INTODUCTION Intoduction to CATIA V5R19 CATIA (Computer Aided Three-dimensional Interactive Application) is a multi-platform CAD/CAM/CAE commercial software suite developed by the French company Dassault Systemes and marketed worldwide by IBM. Written in the C++  programming language, CATIA is the cornerstone of the of  the Dassault ystemes  product lifecycle management software suite. T hrough its exceptionally Systemes product easy ± toto- use state of the of  the art user  interface, CATIA delivers inno vative technologies for maximum for  maximum producti  productivity and creativity, from concept to the final  bility of  using  product. CATIA reduces yhe learning cur ve ,as it allows the flexi b  based and parametric feature- b and  parametric designs .

CATIA  provides three basic  platforms: P1, P2, P3. P1 is for  small and medium sized  process oriented companies that wish to grow the large scale digitized  product definition. P2 is for  advanced design engineering companies that require  product,  process and resources modeling. P3 is for  high end design application and it is basically for  Automotive and Aerospace industry, where high quality surfacing or  Class-A surfacing is used for designing for  designing.

History :

CATIA started as an in-house development in 1977 by French aircraft manufacturer  Avions Marcel Dassault, at that time customer of  customer  of the the CADAM CAD software.

Initially named CATI (Conception Assistée Tridimensionnelle Interactive ² French for   Interactive Aided Three-dimensional Design ) ²  it was renamed CATIA in 1981, when Dassault created a su bsidiary to develop and sell the software, and signed a non-exclusive distri b  bution [2] agreement with IBM. In 1984, the Boeing Company chose CATI A as its main 3D CAD tool, becoming its largest customer . In 1988, CATIA version 3 was ported was  ported from mainframe computers to U NIX.

In 1990, General Dynamics E lectric Boat Corp chose CATIA as its main 3D CAD tool, to design the U.S.  Navy's Virginia class su bmarine. In 1992, CADAM was  purchased from IBM and the next year  CATIA CADAM V4 was  pu blished. In 1996, it was  ported from one to four  Unix operating systems, including IBM AIX, Silicon Graphics IR IX, Sun Microsystems SunOS and Hewlett-Packard HP-UX. In 1998, an entirely rewritten version of  CATIA, CATIA V5 was released, with support for  U NIX, Windows NT and Windows XP since 2001. In 2008, Dassault announced and released CATIA V6. While the ser ver  can run on Microsoft Windows, Linux or  AIX, client support for any operating system other than Microsoft Windows is dropped.

Industries using CATIA

CATIA is widely used throughout the engineering industry, especially in the automotive and aerospace sectors.  Aerospace

The Boeing Company used CATIA V3 to develop its 777 airliner, and is currently using CATIA V5 for the 787 series aircraft. They have employed the full range of  Dassault Systemes' 3D PLM  products ² CATIA, DELMIA, and E NOVI A LCA ² supplemented by Boeing developed applications. Chinese Xian JH-7A is the first aircraft developed by CATIA V5, when the design was completed on Septem ber  26, 2000. European aerospace giant Air  bus has been using CATIA since 2001. Canadian aircraft maker  Bom bardier  Aerospace has done all of  its aircraft design on CATIA. The Brazilian aircraft company, EMBRAER , use Catia V4 and V5 to build all airplanes. Vought Aircraft Industries use CATIA V4 and V5 to produce its parts. The British Helicopter company, Westlands, use CATIA V4 and V5 to produce all their aircraft. Westlands is now part of an Italian company called Finmeccanica the joined company calls themselves AgustaWestland.

The main supplier of helicopters to the U.S Military forces, Sikorsky Aircraft Corp., uses CATIA as well.  Automotive

Many automotive companies use CATIA to varying degrees, including BMW, Porsche, Daimler  AG, Chrysler, Audi,[11] Volkswagen, Bentley Motors Limited, Volvo, Fiat, Benteler  AG, PSA Peugeot Citroën, R enault, Toyota, Ford, Scania, Hyundai, koda Auto, Tesla Motors, Proton, Tata motors and Mahindra & Mahindra Limited, [[MLR  motors, Hydera bad][International cars & motors ltd(Sonalika group0,http://www.icml.co.in]. Goodyear  uses it in making tires for  automotive and aerospace and also uses a customized CATIA for  its design and development. Many automotive companies use CATIA for  car  structures ²  door  beams, IP supports, bumper   beams, roof  rails, side rails, body components ² because CATIA is very good in surface creation and Computer representation of surfaces. Shipbuilding

Dassault Systems has begun ser ving ship builders with CATIA V5 release 8, which includes special features useful to ship builders. GD Electric Boat used CATIA to design the latest fast attack  su bmarine class for  the United States  Navy, the V irginia class.  Northrop Grumman  Newport  News also used CATIA to design the Gerald R. Ford class of  supercarriers for  the US  Navy. Other

Architect Frank  Gehry has used the software, through the C-Cu bed Virtual Architecture company, now Virtual Build Team, to design his award-winning cur vilinear  buildings. His technology arm, Gehry Technologies, has been developing software based on CATIA V5 named Digital Pro ject. Digital Pro ject has been used to design buildings and has successfully completed a handful of  pro jects.

