Knowledge Based Engineering (KBE) is becoming a powerful tool to reduce the lead time in design activities of aircraft and automotive industries. In this thesis work, an application has been built using this recent technology to reduce the lead time in the conceptual design phase of an Intermediate Case which is a component in a jet engine. The objective is to create various mid-shell design configurations of the component in less time using Knowledge Fusion (KF), a KBE based object oriented programming language in Unigraphics. Later these design configurations can be used to find out the optimum load path for various load cases.
