Learning AutoCAD or AutoCAD LT is a bit like trying to decide which came first — the chicken or the egg. On one hand, you need to know the basics before you can start drawing. On the other hand, understanding the basics can be very difficult if you haven't had the experience of drawing something. In this Quick Start chapter, you resolve this problem by drawing, dimensioning, and printing a simple window in AutoCAD or AutoCAD LT.
This Quick Start chapter is meant for beginners. You'll get the feel of AutoCAD's precision drawing tools and experience how to build a drawing. The AutoCAD/AutoCAD LT interface, including the toolbars and menus, is very customizable. Note that the instructions for the exercise in this chapter assume that no one has made major changes to the default settings.
Chapter 1 through 5 fill you in on basic information that you need to move on to drawings that are more complex. By experiencing the drawing process first, you will find the initial learning curve to be easier and smoother.
NOTE
Don't worry if you don't immediately understand everything you're doing. It all becomes clear as you progress through this book. If you haven't read the Preface, now is a good time to go back and read the part that explains how to follow the exercises. When you type the X and Y coordinates (shown in bold), type the first number, a comma, and then the second number, with no spaces between them. The symbol means to press Enter on your keyboard.
Choose File New. The Select Template dialog box opens. Navigate to the Drawings folder of the DVD of this book, choose abqs-a.dwt, and click Open. You see a blank drawing. (I explain more about templates and opening drawings in Chapter 2.)
To save the drawing and give it a name, choose File
Save. In the Save Drawing As dialog box, use the Save In drop-down list to navigate to any convenient folder, such as the My Documents folder. Type abqs-01 in the File Name text box and click Save. (I go into more detail about saving a drawing in Chapter 1.)
NOTE
In Chapter 1, I provide instructions for creating a special AutoCAD Bible folder for all the exercises in this book. If you want to create this folder now, do so and save the drawing in that folder.
To free up the drawing area, close any windows or palettes that are open, by clicking their Close (X) button, so that your screen looks like Figure QS-2.
On the right side of the screen, you should see a palette, called the Dashboard, which contains the Layers control panel (section), as shown in Figures QS-1 and QS-2. If not, see the Note instructions following this step. From the Layer Control drop-down list on the Dashboard, click the down arrow and choose WINDOW, as shown in Figure QS-1. (Layers help you organize the objects in your drawing; I cover them in detail in Chapter 11.) Anything you draw will now be on the WINDOW layer.
NOTE
If you don't see the Dashboard, choose Tools Palettes
Dashboard. If you still don't see the Dashboard, it may be minimized to a thin, vertical bar, usually on the right side of your screen. Place your cursor over the bar, and the Dashboard should appear. For easier use during this tutorial, right-click the part of the vertical bar closest to the rest of the Dashboard; if the Auto-Hide item is checked, click it to uncheck it so that the Dashboard stays open. If you don't see the Layers control panel shown in Figure QS-1, right-click anywhere on the Dashboard and choose Control Panels
Layers.
With your left mouse button (also called the pick button), choose Rectangle from the 2D Draw control panel of the Dashboard. The 2D Draw control panel should be above the Layers control panel that you used in the previous step. (Using the Dashboard is only one way to give AutoCAD and AutoCAD LT commands. I explain other ways in Chapter 3. You can find more about drawing lines and rectangles in Chapter 6.) Move your mouse so that the cursor is in the main drawing area. Your screen should look like Figure QS-2. (If you don't see the tooltip bar — also called the Dynamic Input tooltip — near the cursor, then click the DYN button on the status bar at the bottom of your screen.)
Follow these prompts to draw a rectangle that is 44″ wide and 80″ high.
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: 0,0Specify other corner point or [Area/Dimensions/Rotation]: 44,80
NOTE
You see the full prompt shown here in the Command window at the bottom of your screen. You see an abbreviated version of the same prompt in the Dynamic Input tooltip that appears near the mouse cursor. In an architectural drawing, distances are assumed to be in inches, so you don't need to specify a unit (although you can if you want).
Notice that the text that you type in appears next to the cursor in the Dynamic Input tooltip. When you press Enter, the text that you typed is echoed in the Command Line window at the bottom of the screen.
To create a second rectangle inside the first one, choose Offset from the 2D Draw control panel of the Dashboard, and follow these prompts:
Specify offset distance or [Through/Erase/Layer] <Through>: 4Select object to offset or [Exit/Undo] <Exit>: Click the rectangle's border to select it.
