Copyrighted Material Copyrighted Material 3. Set the Precision to two digits after the decimal point as shown in the above figure. Pick OK to exit the Drawing Units dialog box. It also serves as a visual reference that marks the working area. Note that this setting does not limit the region for geometry construction. Copyrighted Material 3. Copyrighted Material 4. On your own, move the graphic cursor near the upper-right comer inside the drawing area and note that the drawing area is unchanged.

The Drawing Limits command is used to set the drawing area; but the display will not be adjusted until a display command is used. In the pull-down menus, select: [View] [Zoom] [All] The Zoom All command will adjust the display so that all objects in the drawing are displayed to be as large as possible. If no objects are constructed, the Drawing Limits are used to adjust the current viewport. Move the graphic cursor near the upperright comer inside the drawing area and note that the display area is updated.

Copyrighted Material Using the Line Command 1. Copyrighted Material 2. Move the graphics cursor to the first icon in the Draw toolbar. This icon is the Line icon. Select the icon by clicking once with the left-mouse-button, which will activate the Line command. Notice a brief explanation of the selected command is displayed in the Info Palette window.

Click on Close button located at the upper left corner of the Info Palette window as shown. Copyrighted Material 6. The three numbers represent the location of the cursor in the X, Y, and Z directions. We can treat the graphics window as if it was a piece of paper and we are using the graphics cursor as if it were a pencil with which to draw. Copyrighted Material Coordinates of the location of the graphics cursor.

Do not be overly concerned with the actual size or the accuracy of your freehand sketch. We will start at a location near the bottom of the graphics window. Left-click once to position the starting point of our first line. This will be point 1 of our sketch.

The two numbers, displayed next to the cursor, represent the current cursor position. Note that the same two numbers are also displayed at the lower left corner of the AutoCAD main window. The displaying of tooltips is known as the Dynamic Input option. Tooltips are displayed near the cursor, which are dynamically updated as the cursor moves. Copyrighted Material 8.

Next move the cursor upward and toward the right side of point 1. Notice the rubber-band line that follows the graphics cursor in the graphics window. Left-click again point 2 and we have created the first line of our sketch. This feature is also part of the Dynamic Input option. A more detailed discussion on how to utilize this feature is presented in Chapter 3 of this text.

Copyrighted Material Move the cursor to the left of point 2 and create a horizontal line roughly about the same length as the first line on the screen.

Copyrighted Material 5 3 2 1 Repeat the above steps and complete the freehand sketch by adding three more lines from point 3 to point 4, point 4 to point 5, and then connect to point 5 back to point 1. Copyrighted Material 4 Notice that the Line command remains activated even after we connected the last segment of the line to the starting point point 1 of our sketch. Inside the graphics window, click once with the right-mouse-button and a popup menu appears on the screen.

Select Enter with the left-mouse-button to end the Line command. On your own, move the cursor near point 2 and point 3, and estimate the length of the horizontal line by watching the displayed coordinates for each point at the bottom of the screen. This method is perhaps the fastest way to specify locations on the screen. However, it is rather difficult to try to create a line of a specific length by watching the displayed coordinates.

It would be helpful to know what one inch or one meter looks like on the screen while we are creating entities. We will use the GRID and SNAP options to get a visual reference as to the size of objects and learn to restrict the movement of the cursor to a set increment on the screen. When the corresponding button is highlighted, the specific option is turned ON.

Using the buttons is a quick and easy way to make changes to these drawing aid options. We can toggle the options on and off in the middle of another command. Move the cursor inside the graphics window, and estimate the distance in between the grid points by watching the coordinates display at the bottom of the screen. Using the grid is similar to placing a sheet of grid paper under a drawing. The grid helps you align objects and visualize the distance between them.

The grid is not displayed in the plotted drawing. The default grid spacing, which means the distance in between two dots on the screen, is 0. We can see that the sketched horizontal line in the sketch is about 4. A more detailed discussion on this feature is presented in Chapter three. SNAP On 1. Move the cursor inside the graphics window, and move the cursor diagonally on the screen. Observe the movement of the cursor and watch the coordinates display at the bottom of the screen.

The SNAP option controls an invisible rectangular grid that restricts cursor movement to specified intervals. When SNAP mode is on, the screen cursor and all input coordinates are snapped to the nearest point on the grid. The default snap interval is 0. Click on the Line icon in the Draw toolbar. Copyrighted Material Copyrighted Material 5. Use the right-mouse-button and select Enter in the popup menu to end the Line command if you have not done so.

