Autocad 2004

Autocad 2004
AutoCAD is a CAD(Computer Aided Design or Computer Aided Drafting) software application for 2D and 3D Designing and Drafting, developed and sold by Autodesk .inc Initially released in late 1982, AutoCAD was one of the first CAD programs to run on personal computers, and notably the IBM PC. Most CAD software at the time ran on graphics terminals connected to mainframe computers or mini-computers.
In earlier releases, AutoCAD used primitive entities — such as lines, polylines, circles, arcs, and text — as the foundation for more complex objects. Since the mid-1990s, AutoCAD has supported custom objects through its C++ API. Modern AutoCAD includes a full set of basic solid modeling and 3D tools. With the release of AutoCAD 2007 came improved 3D modeling functionality, which meant better navigation when working in 3D. Moreover, it became easier to edit 3D models. The mental ray engine was included in rendering, it was now possible to do quality renderings. AutoCAD 2010 introduced parametric functionality and mesh modeling.
AutoCAD supports a number of application programming interfaces (APIs) for customization and automation. These include AutoLISP, Visual LISP, VBA, .NET and ObjectARX. ObjectARX is a C++ class library, which was also the base for products extending AutoCAD functionality to specific fields, to create products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D, or third-party AutoCAD-based applications.

AutoCAD 2010

AUTOCAD 2010
Autocad 2010 is one of the most exciting releases in AutoCAD. It offers new features across the board, so that almost everyone will find something valuable.
AutoCAD 2010 has several new features as

Using GIS with HEC RAS

HEC-RAS has the ability to import three-dimensional river schematic and cross section data created in a GIS or CADD system.While the HEC RAS software only utilizes two dimensional data during the computations,the 3D information is used in the program for display purposes.After the user has completed a hydraulic analysisi,the computed water surface profiles can be exported back to the GIS or CADD system for development and display of a floodplain map.
The importing and exporting of GIS or CADD data is accomplished through the use of formatted ASCII text files,The text files provide a generic way of exchanging data between GIS/CADD systems and HEC -RAS,without adopting any single GIS/CADD system.
The HEC has developed a set of macros for Arc Info(using Arc Macro Language,AML) that will allow a user to write the geometric data in the required format as well as read the HEC-RAS results and perform the floodplain mapping.

National Geographic Megastructures

Sears Tower Megastructure Documentary Download
Willis Tower (formerly named, but still commonly referred to as, Sears Tower) is a 108-story, 1451-foot (442 m) skyscraper in Chicago, Illinois. At the time of its completion in 1974, it was the tallest building in the world, surpassing the World Trade Center towers in New York, and it held this rank for nearly 25 years. The Willis Tower is the tallest building in the United States and the fifth-tallest freestanding structure in the world, as well as the fifth tallest building in the world to the roof.

For 20 years, the Sears Tower held the record for the world’s tallest building. Completed in 1974, the 108 stories high building is almost half a kilometer tall. And it still holds the record for having the world’s highest antenna. John Zils, structural engineer and designer of this mega-structure shares some of the secrets about the tower. And get a behind-the-scenes look at some of the various systems and controls that are vital to the building, like security monitoring, the elevators, and the water and power distribution to the various levels, and even the machines that cleans the windows.

Although Sears' naming rights expired in 2003, the building continued to be called Sears Tower for several years. In March 2009 London-based insurance broker Willis Group Holdings, Ltd., agreed to lease a portion of the building and obtained the building's naming rights. On July 16, 2009, the building was officially renamed Willis Tower.

At 1,482.6 feet (451.9 m) tall, including decorative spires, the Petronas Twin Towers in Kuala Lumpur, Malaysia, laid claim to replacing the Sears Tower as the tallest building in the world in 1998. Not everyone agreed, and in the ensuing controversy four different categories of "tallest building" were created. Of these, Petronas was the tallest in one category (height to top of architectural elements, meaning spires but not antennas).

