They are useful for creating assembly drawings and designing with the assembly in various states.,Scenes can control:,- Hide state of components,- Color of Components,- Position of components,- Activation of representations,Scenes are stored in an assemblys CATProduct file,Use Scene icon to create scene from the current state of the Assembly,When a scene already exists in the CATProduct , you can:- Copy and Paste it using Assembly Design Workbench - Edit it directly from Assembly Design Workbench by double clicking on it,Editing Scenes,6,Copyright DASSAULT SYSTEMES 2002,It can be useful to design while having the assembly in various states. Scenes can be used to capture and restore the state of components in an assembly.,Here the assembly is set to the state as defined by the “Shaft Scene”,Here the assembly is restored to its original state as defined by the “Complete Scene”,List of components that will change when applying the scene,Applying Scenes to an Assembly,7,Copyright DASSAULT SYSTEMES 2002,Only selected node of the Scene and its child components will appear in the view.,Creating a Drafting View Based on a Scene,Scenes make it possible to have drafting views where components are in different states than the assembly.,8,Copyright DASSAULT SYSTEMES 2002,New components are automatically added to Scenes, but they are inactivated,Deleted components are automatically removed from Scenes,Moved components are automatically moved in Scenes if they were not repositioned in the Scene,Before,After,Synchronizing Scenes,In some cases Scenes are automatically synchronized with changes to an assembly. In other cases, manual intervention is required.,9,Copyright DASSAULT SYSTEMES 2002,Deleted Scenes are removed from the assemblys CATProduct file,Keep in mind that deleting a Scene will effect drafting views that reference the Scene,Scenes can simply be deleted by selection of them and press on key,Deleting a Scene,Deleting a Scene removes the Scene from the assemblys CATProduct file.,10,Copyright DASSAULT SYSTEMES 2002,You will learn how to generate Bill of Material and Assembly Listing Reports and how to make Product Structure Numbering,Bill of Material Reports,Assembly Listing Reports,Product Structure Numbering,Generating Reports,11,Copyright DASSAULT SYSTEMES 2002,Bill of Material Reports,BOM with the components of the active assembly,One BOM for each sub-assembly,Recap of leaf components from the active assembly and all sub-assemblies,Interesting property of the component,12,Copyright DASSAULT SYSTEMES 2002,Assembly Listing Reports,Hierarchy showing every component from the active assembly and all sub-assemblies,Specify properties to be displayed and their order,Interesting property of the component,13,Copyright DASSAULT SYSTEMES 2002,Created Number,Created Number appearing in a balloon,Product Structure Numbering,14,Copyright DASSAULT SYSTEMES 2002,Generating Annotations,You will learn how to generate three kind of annotations in 3D assemblies,Weld Planner Annotations,Text notes with leader,Flag Notes with Leader,15,Copyright DASSAULT SYSTEMES 2002,Weld Planner annotations,Weld Planner feature,3D views,16,Copyright DASSAULT SYSTEMES 2002,Text Annotations,Capability to attach a text to a geometric element of a component,Selection,FD & T View,Text,17,Copyright DASSAULT SYSTEMES 2002,Flag Note,Capability to attach an hyperlink to a geometric element of a component,FD & T View,Flag Note,18,Copyright DASSAULT SYSTEMES 2002,Positioning Components without Constraints,In this lesson you will learn how to position components in cases where it is not convenient to use constraints,Reasons for positioning components without constraints,Translating and Rotating using Snap,Translating and Rotating using the Compass,Positioning Components Using,SmartMove,19,Copyright DASSAULT SYSTEMES 2002,Reasons for Positioning Components without Constraints,Positioning Relative to Components outside the rigid Sub-Assembly,Positioning with Convenience,20,Copyright DASSAULT SYSTEMES 2002,Translating and Rotating using Snap,Snap components to be parallel if necessary,Snap elements into alignment,Orientation arrow,21,Copyright DASSAULT SYSTEMES 2002,Translating and Rotating using the Compass,absolute position and orientation,Translation tools,Rotation tools,22,Copyright DASSAULT SYSTEMES 2002,Positioning Components