LIST OF BASIC SKILLS CAD By; Budi Maryanto, ST

    CAD software offers capabilities - basic skills, which are needed to produce the image documents. Here are some of the things the author, which became the basis of the ability of CAD.

1. Ability to Draw construction lines in each room that fits through any point, at any angle and produces
    a straight line, tangent to one or more arches
2. The ability to draw any type of line, such lines appear, central line, an invisible line or the line of pieces
3. The ability to draw circles and arches using a variety of sizes, with the size of the specified data entry.
4. The ability to make a cross on the line within the limits specified
5. The ability to create a scale or set a new scale in a variety of objects in images from a document
6. Ability to count or make a list of data with appropriate graphical construction, such as the distance of
    an object image, or the corners with precision.
7. The ability to produce a collection of elements forms the basis for publishing or copying images
8. The ability to move elements of the image to each new position. Repair or replace the extras in a saved
    document
9. The ability to examine all or remove portions lines, curved lines or any form of the basic elements of
      an image. Fixing dimensions
10. The ability to create a shadow glass or produce symmetrical forms
11. The ability to provide a composite measure or base unit
12. The ability to create an image with a record label and making the title box and a list of materials
13. The ability to store all images or parts of images to use in other documents and in other formats.
14. The ability to create three-dimensional images of the projected image in three directions
15. The ability to generate orthografis projection of a three-dimensional model of the image
16. The ability to take and use images that have been saved.

         However, the software programmers (software) is fixed and increase the ability of the software (software) CAD.Misalnya, many new program offering three-dimensional capabilities with highly sophisticated, on the operating system window.

       Hopefully this can be useful for anyone, who wants to install a CAD system, with respect to the basis of the ability-Traffic CAD system

SETTING THE NEED FOR CAD SYSTEMS By BUDI M, ST

     Which should be considered in the selection process is the CAD system is needed to determine whether CAD systems. Prospective users of CAD systems that have the potential for use should confer to determine how, when, where, how many CAD systems that will be used and whether the CAD system will work effectively and efficiently in terms of cost and operation.

example CAD systems, is Auto Cad 200

      Do not buy a system just because it thinks the first step towards the future by projecting an image forward. It is essential to investigate and make cost savings of CAD systems maker by contacting the CAD system users in its operations. Contact as many of the users of CAD systems, especially for those who experienced extensive. Prepare a short list of questions regarding the CAD system on cost, length of practice, the operating system, then check the answers to your questions and compare with your specific requirements. This information will determine the needs for your CAD system

     No doubt, you will hear a lot of statements about the productivity of the CAD system. Productivity CAD system however will depend on the technical operations. The first company to introduce and use a CAD system is the maker of electronic equipment. They get the experts in the field of equipment electronic images always draw a lot of symbols and also hardware standards using certain symbols. It is much less effective and efficient in drawing. A lot of time is wasted, because drawing all things that have been drawn. You can be sure that the CAD system will save 50 percent of the time making the picture than the use of the system biasa.Perlu note that only CAD system requires drawing once, although at the outset may take a long time rather than drawing on the drawing board. But after that, you just need to call the information in the data storage, and the system will do the CAD drawing with a very high speed. In this section a very clear advantage CAD system.

CHOOSING A CAD SYSTEM by Dian Pramesti

     Due to the number of manufacturing computer equipment continues to increase, then there is a cost reduction in the use of CAD systems. Some existing CAD systems may only traits needed to draw and produce two-dimensional objects, while for the other systems have the ability to produce three-dimensional pictures of objects. The CAD system makers always want to improve new functions or a CAD system which has undergone improvements that may not be in get on other systems. Almost every day the computer industry announced progress in the development of CAD systems.
Because of the new CAD system is generally much easier to operate, the words "user friendly" is often used by the CAD system makers to promote their systems, and there is a tendency to exaggerate the results of a particular CAD system.
       A prospective user must review the statement of program makers CAD system to the existing doubts in his heart proved, the fault of the program you select a CAD system can be misleading and disappointing and will add to the cost of the company. Unfortunately a lot of companies who already bought a CAD system to get CAD system is that it does not work as well as the company expected
Before buying a CAD system, a careful planning must consider this carefully. The plan is divided into five stages
1. Arrange the need for CAD systems
2. Investigate and select traits yamg CAD system in accordance with the requirements
3. Ask the CAD system demonstration
4. Revisit and rethink the CAD system chosen
5. Select, purchase, and install CAD system

Computer Engineering Structures

A. Not Just A Tool 

Which means that the computer is a tool that counters the first

developed for the fields of science and engineering. Only now has

growing increasingly distant, not only counters, but also writers,

painter, and entertainers with video and sound governance, as well as others.

