What is Catia ? CATIA (Computer Aided Three‐dimensional Interactive Application) is a multi‐platform CAD/CAM/CAE commercial software marketed worldwide by IBM. CAD/CAM/CAE commercial software marketed worldwide by IBM.
• Feature Based Modelingg • Advanced solid modeling techniques • Creating Engineering Drawings and Detailing Creating Engineering Dra ings and Detailing
Why Catia? •It has complete numeriacal control could define surfaces utlizing descriptive geometrical mathematical formulas that could be applied. •Catia model is invaluable in helping to fabricate complex forms quickly and accurately. •Addresses the complete product development process, from product concept specifications through product‐in‐service, in a fully integrated and associative manner.

Digital Project Integration
Digital Project started as an application used internally in Gehry Partners. DP is built on the CATIA Dassault platform and tailored to architectural design. DP now is an architectural design BIM tool commercially distributed by Gehry Technologies. Technologies CATIA already has been adopted by other engineering disciplines such as aerospace and automobile industries. There are many advance characteristics of deploying CATIA system, which include: 1) Full parametric definition User can define and parameterize variables at the detail geometry level as well as parametric relationship among objects and geometry sets. 2) Capable to handle complex shapes 2) Capable to handle complex shapes CATIA and Digital Project are famous for their capability to handle complex and parametric geometry (e.g. NURBS surfaces). It has been greatly used to leverage the fluid‐dynamic in aircraft, shipbuilding and automobile design. 3) Alternative storage method CATIA d Di it l P j t CATIA and Digital Project can store data as either a Part or Product file. A complex assembly can hold enormous t d t ith P t P d t fil A l bl h ld amount of parts or products. Existing part and product files can also be referenced from other files to increase the reusability of designed parts. Its file manager can handle a large amount of parts and products together for complex assemblies. 4) Interoperable with Subsystems DP can produce information for many subsystems and not only preliminary objects from the architectural design. As a BIM application it can produce structure, MEP and other manufacturing documents along with the design.