Specify point on side to offset or [Exit/Multiple/Undo] <Exit>: Click anywhere inside the rectangle. Select object to offset or [Exit/Undo] <Exit>:
You can draw from geometric points on objects such as endpoints and midpoints. (I explain how to specify coordinate points in Chapter 4.) To draw a line between the midpoints of the inner rectangle, choose Line from the 2D Draw control panel of the Dashboard and follow these prompts:
Specify first point: Press and hold the Shift key and right-click. From the shortcut menu that opens, choose Midpoint. Place the cursor near the midpoint of the left side of the inner rectangle. When you see a triangle and the Midpoint tooltip, click. Specify next point or [Undo]: Press and hold the Shift key and right- click. From the shortcut menu that opens, choose Midpoint. This time, place the cursor near the midpoint of the right side of the inner rectangle. When you see the Midpoint tooltip and triangle, click. Specify next point or [Undo]:
Your drawing should now look like Figure QS-3. (Your window should be green.)
You will now draw a temporary construction line to help you find a starting point for the pane in the top of the window. From the 2D Draw control panel of the Dashboard, choose Line. Follow these prompts:
Specify first point: Press Shift and right-click. Choose Endpoint from the shortcut menu. Pick the left endpoint of the last line you drew.
Specify next point or [Undo]: 4,4. (This notation specifies that the endpoint of the line is 4 units above and to the right of the first point. Chapter 4 explains more about specifying coordinates in this manner.) Specify next point or [Undo]:
Again, choose Rectangle from the 2D Draw control panel of the Dashboard. Follow these prompts:
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/ Width]: Press Shift and right-click. Choose Endpoint and pick the final endpoint of the diagonal line you just drew. Specify other corner point or [Area/Dimensions/Rotation]: 2'4",2'4"
NOTE
This notation specifies 2 feet, 4 inches in the X and Y directions.
Choose Erase from the 2D Draw control panel of the Dashboard. At the Select objects: prompt, click the short, diagonal construction line that you drew in Step 9. The Select objects: prompt appears again. Press Enter to end the command. (Chapter 9 explains the ERASE command as well as other simple editing commands.)
Click the ORTHO button on the status bar at the bottom of the drawing area if it is not already selected (indented). The ORTHO feature constrains drawing to right angles — either horizontal or vertical. (You can find more about ORTHO in Chapter 4.)
To finish the bottom of the window, choose Line from the 2D Draw control panel of the Dashboard. Follow these prompts:
Specify first point: 8",3'4"Specify next point or [Undo]: Move the mouse cursor down from the start point of the line. You see a temporary drag line. Then type the following length of the line. 2'8-7/16
NOTE
You can see what you type in the Dynamic Input tooltip as you are typing. Therefore, you can check that you've typed the right numbers before you press Enter.
Specify next point or [Undo]: Move the cursor horizontally to the right and type 28. Specify next point or [Close/Undo]: Now try entering the distance using decimal notation, instead of feet and inches. Move the cursor up and type 32.4375Specify next point or [Close/Undo]:
Choose Line from the 2D Draw control panel of the Dashboard. Follow the prompts:
Specify first point: Press Shift and right-click. Choose Endpoint from the shortcut menu. Click the upper-left corner of the window. Specify next point or [Undo]: Move the cursor to the left. Type 1'6"Specify next point or [Undo]: Move the cursor down. Type 6'8"Specify next point or [Close/Undo]: Type #0,0. (The pound sign ensures that your line goes to 0,0 no matter where you are.) Specify next point or [Close/Undo]:
To draw the opposite shutter, you'll mirror the first shutter that you just drew. (I cover the MIRROR command and many other editing commands in Chapter 10.) Choose Mirror from the 2D Draw control panel of the Dashboard and follow these prompts:
Select objects: Click the three lines that make up the shutter. Select objects:Specify first point of mirror line: Press Shift and right-click. Choose Midpoint from the shortcut menu. Click near the middle of the top horizontal line of the window. Specify second point of mirror line: (The ORTHO button should still be indented. If it isn't, click it.) Move the cursor downward and pick any point. Erase source objects? [Yes/No] <N>:
The window should look like Figure QS-4.
To add a dimension to the bottom of the window, you should first change the layer. From the Layer Control drop-down list on the Layers control panel of the Dashboard, choose DIMENSION. (Chapter 14 and 15 explain how to create and format all types of dimensions.)
