Conventions Used in the Student Guide• Bold text within a sentence denotes options selected from the CATIA menu bar. • Red text denotes the name of a tool, icon, button, or window option. • Italic text within a sentence is used to apply emphasis on key words. • Numerical lists are used in sequential lists, such as the steps in a procedure. • Lower-case alphabetical sub-lists are used in sequential sub-lists, as for steps in an exercise procedure. • identifies areas in a picture that are associated with steps in a sequential list, such as in an exercise. • Upper-case alphabetical lists are used in non-sequential lists, as for a list of options or definitions. • Text enclosed in < > brackets represents the names of keyboard keys that must be pressed. • Text enclosed in [ ] brackets identifies text that must be entered into a text field of a CATIA dialog box or prompt.

Case Study: Introduction to Generative Shape DesignEach lesson in this course contains a case study, which helps to explain the skills and concepts covered in the lesson. You will be provided with different case studies at the end of each lesson helping you to practice and gain confidence. The focus of the case study in this lesson is to understand, how to access Surface Design workbench and to manage a few basic tools.

Design IntentEach case study contains a set of model requirements, known as the design intent. The first case study does not contain a design intent because you are not designing anything. However, by the end of this lesson you should be able to:

Open the given part consisting of the ??Air Craft?? model in the Generative Shape Design Workbench. Get familiar with the user interface.• Study the model along with the nomenclature given to different surfaces in the specification tree. Study the Surface, Wireframe and Operations.• Scan the model to understand the methodology and sequence of operations used to build the surfaces. Create separate containers for Surfaces, Wireframes and Operations for different parts of the Aircraft..• Create individual Geometrical Set for each part of the Aircraft. Under these Geometrical Sets, create sub-sets for separating the Wireframes, Operations and Surfaces (as shown in the Specification tree ). Finally Group the features from each Geometrical Set( which are often referred in the model ), thus minimizing the tree length.
