The chord length is the straight- line distance from the start point of the arc to the endpoint of the arc. Start point You can enter negative values for the chord length to draw an arc in the opposite direction.

The locations of the start and end points are at 11 and Click: Start, End, Radius button from the Arc flyout 12 11 Specify start point of arc or [Center]: select point 11 New arc Specify end point of arc: select point 12 Specify radius of arc: New arc 14 13 Figure 2.

You will give it a try off to the side of the subdivision drawing and then erase or undo it, as it is not a part of the drawing. To draw an arc that is the continuation of an existing line, Click: Line button On your own, draw a line anywhere on your screen. Last endpoint drawn. Continue makes this the start point for Click: Continue from the Draw panel, Arc flyout the new arc The last point of the line becomes the first point for the arc.

The cursor Last arc drawn is in drag mode, and an arc appears from the end of the line. You are prompted for an endpoint. Then you Continue makes the last point the start of the new arc will continue an arc from the endpoint of that arc.

On your own, erase or undo the extra continued arcs and lines that you created. Using Arc at the Command Line Tip: After you draw an arc, To select the Arc command, you can also type the command alias, A, restarting the command and at the command prompt. When you start the Arc command this way, then pressing the space bar the default is the 3 Points option you used earlier.

If you want to use or [Enter] also engages the Continue option. You can use another option, you can type the command option letter at the prompt. You will then specify from the previously drawn arc the start, end, and angle of the arc by typing the command option at the or line. Try it both ways.

However, it may be hard to see because of the small size of the arc relative to the size of the screen and drawing. Using Zoom The Zoom commands change the size of the image on your display.

The Zoom flyout is on the ribbon View tab, Navigate panel Figure 2. If it does not already show you can use Show panels to turn it on. Right-click in the gray space at the left of the View tab Click: Show panels from the context menu, Click Navigate The Navigate panel now appears on the ribbon View tab Figure 2. Navigate Panel Figure 2. Click: Zoom In button Your drawing is enlarged to twice its previous size Figure 2. Click: Zoom Out button Your drawing should return to its original size on the screen.

Zooming Using Scale Factors You can also use scale factors to zoom when you click the Scale option of the Zoom command. Scale factor 1. Scale factor 0. Typing X after the scale factor makes the zoom scale relative to the previous view. For example, entering 2X causes the new view to be shown twice as big as the view established previously, as you saw when using Zoom In.

A scale factor of 0. Zoom Scale uses the current left corner or 0,0 coordinates as the base location for the zoom. Typing XP after the scale factor makes the new zoom scale relative to paper space. You will learn more about paper space in Tutorial 5. You will select the Zoom command by typing its alias at the command prompt.

Repeat the Zoom command. The area shown on the screen is twice as big as the drawing limits. Now, restore the original view. This lets you quickly enlarge the exact Tip: When typing transparent portion of the drawing that you are interested in. You will select this commands, use an apostrophe command using the Zoom flyout.

This means that you can select it during execution of another command. You will zoom in on the area shown in Figure 2.

Click: Zoom Previous button Your drawing is returned to its original size. Areas can be repeatedly zoomed, that is, you can zoom in on a zoomed area; in fact, you can continue to zoom until the portion shown on the display is ten trillion times the size of the original. Zoom Realtime An easy way to zoom your drawing to the desired size is to use the Zoom Realtime feature on the Standard toolbar.

Click: Zoom Realtime button Select an arbitrary point in the middle of your drawing and hold down the click button of your pointing device while dragging the cursor up and down.

When you move the cursor upward, you zoom in closer to the drawing; when you move the cursor downward, you zoom out farther from the drawing. Scrolling the middle mouse wheel acts similar to Zoom Realtime. It is quick to use this method at any time during commands. Zoom All Zoom All returns the drawing to its original size by displaying the draw- ing limits, or displaying the drawing extents all of the drawing objects , whichever is larger.

Select the Zoom All icon from the Zoom flyout. Click: Zoom All button The drawing should return to its original size, that is, as it was before you began the Zoom command. Experiment on your own with the other options of the Zoom command and read about them in the Help window. Try these out now. All or double-click the scroll wheel to show the full drawing. Roll the scroll wheel towards yourself. The view zooms out and appears smaller.