Solid Modeling 'Solid Modeling' is a method used to design  parts by com bining various 'solid o bjects' into a single three-dimensional (3D)  part design. Originally, solid modelers were based on solid o bjects  being formed by primitive shapes such as a cone, torus, cylinder, sphere, and so on. This evolved into solid o bjects being created and formed from swept, lofted, rotated, and extruded 2D wireframe or  sketch geometry.

Because of  their  limited use, some solid modelers have a bandoned the  primitive shapes altogether in favor  of  predefined li brary solid o bjects. 'Stock' li brary o bjects  pro vide the designer  with a similar  shape to begin the design with, eliminating some of the initial tedious design work .

The real  power  of  a solid modeling application is how it can take the solid o bjects and com bine them together  by intersecting, joining, or  su btracting the o bjects from one another  to create the desired resulting shapes. Because everything in a solid model design is a 'watertight' model of  the  part, the solid modeler  is a ble to know the topology of  the entire model. By topology we mean that it knows what faces are ad jacent to each other  and which edges are tangent.

Since the solid modeler's data base knows so much a bout the entire  part model, it can  perform functions virtually impossi ble with surface modeling. F or  example you can fillet all the ad jacent edges of  a face to other  faces in a single command. Another  popular  example is the 'shell' function of  solid modelers. This allows you to define a constant wall thickness for  the entire model with a simple task with a single command

constraints in solid modeling

Most solid modelers support 'geometric constraints'. A geometric constraint is the relationship of  an entity to other  entities. Constraints are only used on the underlying sketch or  wireframe entities that define the solid o bject bounaries. Some common 'constraints' for  these entities are coincident, collinear, intersect,  parallel,  perpendicular, and tangent . When one or  more entities are 'constrained' to each other, changing any of  the entities will most likely have an effect on the others. In the example , the lines and arcs have been assigned tangent constraints to each other  and two arc are mirror  to each other  . When one of  the arcs in the solid's boundary sketch is changed other one is also changed.

Some solid

modelers automatically assign the constraints for  you as you design the  part. O thers  provide the a bility to assign constraints as you are designing. CATIA will automatically assign constraints where it thinks you want them and then allow you to modify or  remove them manually later . In following example tangent constraint is automatically assign by CATIA

Single entity attri butes such as 'horizontal' and vertical' are also considered to be constraints, since tagging an entity with one of  these attri butes will keep the solid modeler  from changing it when other entities that have relationships to it are changed. Constraints are one of  the system basics needed to  provide true geometric associativity. Most solid modelers will allow you to add and modify constraints as needed. There are even some solid modelers that will attempt to automatically assign the required geometric constraints logically from the steps you take to design the part Solid modeling vs. Surface modeling:

For  designs that require any com bination of fillets along multiple edges, contain drafted surfaces, or constant wall thickness, solid modeling is far superior to surface modeling. For  designs that require sculptured surfaces with a lot of cur vature (the mouse you are using on you computer comes to mind) a surface modeler is far easier than a solid modeler . In fact it may  be virtually impossi ble to create some shapes with a solid modeler and hold exact dimensions for  very complex shapes.

BUTTERFLY VALVE ASSEMBLY:

A butterfly valve is a valve which can be used for  isolating or  regulating flow. The closing mechanism takes the form of  a disk . O peration is similar  to that of  a  ball valve, which allows for  quick  shut off . Butterfly valves are generally favored  because they are lower  in cost to other  valve designs as well as being lighter  in weight, meaning less support is required. A butterfly valve is from a family of  valves called quarter-turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off  the  passageway. W hen the valve is fully open, the disc is rotated a quarter  turn so that it allows an almost unrestricted  passage of the fluid. T he valve may also be opened incrementally to throttle flow.

Structure Butterfly valves are valves with a circular  body and a rotary motion disk  closure mem ber  which is  pivotally supported by its stem. A butterfly valve can appear  in various styles, including eccentric and high-performance valves. These are normally a type of  valve that uses a flat  plate to control the flow of  water . As well as this, butterfly valves are used on firefighting apparatus and typically are used on larger lines, such as front and rear suction ports and tank to  pump lines. A butterfly valve is also a type of  flow control device, used to make a fluid start or  stop flowing through a section of  pipe. The valve is similar  in operation to a ball valve. R otating the handle turns the plate either  parallel or  perpendicular to the flow of water, shutting off the flow.

Types 1. Resilient butterfly valve , having a flexi ble ru bber  seat. Working pressure 232  psi 2. High performance butterfly valve , usually dou ble eccentric in design. Working  pressure up to 725  psi 3. Tricentric butterfly valve , usually with metal seat design. Working pressure up to 1450  psi