Associated with construction or structural engineering, or rather structural

Computer engineering is the main task of the counter as

The initial purpose tools created, that of the origin of the word to compute.

However, in contrast with a previous count, the computer turns

change the mindset of the workings of engineers in performing structural analysis.

If the previous tradition, in order to understand the behavior of structures with

true, it must understand the methods of calculation manual

done, but with the availability of computers for analysis of the structure, then

without knowing the methods used, engineers can easily and

quickly obtain the desired results. In addition, various structural models

can easily be made, including the necessary mathematical manipulations.

Even so, there is no guarantee that it all makes

engineers can understand the behavior of the actual structure due to the

need to 

(a) understand the basic assumptions of the analysis, 

(b) understand the behavior of the structuretrue; 

(c) able to model the structure and validation results.

To the field of computer engineering is a very useful tool, for

competent users, it can produce a deeper understanding

about the field of engineering problems, in which traditional techniques

previously unable or difficult to get.

B. Basic Principles of Structural Modeling

Modeling the structure of data is numerical (mathematical) represent

real structure is used as input computer data. MacLeod (1990)

should propose the structure modeling are:

1. Do not be too complicated than necessary. If the model can be made

simple but representative, then generally it will be useful.

2. In relation to the above, in modeling sometimes need some

stages of the model. There is a whole (macro model) and other

in certain parts of the course but more detail (micro-models). Do not

willing to make the overall model accuracy

same for every desired detail 

3. Is simple model but still representative, it is necessary to know

behavior of the real structure. What factors are primary, secondary or

can be ignored. There is no guarantee that a lot of factors, the results

the better (lower bound theorem). Example, if the calculated bending deformation

the truss structure (truss), the trunk needs to size

are more likely to withstand axial and bending at the same time (more wasteful).

4. Do not immediately believe the computer output, unless it has been

validation-validation conducted a careful and rigorous (a priori).

5. Although there has been a rigorous validation-validation, do not be too trusting

first. View the assumptions used in the modeling analysis,

whether it is logical and represents real structural conditions (alert).

Use of electronic computers

Use of electronic computer at this point has been completely understandable almost at every stage of engineering, science, commerce, and industry, computers. Computers have changed the accounting procedures and manufacture of products, as well as with the application of techniques. Use of computers into the manufacturing process of making a plan to make an example (prototype), production and marketing, at the present time almost all done with computerization.

The application of engineering in particular is an area that will continue to change as new theories and practices that are more sophisticated berkembang.Peralatan continuously developed and perfected constantly using a computer-based CAD.

CAD-based computer has become an indispensable tool because it is effective and efficient for solving problems in the planning problems of working drawings and pictures samples (prototypes).
New methods for analysis, plan development, creation of engineering drawings with AUTO CAD, engineering problem solving and the development of new concepts in science automation is one example of the effect of the implementation of computers and industrial engineering.

OBJECTS OF ART TO

DATA BASE SINGLE
term of art is the object, using a single CAD data base that is used to plan, create documents, analyze, create shapes. The term of art to objects sometimes used to describe the CAD data base, which is used for various purposes or for the overall purpose

MAKE A SKETCH OF FREEDOM
These ideas are beginning to plan on using a hand sketch on a drawing paper, which aims to bring creative ideas to rencana.Sangat important to do a sketch with hand done quickly without having to use the aid program AUTO CAD.Kemampuan use sketch is one of the best tools to assist in this process.

MODELS ARE GIVEN REASON
After menyeleseikan initial ideas. The best step is the development of design plans at this stage selanjutnya.Pada stage, an engineer will make an image in three dimensions (3D) using rough AUTO CAD program for parametric modeling. Parametric modeling using factor not fixed to impose a three-dimensional (3D). Using parametric models planners prepare preliminary sketches and then give the size and limitations picture images to create a model of a given sense. Then planners can change the dimensions and such restrictions while refining the plan so that the new model does not have to be created on any change of plans. The images of three-dimensional (3D) which is derived by AUTO CAD program can help planners to visualize plans

Prototyping QUICKLY
While finishing ideas about the plan, the engineers often work closely with the manufacture to determine the best way to build and install parts (part) that perlu.Setelah several cycles increased, analyzes and synthesize the best ideas, the images generated by AUTO CAD, ready to be produced. Working system that allows rapid prototyping parts quickly made directly from the model of three-dimensional (3D) generated by AUTO CAD, a mock or trial.
