* * * * * * * * * * * * In some cases it may be necessary to position components in sub-assemblies relatively to components that are outside the sub-assembly. An example is described here. * * * * * * * * * * * * * * * * * * * * * * * * * * Bill of Material Reports list the components of assemblies. Components are listed by Part Number and the quantity of each Part Number is computed. * * Assembly Listing Reports list the components of assemblies. Components are listed in a hierarchical or tree format. * * The Generate Numbering command allows you to associate numbers or letters to the parts which make up your product. Those numbers will also appear when creating balloons on Drawings generated from the assembly The generated numbers also appear in the bill of Material * * Job aid * * 黄翔 教授 * * 装配实例3 Connector Assembly Objectives : In this exercise you will build the Connector Assembly and modify one of its components. In this Exercise you will use : Product Structure Tools Assembly Constraints Compass Clash Analysis Part Design in Context Standard Tools Connector_Assembly 黄翔 教授 * * Design Intent: Connector Assembly Create and name the assembly as “Connector Assembly”. Add a sub-assembly “Connector Card assembly” and two instances of “Connector Shell”. Assign instance names to the two instances of “Connector Shell”. Position each component and set constraints between them. Analyze for interferences between the components and correct the interference by making an opening for the “Connector Card Assembly”. Add two instances of “Screw”. 黄翔 教授 * * Design Process: Connector Assembly 黄翔 教授 * * Step 1: Assembling Components Create a new CATProduct and name it as “Connector Assembly” Insert existing components “CATASMConnector_Shell.CATPart” and “CATASMConnector_Card_Assembly.CATProduct” Duplicate the “CATASMConnector_Shell.CATPart” Copy the “Connector Shell” Paste it into “Connector Assembly” 黄翔 教授 * * Create a contact constraint between the inside face of the “Top Sh
