如何在裝配體中選中壓縮文件

醉风

rt，嘗試了instance.extension.selectall以及
    assemblyFile = "C:\Program Files\SolidWorks Corp\SolidWorks\samples\introsw\bolt-assembly.sldasm"
    Set swModel = swApp.OpenDoc6(assemblyFile, swDocASSEMBLY, swOpenDocOptions_Silent, "", errors, warnings)
    Set swModelDocExt = swModel.Extension
    Set swSelMgr = swModel.SelectionManager
    'Select all components in assembly
    SelectAllinDocument
都沒法選中壓縮文件，求指教。。。
