CATIA装配设计——Connector Assembly.doc

Connector Assembly In this exercise, you will assemble the different components making up the connector assembly and learn how to analyze an assembly. Step (1): Assembling Components Start a new CATProduct assembly with Start menu +Mechanical Design+ Assembly Design or File + New + Product. Watch out?: with the CATIA Companion, click on the exercise icon (load model)?: this will open a default empty Product. Then, select File + Open menu and click on the Cancel button in the File Selection box (This is a necessary step that will set the selection path for the rest of this exercise). Right-click on the default product in the specification tree and select Properties option in the contextual menu to get the Properties dialog box. Type “Assembly Connector” in the Part Number field located in the “Product” tab:The name is displayed in the specification tree: Let’s add the components that are ready (=already designed) in this assembly.Right-click on the blue Connector Assembly and select “Existing components…” under Components branch in the contextual menu (or use the icon or the menu Insert + Existing component…”) and in the folder ConnectorAssembly_MasterExercise, select CATASMConnector_Shell.CATPart Repeat the same procedure and select: CATASMConnector_Card_Assembly.CATProductUsing the [ctrl] key you could have selected and inserted both components at once.The part and the assembly, are added in the geometry and in the tree: Now let’s duplicate the shell for the bottom part of the connector assembly: Copy the Connector Shell  Paste it into Connector Assembly.The second instance of the connector shell is added in the tree and in the geometry. Hint: you do not see it in the geometry as it is at the exact same position as the first instance. Let’s give some more explicit names to the instances :In Properties of the first instance (i.e.: Connector Shell (Connector shell.1)) Key in Top Shell in the top “Instance name” field;  Repeat the procedure on t
