PERINTAH CIRCLE UNTUK MENGGAMBAR LINGKARAN oleh Dian pramesti
Circle on AUTO CAD commands can be used to draw a circle in various ways. This command gives the option and each option gives the prompt on the placement of the center point. Common form of this command is
1. Pull - down menu: Draw - circle - circle, radius
2. Pull - down menu: Draw - circle - circle, diameter
3. Pull - down menu: Draw - circle - circle, 2 points
4. Pull - down menu: Draw - circle - circle, 3 points
5. Pull - down menu: Draw - circle - circle, tan tan radius
6. Pull - down menu: Draw - circle - circle, tan tan tan
How to draw a circle on Auto CAD is a circle by typing the command in the command window or by clicking on the icon circle
Command: _circle Specify center point for circle or [3P/2P/Ttr (tan tan radius)]:
Place the center point of the circle
Specify radius of circle or [Diameter]: select the diameter or radius (the radius of the circle)
Example command to create a circle with a radius of 100 units
Then the command is
Command: _circle Specify center point for circle or [3P/2P/Ttr (tan tan radius)]:
Place the center point of the circle
Specify radius of circle or [Diameter]: select radius (the radius of the circle) by typing the number 100

DETERMINING THE BROAD AREA OF FIGURES by Budi Maryanto, ST
Before we are using AUTO CAD drawing, then we must first determine the extent of the image area. It is intended that all objects drawn images can be seen all the picture area. At AUTO CAD by default, wide image area is 9 X 12 units.
Units used by AUTO CAD is a unit, 1 unit can be expressed as 1 meter, 1 inch or 1 millimeter, and so on. It is, depending on the users, when we have been accustomed to using the unit of measure in millimeters, then we can state that the unit is one millimeter.
For example:The area of the image that will be used is 420 X 297
To set the image area used in AUTO CAD commands limits.
How to use it is:
1. At the command prompt: type in LIMITS press enter
2. At the command prompt On / Off / <lower left corner> <0.000,0.000>: press enter
3. At the command prompt Upper right corner <12.000,9.000>: type hit enter 420.297.
drawings, models limits on AUTO CAD 2007
explanation
On numbers <12.000,9.000> is the square footage area of the image by default on AUTO CAD, while the number 420.297 is the area on the image that we specify AUTO CAD. Writing on the two figures separated by a comma (,) without spaces. Now we have to have a piece of paper as a working area for drawing a length of 420 units and 297 units where the width of the unit is 1 millimeter. However, the work area is not active, use the following command to activate the zoom
4. At the command prompt: type in the zoom press enter
5. At the command prompt All / center / dynamic .... : Type All press enter
Although not seen any changes on the screen, use the work to which we have been actively

MAKE A STRAIGHT LINE WITH POLAR ANGLE coordinates By Budi Maryanto.ST
One of the most fundamental of drawing Mechanical Engineering is making a line, in addition to making figures for the size, etiquette and writing a column for signs of other image processing.
To be able to create a line with coordinates to polar angle in AUTO CAD, we must understand the formula in polar coordinates angle formula AUTO CAD.Untuk make a line with coordinates to polar angle in AUTO CAD and begin with an @ sign to separate between the length of the line with the desired coordinates of the polar angle using the <.
The formula is
@ Length line <coordinates polar angle
To be able to use the formula in AUTO CAD polar angle is:
1. Click with the mouse icon image line, or line type using the keyboard command board
2. Place on work area AUTO CAD, then left click on the mouse or press enter
3. Input value size and value of the polar angle coordinate on board the command by typing on the
keyboard
iconic images of line
Example
If we want to draw a rectangle with a length of 40 and width of 20, then we type the commands to draw a box using the polar angle is:
1. @ 40 <0/360 hit enter: by typing this command, AUTO CAD will make
straight line from left to right with a length of 40
2. @ 20 <90 press enter: by typing this command, AUTO CAD will make
straight line up to size 20 at the end of the line
first
3. @ 40 <180 press enter: with this command, AUTO CAD will make a straight line
from right to left with a 40 at the end of the line
to two
4. @ 20 <270 press enter: by typing this command, AUTO CAD will make
straight line down to the size of 20 by the end of the line
to three

HISTORY OF CAD SYSTEM By BUDI Maryanto, ST
The first demonstration of the computer as a means of making an image done in MASSACHUSETTS INSTITUTE OF TECHNOLOGY, in 1963 by Dr. Ivan Sutherland, his system at the time was "Sketchpad" by using a cathode ray tube and light pen for input (input) image komputer.Suatu to an earlier system called SAGE, has been developed in the 1950s by the United States Air Defense Command by using a light pen to enter data. CAD systems are used for commercial purposes the first time in 1964 by the International Business Machines (IBM)
Many changes have occurred since the first demonstration conducted by Dr. Ivan Sutherland. The changes caused by the advent of microprocessors, software (programs) are more sophisticated and new applications in the industry. By using the CAD system many cases experienced by planners in conjunction with creating, improving image, obtaining prints (hard copy) and save the images with relative ease by using a fairly small space. CAD was originally used to help create production drawings. Advent of three-dimensional CAD software gives the fact that the 3-D computer model can help not only in manufacturing but also objects, along with a 3-dimensional database.
Picture Support, in the form of 3-dimensional
CAD can be connected either directly or via LOCAL AREA NETWORK (LAN) equipment to manufacture production, or in other words, CAD terminal equipment can be connected to the Numerical Control (NC) for memprogam NC machines automatically in product manufacturing operations.