Channel Tunnel

The Channel Tunnel ( is a 50.5-kilometre (31.4 mi) undersea rail tunnel linking Folkestone, Kent in the United Kingdom with Coquelles, Pas-de-Calais near Calais in northern France beneath the English Channel at the Strait of Dover. At its lowest point, it is 75 metres (250 ft) deep.^[3]^[4]^[5] At 37.9 kilometres (23.5 mi), the Channel Tunnel possesses the longest undersea portion of any tunnel in the world, although the Seikan Tunnel in Japan is both longer overall at 53.85 kilometres (33.46 mi), and deeper at 240 metres (790 ft) below sea level. A tunnel connecting Britain and France has been an engineering holy grail since the early 19th century. The first attempt at a tunnel excavation began in 1880, but the project was abandoned soon after and workings lay dormant for a hundred years.

In 1988, international treaties were signed and once more excavation work began in earnest.

At 50km from Kent to Normandy, with a full 39km passing 40m under the English Channel seabed, the Channel Tunnel is the world’s longest marine subway.

Eleven tunnel boring machines, working from both sides of the Channel, cut through chalk marl to construct two railtunnels and a service tunnel. The vehicle shuttle terminals are at Cheriton (part of Folkestone) and Coquelles, and are connected to the British and French motorways (M20 and A16 respectively).

Tunnelling commenced in 1988 , and the tunnel began operating in 1994. In 1985 prices, the total construction cost was £4.650 billion (equivalent to £11 billion today), an 80% cost overrun. At the peak of construction 15,000 people were employed with daily expenditure over £3 million. Ten workers, eight of them British, were killed during construction between 1987 and 1993, most in the first few months of boring.

Fluid Mechanics

Dimensional Analysis
In engineering the application of fluid mechanics in designs make much of the use of empirical results from a lot of experiments. This data is often difficult to present in a readable form. Even from graphs it may be difficult to interpret. Dimensional analysis provides a strategy for choosing relevant data and how it should be presented.
This is a useful technique in all experimentally based areas of engineering. If it is possible to identify the factors involved in a physical situation, dimensional analysis can form a relationship between them. The resulting expressions may not at first sight appear rigorous but these qualitative results converted to quantitative forms can be used to obtain any unknown factors from experimental analysis.

Dimensions and units
Any physical situation can be described by certain familiar properties e.g. length, velocity, area, volume, acceleration etc. These are all known as dimensions. Of course dimensions are of no use without a magnitude being attached. We must know more than that something has a length. It must also have a standardised unit - such as a meter, a foot, a yard etc.Dimensions are properties which can be measured. Units are the standard elements we use to quantify these dimensions.
In dimensional analysis we are only concerned with the nature of the dimension i.e. its quality not its quantity. The following common abbreviation are used:

Hydraulics Modeling

A physical model is a scaled representation of a hydraulic flow situation. Both the
boundary conditions (e.g. channel bed, sidewalls), the upstream flow conditions
and the flow field must be scaled in an appropriate manner.
Physical hydraulic models are commonly used during design stages to optimize a
structure and to ensure a safe operation of the structure. They have an important
further role to assist non-engineering people during the `decision-making' process.
A hydraulic model may help the decision-makers to visualize and to picture the
flow field, before selecting a `suitable' design.
In civil engineering applications, a physical hydraulic model is usually a smaller-
size representation of the prototype (i.e. the full-scale structure) (e.g. Fig. 14.2).
Other applications of model studies (e.g. water treatment plant, flotation column)
may require the use of models larger than the prototype. In any case the model is
investigated in a laboratory under controlled conditions.
Hydraulic modeling cannot be disassociated from the basic theory of fluid
mechanics. To be eefficient and useful, experimental investigations require theoretical
guidance which derives primarily from the basic principles (see Chapter 13) and the
theory of similarity (see the next subsection).
In the present section, we will consider the physical modeling of hydraulic flows:
i.e. the use of laboratory models (with controlled flow conditions) to predict the
behavior of prototype flow situations.
In a physical model, the flow conditions are said to be similar to those in the prototype
if the model displays similarity of form (geometric similarity), similarity of motion
(kinematic similarity) and similarity of forces (dynamic similarity)...
