nhiều tài liệu miễn phí Cokhi.org Hoccokhi.vn AIRBUS UK CATIA V5 Foundation Course An Introduction to the Assembly Design Workbench rg 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 co k hi o 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 Sub-Assemblies sh ar ed by Top level Assembly Node DMS42177 ANS-UG0300108 Graphical representation of the Assembly Sub-Assembly Parts Assembly Constraints Page of 71 Issue
