Below, you can see how much does it cost to APPLE to manufacture each part of iPhone :

• Screen module (27 dolars) and touch screen Epson (24.50 dolars)
• Digital radio receiver Infineon (15.25 dolars)
• Graphics display chip National Semiconductor (1.50 dolars)
• Bluetooth chip CSR (1.90 dolars)
• Wireless internet chip Marvell Technology Group (6 dolars)
• Flash memory and Dram chip Samsung Electronics (76.25 dolars)

Of course, not all of the part manufacturers of iPhone was announced by iSuppli Corporation from England, who made this survey. No official cost analysis results were taken from companies like  Wolfson Microelectronics, which manufactures audio or other companies like Intel, Skyworks . Including assumptions for all other parts, iPhone is guessed to cost 266 dolars to APPLE. And the market price of iPhone is 600 dolars. If you take into account the marketing costs and copyrights and other patent costs, it is not very expensive. It seem that APPLE did not exaggerate the prices too much to be able to enter the market.

AutoCAD 12 and higher versions

In this article I will make an introduction to EXTRUDE command and we will learn how to use it.

Modeling toolbox is a new feature in AutoCAD 2007. However, most of the tools that it includes already exist in previous versions of AutoCAD. EXTRUDE command is one of the most popular methods that is used for converting 2 dimensional entities into 3 dimensional solid entities.

Now let’s examine the command.

In this article, I will explain about the REVOLVE command, which was previously been described in “Creating cylindric solids with REVOLVE command” and “A solid modelling application: Gusket drawing” articles.

Fig.1 It is very simple to create this model.

Hello Daily AutoCAD readers, 

From now on, every saturday, we will post the most favorite article of the week once more. This weeks most favorite article was “AutoLISP.2: Programming with Visual LISP editor”.

AutoCAD 2007 and higher versions

Hello Daily AutoCAD readers,

POLYSOLID is probably one of the most useful tools for creating 3D solid entities. It is available since AutoCAD 2007. By using this command, you can draw solid entities that are in forms of polylines that has constant width and height very fast, just like using the POLYLINE command. The most useful way of using POLYSOLID command is drawing a 3D wall.

Hello Daily AutoCAD readers,

In the third article of our series of articles about solid modeling, I explained about UNION and SUBTRACT and gave an example. And in this article, I will explain more about positioning the solid entities that make up the solid.

Hello Daily AutoCAD readers,

In this article of series of articles about 3D modeling, I will try to explain about UNION and SUBTRACT commands by an example that uses only a BOX solid. Our goal is to obtain the solid entity that is shown in Fig. 1. Read the rest of this entry »

Autocad 2007 and higher versions

Hello Daily AutoCAD readers,

In the second article of my series of articles about 3D modeling, I will explain about the primitive solid entities. In Fig. 1, you can see all of these entities together. Instead of explaining how each entity is drawn in AutoCAD, I will give you some figures that show the physical structure and what are the variables that AutoCAD needs to draw these entities.

AutoCAD 2007 and higher versions

Hello Daily AutoCAD readers,

I have been thinking about preparing a series of articles about 3D modeling for a very long time. I was busy with my daughter Ela and work, so I could finally start this series. In this series of articles, my goal is to explain about the concepts of 3D modeling starting from zero by giving examples, and besides to be able to teach you about the logic of working in 3D. So, stay tuned, a series of 15-20 articles are on the way.

In this first article of 3D modeling, I will introduce you with your working environment and teach you how to prepare you own environment.  By this way, you will have learned about the fundamentals of the concepts of VPOINT, VIEW, DASHBOARD and PROJECTION. Read the rest of this entry »

AutoCAD 2002 and higher versions

AutoDESK introduced plot style tables with AutoCAD 2002. It is very simple, it is a table that determines which layer is plotted how.

In old days, when we used to make drawing on tracing paper by using rapido, we used to use 0.2, 0.5 and 1 mm rapido thicknesses. By the time when we started drawing by using computer, there used to be plotters that have different sizes of pens in them. These plotters used to have a cartridge that is composed of 8 pens. A different number is assigned to each of the pen spaces in cartridge. What you have to do is simple to determine which of the colors in layer table will be plotted by using which number of pen. This is the most primitive form of the plot style table that was used in the beginning. Using different pen thicknesses for different colors is still a valid principle. In addition to this, idea of using different named plot styles arises. Read the rest of this entry »
