Shapes and Objects


6

AREA CommandAREA Command

AREA Can be used to find the area of any

Object Circle Polyline Polygon Spline.7


7


The AREA Command Command Alias: AA

Select by Command: AREA Menu: Tools; Inquiry; AREA Toolbar: Inquiry


8


Command: AREA Command: Area Specify first corner point or

[Object/Add/Subtract]: Specify next corner point or press ENTER for

total: Area = 5.9962, Perimeter = 10.3937 Command:


9


Object Value Returned Line (no area possible) Polyline Length or perimeter Circle Circumference Spine Length or perimeter Rectangle Perimeter


10


AutoCAD gives the area inside three or more points picked on the screen and also gives the perimeter. The areas do not have to be connected with

lines.


11


Shapes drawn with lines or polylines do not need to be closed for AutoCAD to calculate the area.

AutoCAD calculates the area as if a line connects the first and last points.


12


To calculate Areas Drawn With Lines Pick all vertices of the shape (the endpoints of

the lines). Use OSNAP


13

The ADD OptionThe ADD Option

The ADD option of the AREA Command adds areas to calculate a total area.


14

The SUBTRACT OptionThe SUBTRACT Option

The SUBTRACT option of the AREA Command subtracts areas to calculate a total area.


15

Listing Drawing Data – Listing Drawing Data – The LIST CommandThe LIST Command


16

The LIST Command The LIST Command

The LIST Command allows you to display data about any AutoCAD object.


17


Information that can be obtained: Line lengths. Coordinates. Circle and arc locations and radii. Polyline widths. Object Layers. Insertion points.


18


The LIST Command Command Aliases: LI, LS

Select by Command: LIST Menu: Tools; Inquiry; LIST Toolbar: Inquiry


19


Command: LIST Pick the object(s) Press [Enter]


20


LIST is the most powerful inquiry command in

AuotCAD. It provides all the information you need to

know about an object.

LIST also reports the area and perimeter of polylines so you do not need to use the AREA command.


21

The LIST Command The LIST Command LIST also gives

information about text. Text

Layer Space (model or paper) Handle Style Annotative (yes or no) Font file = name Start point (x, y, z) Height Text Rotation Width scale factor Obliquing Generation

MTEXT Layer Space (model or paper) Location Width Norma Rotation Text Style Annotative Text height


22

Listing Drawing Date for All Objects – Listing Drawing Date for All Objects – The DBLIST CommandThe DBLIST Command


23

The DBLIST Command The DBLIST Command

DBLIST gives information about all items in the drawing. The information passes by a screen full at a

time. Press [Enter] to see the next screen. Press [F2] to exit the text window.

DBLIST gives TOO MUCH information for most situations.


24

Finding the Distance Between Two Finding the Distance Between Two Points – The DIST CommandPoints – The DIST Command


25

The DIST Command The DIST Command

DIST gives the distance between two points. (Use object snap to improve accuracy)

DIST reports Distance Delta X, Delta Y, and Delta Z


26


The DIST Command Command Alias: DI

Select by Command: DIST Menu: Tools; Inquiry; DIST Toolbar: Inquiry


27


Command: DIST Specify first point: (select point) Specify second point: (select second point)


28

Identifying Point LocationsIdentifying Point Locations


29

The ID Command The ID Command

The ID command gives the coordinate location of a single point

on the screen. Can be used to find coordinates of

A line endpoint The center of a circle


30


The ID command Has no Command Alias

Select by Command: DIST Menu: Tools; Inquiry Toolbar: Inquiry


31


Command: ID Specify point: (select point) X = n.nnnn Y = n.nnnn Z = n.nnnn


32


The ID command will also place a “blip” on the screen at coordinates that you specify.

Command: ID Specify point: 8.75,6.44 X=8.5 Y=6.44 Z=0.00

Blipmode system variable must be on!


33

Checking the Time – The TIME Checking the Time – The TIME Command Command


34

The TIME Command The TIME Command

The TIME command allows you to:

Display the current time. The time related to your drawing. The time related to the current drawing session.


35


The TIME command Has no Command Alias

Select by Command: TIME Menu: Tools; Inquiry, TIME


36


Command: TIME Enter option [Display/ON/OFF/Reset]:

Current time: Saturday, April 30, 2011 10:10:26:548 AM Times for this drawing: Created: Saturday, April 30, 2011 9:57:09:968 AM Last updated: Saturday, April 30, 2011 9:57:09:968 AM Total editing time: 0 days 00:13:16:971 Elapsed timer (on): 0 days 00:13:16:596 Next automatic save in: <no modifications yet>


37


The drawing creation time starts when 1. You begin a new drawing (not when a

drawing is first saved) OR

2. You issue the WBLOCK command.


38


A SAVE command affects the Last Updated: time.

If you exit AutoCAD and do not save the drawing, all time in that drawing session is discarded (not counted).


39


You can time a specific drawing task by using the TIME command.

Use the Reset Option.


40


When the TIME command is issued, the times shown in the text window are static. None of the times are being updated.

You can update the time by using the Display Option.


41


The TIME timer is ON by Default. TO stop the time, enter OFF at the Enter

option prompt: [Display/ON/OFF/Reset]

Enter ON to start the timer again.


42

Determining the Drawing Status – The Determining the Drawing Status – The STATUS CommandSTATUS Command


43

The STATUS CommandThe STATUS Command

The STATUS command gives general information about the current

drawing including Current drawing extents. Settings of various drawing modes and

parameters. Free physical memory and disk space.


44


The STATUS command Has no Command Alias

Select by Command: STATUS Menu: Tools; Inquiry; STATUS


45


To display a drawing's status information, from the Tools menu, choose Inquiry Status.

AutoCAD displays the report.


46


STATUS reports the number of objects in the current drawing including: Graphical objects:

Arcs Polylines

Non-graphical objects Layers Linetypes Block definitions.


47


When used at the DIM prompt, STATUS reports the values and descriptions of all dimensioning system variables.

limit's lower-left corner, stored in the LIMMIN system variable.

The second line shows the XY coordinate of the limit's upper-right corner, stored in the LIMMAX system variable.

The notation Off to the right of the Y coordinate value indicates that limits checking is set to 0.


52


Model or Paper Space Uses Displays the drawing extents, which includes

all objects in the database and can exceed the drawing limits.

The first line shows the XY coordinate of the lower-left corner of the extents.

The second line shows the XY coordinate of the upper-right corner.


53


Model or Paper Space Uses The notation Over to the right of the Y

coordinate value indicates that the drawing extends outside the drawing limits.


54


Display Shows Lists the portion of the drawing extents visible

in the current viewport. The first line shows the XY coordinate of the

display's lower-left corner. The second line shows the XY coordinate of

the upper-right corner.


55


Insertion Base Is Displays the insertion point of the drawing,

stored in the INSBASE system variable and expressed as an X,Y,Z coordinate.

Snap Resolution Is Displays the snap spacing in the X and Y

directions, stored in the SNAPUNIT system variable.


56


Grid Spacing Is Displays the grid spacing in the X and Y

directions, stored in the GRIDUNIT system variable.

Current Space Shows whether model space or paper space

is active.


57


Current Layer Lists the current layer of the drawing, stored

by the CLAYER system variable.

Current Color Lists the current color, stored by the

CECOLOR system variable.


58
