Digital Project

Digital Project starts 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.
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
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 and Digital Project can store data as either a Part or Product file. A complex assembly can hold enormous 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.