Using,SmartMove,23,Copyright DASSAULT SYSTEMES 2002,Working with Large Assemblies,You will learn how to work with large assemblies,Hiding Components,Deactivating Representations,Product Init,Using Visualization Mode,Differences between Modes,24,Copyright DASSAULT SYSTEMES 2002,Hiding Components,Hide/Show state is stored in CATProduct files so that the state is maintained when the assembly is opened.,The components icon is dimmed in the tree.,Here an assembly is hidden.,Here one instance of the Connector Shell is hidden or no-shown.,Hidden components are not visible in “show space” or in drafting views.,25,Copyright DASSAULT SYSTEMES 2002,Deactivating Representations,Here one instance of the Connector Shell is deactivated. More precisely, the geometric representation is deactivated.,Deactivated representations are not visible in “show space” or “no-show space”.,This symbol means the geometric representation is deactivated,26,Copyright DASSAULT SYSTEMES 2002,Loaded component,Loaded and hidden component,Product Init dialog Box,Product Init,Required setting,Unloaded component,27,Copyright DASSAULT SYSTEMES 2002,Using Visualization Mode,Part in Visualization Mode (no on the node to access the definition),Part in Design Mode,When parts and models are in Visualization Mode, just a subset of the data is loaded in memory. The remaining data is loaded when needed.,Required settings,28,Copyright DASSAULT SYSTEMES 2002,Differences between Modes,This table highlights some key reasons for using Visualization Mode, Deactivation, and Hide.,29,Copyright DASSAULT SYSTEMES 2002,Designing & Managing Contextual Parts,In this lesson you will learn how to design and manage contextual parts,Creating Contextual Parts,Sketch and Contextual Design,Knowledgeware,and Contextual Design,Editing Contextually-related Parts,Analyzing Contextual Parts,Isolating Contextual Parts,Saving Contextually-related Documents,Deleting Contextually-related Components,30,Copyright DASSAULT SYSTEMES 2002,Creating Contextual Parts,Contextual parts have geometry that is driven by other components,green gear (contextual part in its context),Brown Gear (contextual part out of its context),Linked copy of geometry,Required Setting,(1),This rounded edge and the hole are,contextually,concentric with the pin in the green component. The sketch of the rounded edge and hole are explicitly constrained to be concentric with the pin.,(2),This bottom face of the brown part,contextually,rests on the top face of the green component. The brown face was sketched on the green face.,(3),The width of the brown “rib” is,contextually,controlled by the edges of the “slot” in the green component. The sketch of the brown “rib” was projected from the edges of the “slot” ,31,Copyright DASSAULT SYSTEMES 2002,Sketch and Contextual Design,It can be much more useful to select same sketch to define two different parts than using projections of edges of one part to define the other .,32,Copyright DASSAULT SYSTEMES 2002,Knowledgeware,and Contextual Design,It can be interesting to have parameters of a part driven by parameters of another part of the assembly or by parameters of the assembly itself .,In this case, we would like this parameter concerning,FixtureCoverForKWE,component to be equal to ,this other parameter concerning Holder component,Linked copy of Parameter,33,Copyright DASSAULT SYSTEMES 2002,Editing Contextually-related Parts (1/2),With regard to editing parts, there are two notions to consider : editing contextual parts that have external references and are therefore driven, and editing parts that drive contextual parts.,You can edit contextual part: the original instance or another one.You can also edit it outside the context of the Assembly,You can edit driving part and then contextual Parts will have to be synchronized,34,Copyright DASSAULT SYSTEMES 2002,Editing Contextually-related Parts (2/2),When you modify driving Part, Contextual parts have to be synchronized,Manual Synchronization,Automatic,Synchronization,35,Copyright DASSAULT SYSTEMES 2002,Analyzing Contextual Parts,Dependencies,Parent/Children,36,Copyright DASSAULT SYSTEMES 2002,Isolating Contextual Parts,Whole Part,Individual Element,37,Copyright DASSAULT SYSTEMES 2002,Saving Contextually-related Documents,After saving a Component under another name you will need to save all documents that refers it.
