This article shows the application of Knowledge Based Engineering (KBE) methodology for the design automation of the structure of an automotive painting defects inspection tunnel. A previous work reached the design automation through the data transfering from Spreadsheets to Siemens NX CAD software using applications programmed with Visual Basic. With the application of KBE, it was possible to control the geometrical features of every part in the tunnel, to properly manage the component addition to the assembly and to reach a direct interaction between the designer and the CAD tunnel model in a new and more insightful manner. The presented work was developed through Knowledge Fusion (KF), a Siemens NX module which is based in Knowledge Based Engineering (KBE).

All Major mechanical CAD software products have provided application programming interfaces (APIs) and environments for users to develop customizations and plug-ins to meet their specific requirements. Automation of design methodologies and processes using the available APIs will result in improved productivity of the designers. Typically, during automation of designing a component, one algorithm for a particular shape of the component is implemented in automation programs. In this paper, an automation approach for solid construction using Completely Constrained Generic and Unitized sketches is discussed, that will enable us to implement one algorithm for a family of shapes. Both the types of sketches, i.e., Generic and Unitized sketches are completely constrained and parametric in nature. Generic sketches are those sketches that are constructed to result in more than one shape by making some minor modifications. The required modifications are explained in detail in this paper. These Generic sketches can be either closed or open. Unitized sketches are special cases of Generic sketches that are open. The Unitized sketches cannot be independently used for solid construction. A combination of these Unitized sketches in a sequence can result in a closed profile that can be used for solid constructions. The closed Generic sketches can be independently used for solid constructions. The change in shape of both types of sketches is with respect to the local reference system and the sketches can be positioned in 3d space by defining constraints with respect to the global reference system. This approach can be effectively used in design automation of components that has finite number of shape variations which are driven by design rules. These concepts have been demonstrated in the design of some aircraft structural components.

“…The biggest advantage of this type of modelling is reflected in the possibility of a rapid change in size, shape and position of the modelled elements [9][10][11]. Lack of parametric modelling is reflected in the need to invest more time and effort in the process of modelling elements, but the time and effort of multiple payments in phases of assembly designing must also be emphasized.…”

Integrated intelligent CAD systems (IICAD) can be developed for different purposes. The objective of this article is to emphasize the advantages of the use of IICAD systems in comparison with the classic systems. The article shows a structure of one such developed system, namely the IICADv system. This system is used for automatization of activities undertaken during the realization of certain phases of the process of designing of shafts, especially the synthesis phase. The development of a module for computation of the shaft and integration of the entire system was performed in the C# programming language, while shaping of the shaft was performed in the CATIA system. The interlinking was performed thanks to previously modelled basic 3D models. In such way, utilizing the advanced IICADv system, the computation and shaping of the shaft is done almost instantly. The results of the use of the IICADv systems are generated final 3D models of the shaft, ready for use by numerous other applications.