We will erase two of the lines using the Erase command. Rotate mouse wheel. ZOOM Command. All of the above. If AutoCAD is displaying length of a line as Display of length has nothing to do with precision. The default workspace in AutoCAD is. AutoCAD Classic. Right click and select PAN from contextual menu. PAN command. Press and hold middle mouse button. Introduction to AutoCAD. Part 2 — Basic draw commands. Which symbol can be used to specify angle for making an inclined line? AutoCAD circle flyout on draw panel offers how many ways to make a circle?

Which option will you use to make a circle which is tangent to a line and circle and has certain radius value. Tangent, tangent, radius circle. Tangent, tangent, tangent circle.

What is the command for starting rectangle. The shortcut for starting polyline command is. What is the maximum number of sides with which a polygon can be made in AutoCAD. There is no limitation on number of sides. In the image shown here, the polygon is inscribed or circumscribed about the green circle? Is it possible to make a rectangle with fillets on all four vertices? Can you use Polygon tool to make a polygon with a known edge length without using inscribed or circumscribed circle as a reference?

To make the arc as shown in the image here which Arc command can be most effectively used? Three Point Arc. Start End Radius. Center Start End. Center Start Length. Creating Drawing Quiz. Part 3 — Basic modify commands. State true or false: It is not possible to make a linear array with copy command. State true or false: An object is selected only if the crossing window or polygon completely encloses it.

In the image shown here, what is the offset distance between both the closed geometries? To reduce the size of an object to half of its initial value using SCALE command the scale factor would be? Fillet will be applied to all Polylines of the drawing. Fillet will be applied to all objects except Polylines. Fillet will be applied to all the vertices of selected Polyline.

As per the array command of AutoCAD, what is the row gap between rectangles in this array? Apabila digunakan untuk membuat garis yang bersegmen maka masing-masing garis pembentuk segmen tersebut merupakan objek tunggal. Antara satu dengan yang lainnya tidak ada kaitan. Garis bias dibuat dengan cara menentukan dua buah titik ujung. Untuk kumpulan garis bersegmen maka ujung dari garis sebelumya merupakan titik awal bagi garis selanjutnya.

Cara menggunakan perintah Line untuk membuat garis bisa dilakukan dengan cara sebagai berikut. Klik titik mulai pembuatan garis pada titik 1.

Tentukan panjang garis dengan klik langsung pada titik 2. Jika d. Anda ingin melanjutkan lagi, klik lagi pada titik 3. Tekan Enter untuk mengakhiri perintah. Gambar 2. Klik titik mulai pembuatan garis titik 1. Tekan Enter. Contoh aplikasi: misalnya Anda akan membuat garis dengan 0 d. MultyLine ML Multiline merupakan fasilitas untuk membuat garis ganda. Dalam penggambarannya kita bisa menentukan poisisi kursornya, jarak antargaris skala , serta jenis garisnya.

Secara default jarak antargaris Multiline adalah 1. Namun demikian, Anda bisa mengaturnya sesuai dengan kebutuhan penggambaran. Ketik 0. Klik titik 1 pada area gambar. Ketik C lalu tekan Enter untuk mengakhiri. PolyLine PL Pada prinsipnya Polyline juga merupakan perangkat untuk membuatgaris, tetapi objek yang dihasilkan dari polyline merupakan garis satukesatuan. Untuk memperjelas tentang fungsi dan kegunaan polyline dalam penggambaran, bisa dilihat tiga perbedaan fungsi antara Polyline dan Line yang tersedia pada AutoCAD.

Cara menggunakan Polyline untuk menggambar garis lurus yangdikombinasikan dengan garis lengkung bisa dilakukan dengan cara sebagai berikut. Buat garis lengkung dengan klik titik 2 kemudian titik 3. Klik pada titik 4. Polygon Polygon berfungsi untuk membuat objek segi banyak dengan sisi sama panjang. Jumlah sisi polygon yang bisa dibentuk minimal 3 sisi segitiga , sedangkan sisi maksimal yang bisa dibentuk adalah Polygon bisa dibuat dengan dua metode, yaitu Incribed in circle dan Circumsribed about circle.

Apabila Anda membuat polygon menggunakan metode Incribed in circle, berarti Anda membuat polygon dengan cara meletakkan polygon di dalam lingkaran bantu. Untuk metode Circumscribed about circle berarti Anda membuat polygon dengan cara Powered by: www. Lingkaran bantu tersebut sebenarnya tidak terlihat pada area gambar karena hanya digunakan untuk menentukan jenis pembuatan serta radius polygon selama proses penggambaran. Contoh metode aplikasi penggambaran polygon dengan pilihan Inscribed in circle adalah sebagai berikut.

Klik titik pusat polygon.
