(cid:57) Review the model creation steps. (cid:57) Modify the design using the Define in Work Object command. (cid:57) Organize the features of the model into various bodies and geometrical sets. 4 Hours Copyright DASSAULT SYSTEMES 7 CATIA V5 Mechanical Design Expert STUDENT GUIDE Case Study The case study for this lesson is the Hinge. Design Intent (cid:57) The Hinge is a molded part that is used in an assembly. (cid:57) The part is symmetrical. (cid:57) The holes are centered on the bearings. Stages in the Process 1. Review the User Interface. XY plane 2. Understanding importance of Parent/Child Relationships. 3. Organizing a Model. X-section of handle block Copyright DASSAULT SYSTEMES 8 CATIA V5 Mechanical Design Expert STUDENT GUIDE Review the User Interface CATIA is mechanical design software. It is a feature-based, parametric solid modeling design tool that takes advantage of the easy-to-learn Windows graphical user interface. You can create fully associative 3D solid models with or without constraints while utilizing automatic or user-defined relations to capture design intent. (cid:57) The Part Design workbench lets you build solid 3D geometry. From the Part Design workbench you can access the Sketcher workbench and create 2D profiles that will become 3D model. (cid:57) The Assembly Design workbench allows you to bring components together to create the final product. You can design parts in the assembly context and use methods of designing assemblies that will aid in concurrent engineering, such as Skeleton models and publishing elements. (cid:57) The Generative Shape Design workbench lets you create surface and wireframe geometry. The surface and wireframe geometry allows you to create more complex solid models and gives more control over the shape of a model. Copyright DASSAULT SYSTEMES 9 CATIA V5 Mechanical Design Expert STUDENT GUIDE Importance of Parent/Child Relationships (1/2) Design intent is a plan to construct solid model of a Top Reference Plane part, in order to convey its visual and functional 1 aspects. The way a solid model is built can affect many aspects, including its flexibility to changes, its stability during the change process, and the resource 2 requirements to compute a new result. Therefore, it is Bottom Reference Plane important to take the design intent into account to achieve an efficient solid model of the part. 3 The dependency between one feature and the other 4 is known as a parent/child relationship. Parent/Child Relationships are important in maintaining the design intent of the part. You should carefully consider choosing the best base feature, which parent/child relationships should exist, and what dimensions and feature order best reflect the planned design intent.
