Hello everyone, I've encountered some issues at work. In the following piece of code, I'm trying to modify the properties of the sheet metal folder to the K factor. When I change "swSheetMetalFeatureData.KFactor = 0.8" to "swSheetMetalFeatureData.BendDeduction = 2.5/1000", the code reports an error and displays a runtime error: "438: The object does not support this attribute or method." Please tell me how to modify the code. Thank you all!

Sub Main()
   Dim swApplication As SldWorks.SldWorks       ' SOLIDWORKS应用程序对象
   Dim swModel As SldWorks.ModelDoc2            ' 当前活动文档对象
   Dim swFeature As SldWorks.Feature            ' 特征对象
   Dim swSheetMetalFeatureData As SldWorks.SheetMetalFeatureData  ' 钣金特征数据
   Dim swEdgeFlangeFeatureData As SldWorks.EdgeFlangeFeatureData  ' 边线法兰特征数据
   Dim swCustomBendAllowance As SldWorks.CustomBendAllowance      ' 自定义折弯余量对象

   ' 获取当前SOLIDWORKS应用和活动文档
   Set swApplication = Application.SldWorks
   Set swModel = swApplication.ActiveDoc
   
   ' 获取钣金文件夹特征并设置其K因子为0.5
   Set swFeature = swModel.FeatureManager.GetSheetMetalFolder.GetFeature
   Set swSheetMetalFeatureData = swFeature.GetDefinition
   swSheetMetalFeatureData.KFactor = 0.8  ' 设置K因子为0.5
   swFeature.ModifyDefinition swSheetMetalFeatureData, swModel, Nothing  ' 应用修改

End Sub