Double-click the scroll wheel. The drawing fills the screen. Click: Zoom Dynamic The view box appears on your screen, as shown in Figure 2. The box shows an X in the center, indicating it is in position mode. As you move your mouse around, the view box moves with your mouse movements. Position the view box at the location you desire and click the mouse. Now an arrow appears at the right edge of the box and as you move your mouse, the size of the box is enlarged or reduced as shown in Figure 2.

You return to the position mode, so that you can move the box again. When you are satisfied with the location of the box, right-click the mouse and select Enter. The area enclosed in the box fills the graphics window. Using Pan Realtime The Pan command lets you position the drawing view on the screen without changing the zoom factor. Unlike the Move command, which moves the objects in your drawing to different locations on the coor- dinate system, the Pan command does not change the location of the objects on the coordinate system.

Rather, your view of the coordinate system and the objects changes to a different location on the screen. Press and hold the scroll wheel and move your mouse. Doing this, you can drag your drawing around on the screen.

The draw- ing should move freely about the drawing area until you let go of the scroll wheel, at which point it will stop. You can also select to use the Pan command from the ribbon, Click: Pan button from the View tab, Navigate panel Press and hold the left mouse button to position the drawing on the screen. Press: [Esc] or [Enter] to exit the command Double-click the scroll wheel to Zoom to the drawing extents.

Your drawing should now fill the drawing window. Using Circle Options In Tutorial 1 you learned to use the Circle command by specifying a center point and a radius value.

You can also use the Circle command to draw circles by specifying any two points Circle 2 Point , any three points Circle 3 Point , or two tangent references and a radius Circle Tan Tan Radius. You will use the Endpoint object snap mode to make circles that line up exactly with the ends of the existing lot lines.

Right-click: Object Snap button from the status bar Click: Endpoint so it appears checked on the list The Endpoint and Node running mode object snaps are now turned on. When you see the AutoSnap marker appear on the endpoint of a line, the crosshairs will snap to the marker point.

If you see the Node marker, move the crosshairs until the endpoint you want is highlighted. Your screen should look like Figure 2. First, you will change the current layer and zoom in on points 1 and 2, shown in Figure 2. To position the area near the center of the drawing Specify first corner: click point 1 window, hold down the scroll Specify opposite corner: click point 2 wheel to use Pan.

The area should be enlarged on your screen, as shown in Figure 2. Click: Object Snap button to turn it off The Object Snap button should now appear unselected, meaning that all running mode object snaps are temporarily turned off.

You should do so because sometimes object snaps can interfere with the selection of points and the operation of certain commands. This will not work well unless other object snaps are turned off. Tangent line 1 Tangent line 2 Figure 2.

Then give the radius of the resulting circle. This method is frequently used in laying out road centerlines. It involves selecting the two straight sections of the road centerline to which the curve is tangent and then specifying the radius. You can select either line first. You can also use Circle Tangent, Tangent, Radius to draw a circle tangent to two circles.

You will try this next by drawing two circles off to the side of the drawing and then adding a circle that is tangent to both of them. Tip: If you get the message, On your own, draw two circles off to the side of your subdivision drawing. Circle does not exist, the radius Click: Tan, Tan, Radius from the Circle flyout you specified may be too small or too large to be tangent to Specify point on object for first tangent of circle: select one of the both lines.

A circle with a radius of is drawn tangent to both circles. Circle Tangent, Tangent, Tangent The Circle Tangent, Tangent, Tangent command lets you quickly define a circle that is tangent to three entities in the drawing.

Try it on your own by selecting the Tan, Tan, Tan button from the Circle flyout and then selecting three lot lines to draw a circle tangent to. Now erase the extra circles on your own. Using Ellipse The command options for specifying an ellipse can be selected from the Ellipse flyout on the Home tab Draw panel.

Next, you will practice using the Ellipse command by drawing some ellipses off to the side of the drawing. You will erase them when you are through. The ellipse has a major axis the longest distance between two points on the ellipse and a minor axis the shorter distance across 2 the ellipse.

The AutoCAD program determines which axis is major and which is minor by examining the distance between the first pair of 60 angle Major axis endpoints and comparing it to the distance specified by the third point. This meth- 2 od requires you to specify the angle of rotation instead of the endpoint of the second axis.

See Figure 2. This time at the command prompt, use the options to specify the rotation angle, as though tipping a circle.

Specify distance to other axis or [Rotation]: R [Enter] Specify rotation around major axis: 35 [Enter] On your own, erase the ellipses that you created.
