1. Setting up the drawing

There are two main ways to tell the program what to do. One way is to find a certain command on the tool baror under one of the options on top of your window (File, Edit, View, Insert, Format, Tools). The second way

is by typing up the command in the Command Line. The directions below will provide the information on bothways.

1.Drawing Units Drawing Units set up the current format for units of measure. In order to set up the drawing units, Go:Format menu: Units You will now have a choice between Architectural, Decimal, Engineering, Fractional, and Scientific Units.The Engineering and Architectural formats produce feet-and-inches displays and assume that each drawingunit represents one inch.You can also type in UNITS in the command line and the same window should appear. PrecisionSets the number of decimal places or fractional size displayed for linear measurements.2. Drawing Limits In order to set up drawing limits, Go:Format menu: Drawing limits .You can also type limits in the command line. You will then have to type in 4 limits in (x, y) coordinates form.3. Grid In order to create a grid, either type in Grid followed by typing in spacing in your grid. Or you can click onSNAP on the bottom of the window and set up the grid there.

2 Introducing Tool Bars


45/52

2. Introducing Tool Bars

You can see there is a number of different tool bars on the screen.The main tool bar which is located under the Menu bar. These are the most frequently used toolbars. If you place your mouse on it and right click, you will get a list of other tool bars that you maywant to display (by scrolling down and clicking on them).

This tool bar offersdifferent shapes

and objects todraw. You cansee what they doby putting yourmouse on each oneand waiting until

a balloon withdescription pops up.

This tool bar offers

different ways of

editing your drawing(s).*Remember the name of the command thatpops up in the help balloon by putting yourmouse over each button.If you remember the command, you can latertype it in the command line and achieve thesame result.

3. Where To Get Help

If you have any questions, you can always refer to AutoCAD Help. You can get there bytyping in Help in the command line or hitting F1. After the AutoCAD window opens up,select Search tab. Then you can type in a topic you would like to search for.


47/52

4. Layers and Layer Control

(from AutoCAD Help): You can reduce the visual complexity of a drawing and improve displayperformance by controlling the number of objects that are displayed or concealed. Forexample, you can use layers to control the visibility of similar objects, such as electrical partsor dimensions. Also, you can lock a layer to prevent objects on that layer from being

accidentally selected and modified.

Click here in order to create and modify layers.

5 Setting Up Line Weights


48/52

5. Setting Up Line WeightsThere are two ways to change Line Weights. One way is assign a line weight to a layer.Every line and object on that layer will then have the same line weight. The second wayto change line weight is by manually changing it one line at a time.

1) a. In order to assign line weight to a layer, click on Layer Properties Manager button.

b. Click here to change the line weight.

c. A box will pop up where you can assign line weights.

2) In order to change line weights one line at a time. Highlight the line on the screen and changeline weight by clicking on Line Weight Control button and scrolling down to pick thethickness.

6. Introduction to drawing using tool bars andcommands.

Remember there are a number of ways to draw in AutoCAD. One way is by opening upappropriate tool bars drawing using them. Another way is by typing in an appropriatecommand in the Command Line. You can also draw by looking up commands under the mainmenu on top of the screen. (Draw, Dimension, Modify.)

There are many drawing tools under Draw on the main menu and lots of modifying toolsunder Modify.Remember to use Help in order to find other commands you are not familiar with.

7. Drawing using OSNAP, POLAR, ORTHO, OTRACK


50/52

7. Drawing using OSNAP, POLAR, ORTHO, OTRACKbuttons.

On the bottom of the screen there are a number of buttons SNAP, GRID, ORTHO, POLAR,OSNAP,OTRACK, LWT, MODEL By right clicking on each button, you are able to change thesettings for each mode. By left-clicking on each button, you are able to turn each mode onand off.

SNAP- snaps onto grid points.GRID- turns on/off grid.

ORTHO- (from AutoCad Help) In Ortho mode, cursor movement is constrained to the horizontalor vertical directions (relative to the UCS) and with the current grid rotation angle. AutoCADignores Ortho mode in perspective views.

OSNAP- snaps onto parts of the object. You can change what your cursor snaps onto, ex:endpoints, crossings, corners

OTRACK- (from AutoCad Help) Use object snap tracking to track along alignment paths that arebased on object snap points.

LWT- displays the actual thickness of each line.MODEL- switches back and forth between layout space and model space.

8. Introduction to Layouts


51/52

y& Setting up Viewports

1).Layouts are used to create drawing sheetson which your drawings are plotted. In orderto create a layout, click on the layout tab(shown with an arrow above). Under PageSetup (located under File), you can pick theplotter, paper size, scale. Once your layout is

set up, you can create viewports in order toshow your drawing on the layout. In order tocreate a viewport: 1) Viewports under View(on the main menu) 2) pick how manyviewports you would like to create.

2). Once you have all the viewports inyour layout, you may scale them by:1. highlighting the box around eachviewport 2. right-clicking on the viewportand selecting properties 3. Underproperties click on Standard Scale.

Now, you are able to scroll down and picka scale for you viewport.

9. Plotting

After you set up your layout and are ready to print it, you may go to File and click on Plot. Ifyou have already picked your Plot Device and Plot Settings earlier under Page Setup, thenyoure probably ready to plot. If not, you should pick your Plot Device (printer) first (sincethat will change your paper options), and then set up your Plot Settings. Notice that you can print to different scales. Most of the time you will probably be printing1:1 scale, but you may print to other scales also.If you drew your drawings in units than you have an option letting the program know what 1unit equals (in terms of inches).You may also plot the whole layout, or just a window. If you would like to print part of thelayout, click on the window button and highlight everything you would like plot. Then hitfull preview before plotting your drawing.
