CATIA V5 Foundation Course An Introduction to the Assembly Design Workbench The Assembly Design Workbench is used to bring together Parts (CATParts) into an assembly, which is known as a CATProduct document and as such contains no geometry but links to CATParts CATProducts can also be made up of a mixture of smaller CATProducts and CATParts to form larger complex assemblies CATProducts can be used in Kinematic simulation, Stress Analysis, Fitting Simulation, etc The CATProduct structure is represented by the Specification Tree, which holds details of all sub-assembles and their associated parts together with their relative positions to each other To maintain the position of the sub-assemblies and parts within the CATProduct, Assembly Constraints are used which are attached to the Specification Tree under a Constraints Node Kinematic Mechanisms, Fitting Simulations, etc are also attached to the tree under an Applications Node Top level Assembly Node Sub-Assemblies Graphical representation of the Assembly Sub-Assembly Parts Assembly Constraints DMS42177 ANS-UG0300108 Page of 71 Issue Truy cập Website: cadcenter.vn để Download tài liệu xem Video học CAD CAM CNC AIRBUS UK CATIA V5 Foundation Course Accessing the Assembly Design Workbench The Assembly Design Workbench can be accessed by either Selecting Start > Mechanical Design > Assembly Design from the Start drop down menu If a CATProduct is not active you will be prompted to create a new product by the appearance of the Part Name panel DMS42177 ANS-UG0300108 Page of 71 Issue Truy cập Website: cadcenter.vn để Download tài liệu xem Video học CAD CAM CNC AIRBUS UK CATIA V5 Foundation Course An overview of the different Specification Tree Nodes There are a variety of different node types displayed in the CATProduct Specification Tree as well as the ones contain within a CATPart Specification Tree, below are the three commonly used nodes: - A Product – this node links to a CATProduct document and can be used to position and orientate it within another CATProduct Yon can attach other nodes such as Product, Parts and Component to it A Part – contains a link to a CATPart document and used to position and orientates the part within the CATProduct You can not attach other nodes to a Part node A Component – this node contains no links to external documents and can be thought of as a dummy node You can position/orientate this node and attach other nodes to it such as Products and Parts Here is an example of a CATProduct with three Part nodes attached and a Component node with a single Part node attached to it Product Node Component Node Part Nodes Again the Specification Tree can be expanded or collapsed by selecting the ‘+’ or ‘-‘ symbol on the tree branch You can also use the View>Tree Expansion drop down menu DMS42177 ANS-UG0300108 Page of 71 Issue Truy cập Website: cadcenter.vn để Download tài liệu xem Video học CAD CAM CNC AIRBUS UK CATIA V5 Foundation Course Different Display Modes when using CATProducts There are two types of display modes available when viewing CATProducts: Visualisation Mode - This uses a Catia Graphical Representation or CGR format to create a visualisation of the CATParts within the Product Only the external appearance of the component is visualised The main advantage of using this mode is that performance of the workstation is improved by virtue of the fact that only a small amount of data is loaded into memory on the Workstation compared to using Design Mode This is especially true on large Assemblies The main disadvantages when Parts are in Visualisation mode are that you can not apply Assembly Constraints to them, modify any geometry or display the Parts Specification Tree When you open an existing CATProduct you are automatically placed into Visualisation mode, the CGR files are extracted from the CATPart documents that are attached to the Product and placed in a Cache directory on the Workstation Below is the Specification Tree for a Product when it is in Visualisation mode Note that that Assembly Constraints have yellow exclamation symbols attached to them which indicate that the link to the relevant Features have been broken This is normal and the link should reconnect when you switch to Design Mode In Visualisation mode there is no means of expanding the Parts node to view the Part Specification Tree DMS42177 ANS-UG0300108 Page of 71 Issue Truy cập Website: cadcenter.vn để Download tài liệu xem Video học CAD CAM CNC AIRBUS UK CATIA V5 Foundation Course The other mode is called Design Mode which allows gain access to the Part Specification Tree to edit Geometry, you can also apply constraints between Features on different Parts As mention prevoiusly when you open an existing Product you are automatically placed in Visualisation mode One way to enter Design mode is to select the top or root Node of the CATProduct and then use MB3 to access the contextual menu and then select the Representations tab followed by the Design Mode option All the CATParts attached to the Product Specification tree will now be loaded into Design Mode This also has the effect of loading the CATPart documents into the Workstations memory and on a large Assembly there may be a time delay whilst this task is performed Once in Design mode the CATPart Specification Trees are accessible by selecting the ‘+’ symbol next to the Part node The yellow exclamation symbol on the Constraints should now have disappeared indicating that they have successfully re-linked You also specify which Parts are loaded into Design mode by selecting them individually on the Specification Tree and then use MB3 to load them This may be a more preferable method when large Assemblies are concerned DMS42177 ANS-UG0300108 Page of 71 Issue Truy cập Website: cadcenter.vn để Download tài liệu xem Video học CAD CAM CNC AIRBUS UK CATIA V5 Foundation Course Another way to load a Product into Design mode is to select the Update All icon on the button menu bar When you first open an existing Product this icon will be yellow if you are in Visualisation mode and by selecting it all the Parts on the Specification will be loaded into Design mode and any links will be updated The Update All Icon Update Required No Update Required To switch back to Visualisation mode by using MB3 > Representations >Visualisation Mode Note: When you add a New Part to the Specification Tree it will be automatically loaded in Design mode DMS42177 ANS-UG0300108 Page 10 of 71 Issue Truy cập Website: cadcenter.vn để
