One way is to find a certain command on the tool bar or under one of the options on top of your window (File, Edi

3、t, 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 both ways.,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 Y

4、ou 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 drawing unit represents one inch. You can also type in “UNITS” in the command line and the same win

5、dow should appear. Precision Sets 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) c

6、oordinates 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 on SNAP on the bottom of the window and set up the grid there.,2. Introducing Tool BarsYou can see there is a number of different tool bars on the screen. The main t

7、ool bar which is located under the Menu bar. These are the most frequently used tool bars. If you place your mouse on it and right click, you will get a list of other tool bars that you may want to display (by scrolling down and clicking on them).,This tool bar offers different shapes and objects to

8、 draw. You can see what they do by putting your mouse on each one and waiting until a balloon with description pops up.,This tool bar offers different ways of editing your drawing(s). *Remember the name of the command that pops up in the help balloon by putting your mouse over each button. If you re

9、member the command, you can later type it in the command line and achieve the same result.,3. Where To Get Help,If you have any questions, you can always refer to AutoCAD Help”. You can get there by typing in “Help” in the command line or hitting F1. After the AutoCAD window opens up, select “Search

10、” tab. Then you can type in a topic you would like to search for.,4. Layers and Layer Control,(from AutoCAD Help): You can reduce the visual complexity of a drawing and improve display performance by controlling the number of objects that are displayed or concealed. For example, you can use layers t

11、o control the visibility of similar objects, such as electrical parts or 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,There are two ways to change Lin

12、e 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 way to 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 butto

13、n. 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 change line weight by clicking on Line Weight Control button and scrolling down to pick the thickness.,6. In

14、troduction to drawing using tool bars and commands.,Remember there are a number of ways to draw in AutoCAD. One way is by opening up appropriate tool bars drawing using them. Another way is by typing in an appropriate command in the Command Line. You can also draw by looking up commands under the ma

15、in menu on top of the screen. (Draw, Dimension, Modify.) There are many drawing tools under Draw on the main menu and lots of modifying tools under Modify. Remember to use Help in order to find other commands you are not familiar with.,7. Drawing using OSNAP, POLAR, ORTHO, OTRACK buttons.,On the bot

16、tom 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 the settings for each mode. By left-clicking on each button, you are able to turn each mode on and off. SNAP- snaps onto grid points. GRID- turn

17、s on/off grid. ORTHO- (from AutoCad Help) In Ortho mode, cursor movement is constrained to the horizontal or vertical directions (relative to the UCS) and with the current grid rotation angle. AutoCAD ignores Ortho mode in perspective views. OSNAP- snaps onto parts of the object. You can change what

18、 your cursor snaps onto, ex: endpoints, crossings, corners OTRACK- (from AutoCad Help) Use object snap tracking to track along alignment paths that are based on object snap points. LWT- displays the actual thickness of each line. MODEL- switches back and forth between layout space and model space.,8

19、. Introduction to Layouts& Setting up Viewports,1).Layouts are used to create drawing sheets on which your drawings are plotted. In order to create a layout, click on the layout tab (shown with an arrow above). Under Page Setup (located under File), you can pick the plotter, paper size, scale. Once

20、your layout is set up, you can create viewports in order to show your drawing on the layout. In order to create a viewport: 1) Viewports under View (on the main menu) 2) pick how many viewports you would like to create.,2). Once you have all the viewports in your layout, you may scale them by: 1. hi

21、ghlighting the box around each viewport 2. right-clicking on the viewport and selecting properties 3. Under properties click on Standard Scale. Now, you are able to scroll down and pick a 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. If you have already picked your Plot Device and Plot Settings earlier under Page Setup, then youre
