Design Structures 設計結構
The Save command creates design structures in Agile , to hold the CAD files , It is important to understand how these structures are set up in Agile . CAD designs consist mainly of these types of files - Parts , Assemblies , and Drawings . In terms of the design structure hierarchy , Parts are the lowest level . They are combined into parent Assemblies ,which in turn are combined into higher-level Assemblies . Drawings are represented at a higher level than either Parts or Assemblies; essentially a Drawing is a "parent" of whatever assembly or part that is on the drawing.
保存命令在Agile中創建設計結構，處理CAD文件。理解在Agile 中這些結構是如何創建的是非常重要的。CAD設計主要包括三種文件-零件，裝配體，工程圖，在設計的結構層中，零件是最低級別的。它們組成父裝配體（組件），進而組成更高級別的裝配體。工程圖時比零件和裝配體更高的一個結構層次。在工程圖中工程圖時零件或者裝配體的父節點。
The figure below illustrates a case of a Pro/Engineer five-part assembly, where each of the parts, and also the assembly, has corresponding drawings. The assembly (D00007) is the parent of all the parts, and each drawing is the parent of its respective assembly or part . It s important to keep this structure in mind when using EC operations like Save and Load , and also when browsing through design structure data in Agile.
下圖展示了一個用Pro/Engineer 做的 五個零件的裝配體的案例。每個零件，裝配體都有對應的工程圖。裝配體是每個零件的雙親，每個工程圖時每個裝配體或者零件的雙親。保持這個結構是重要的，在使用EC操作的時候，比如保存和加載，以及在Agile中瀏覽設計結構數據時。
For example , since the Save and Load commands work on a single structure at a time, you can save drawing D0008 and it will save assembly D00007 and the five parts, but not the five part drawings (because they are not in the same tree structure- you would not see then within the BOM tab of D00008 in Agile) . For this situation you can use the Save session command, which will include all files active in the CAD session within the Save dialog.
舉個例子,在保存或者加載命令工作在一個單獨結構的時候，可以保存工程圖D0008 並且它會保存裝配體D00007 以及五個零件，但是不會保存五個工程圖（因爲它們不在同一個樹結構下，你不會再Agile中的D00008的BOM標籤下看到它們）.這種情況下，可以使用保存會話命令，它會保存在CAD會話中所有激活的文件使用保存對話框。
Similar types of structures are used to store other specialty types of CAD files, such as Pro/E family table generics, and drawing format files. In each case, the Connector is set up to recognize the files as being stored in these particular type of structures, so they must not be manually modified in Agile or erros may result.
類似的結構類型被使用保存其他特定類型的CAD 文件，比如Pro/E 系列表創建，和工程圖格式文件。每種情況，連接器建立組織這些文件以他們特定的結構，所以他們一定不可以手動在Agile中編輯，否則會出現錯誤的結果。