To place the dimension, choose Dimension Linear from the menu. Follow the prompts.
Specify first extension line origin or <select object>:(Pressing Enter lets you select an object to dimension.) Select object to dimension: Pick the bottom horizontal line of the window (the bottom of the rectangle). Specify dimension line location or [Mtext/Text/Angle/Horizontal/Vertical/Rotated]: Move the cursor down until the dimension is nicely spaced below the window. Click to place the dimension line.
NOTE
If you don't have enough room to place the dimension below the window, click the down arrow of the vertical scrollbar as necessary. I explain additional techniques for changing the view of your drawing in Chapter 8.
Click Save on the Standard Annotation toolbar to save your work.
To prepare for printing, click the Layout tab, A Title Block-Landscape, at the bottom of the drawing area. If you don't see any tabs, click the A Title Block-Landscape button at the right end of the row of buttons on the status bar below the drawing area. You then see the window inside a title block and border, as shown in Figure QS-5. This title block and border come with the template to help you easily prepare the drawing for printing. (Chapter 17 explains how to lay out and print/plot a drawing.)
To set the scale for printing, click the magenta viewport border (labeled in Figure QS-5). Choose Tools Palettes
Properties. In the Properties palette, click the Standard Scale item. (To see this item, you may have to scroll down in the Properties palette or enlarge it by dragging on its bottom and right edges. If the palette collapses to a thin bar, pass your cursor over the bar to expand it.) Click the down arrow that appears to the right of this item and check that the scale is set to 1″ = 1′-0″. Click the Close button at the top of the Properties palette. (I explain more about scales in Chapter 5.)
If the window and its dimension are not centered in the viewport window, double-click inside the viewport border. Then choose View Pan
Realtime. Click and drag as necessary to center the window in the viewport. Press Esc to exit Pan mode. Double-click outside the viewport border to return to the layout.
To add some text to the title block, you need to zoom in. (I explain zooming in more detail in Chapter 8.) Choose View
Zoom
Window. Follow the prompts:
Specify first corner: Click slightly above and to the left of the words Project Name. Specify opposite corner: Click slightly below and to the right of the words City ST ZIP.
These words should now appear very large in the drawing area. They are already placed and formatted, so all you need to do is replace them. (I explain all about how to create and edit text in Chapter 13.)
Double-click the Project name text. The Text Formatting toolbar opens, along with a ruler, as shown in Figure QS-6.
Select the text by dragging from the upper-left corner to the lower-right corner. Type the following:
Double-hung window2010 Coral LaneAnytown, IA 12345
Click OK on the Text Formatting toolbar to close the In-Place Text Editor.
To return to your previous view, choose View
Zoom
Previous from the menu.
You're ready to print your drawing! Depending on your setup, either you can print directly to your printer, or if you have a plotter available, you can use that. (The layout is set up to fit on an 8@@bf1/2-x-11-inch or A-size paper.) Choose Plot on the Standard Annotation toolbar. The Plot dialog box opens. (I cover printing and plotting in Chapter 17. Appendix A explains how to configure a printer or plotter.)
In the Printer/plotter section of the Plot dialog box, click the Name drop-down list and choose the printer or plotter that you want to use.
Click the Preview button to open the preview window. You should see the window and its title block laid out as shown in Figure QS-7.
NOTE
If things don't seem right, click the Close Preview Window button and review the previous steps to see if you can find the problem. Also, see the sidebar, "Help! My Drawing Doesn't Look Like the Figure."
Make sure your printer or plotter has an 8'f1/2-x-11-inch or A-size sheet of paper, and click the Plot button on the Preview window's toolbar. Congratulations! You've just created and printed your first drawing!
Click the Close button at the upper-right corner of the AutoCAD application window to close both AutoCAD and the drawing. Click Yes to save your changes.
NOTE
It's important to understand that this Quick Start tutorial used techniques that are easiest to understand for beginners; as a result, the techniques were sometimes a little awkward. AutoCAD and AutoCAD LT have many capabilities that make drawing easier and faster. You learn all these features in this book.
In this exercise, you practiced many of the skills that you need to use AutoCAD or AutoCAD LT effectively. Most of your work in AutoCAD or AutoCAD LT builds on these basic skills. The rest of the chapters in this book explain these procedures in more detail as well as many features not covered in this Quick Start exercise.
