SolidWorks 折弯动画宏代码：逐步演示折弯过程

在 SolidWorks 中编写一个折弯动画的宏代码，可以使用以下的 VBA 代码：\n\nvba\nOption Explicit\n\nSub BendAnimation()\n Dim swApp As SldWorks.SldWorks\n Dim swModel As SldWorks.ModelDoc2\n Dim swPart As SldWorks.PartDoc\n Dim swFeatMgr As SldWorks.FeatureManager\n Dim swBend As SldWorks.BendFeatureData\n Dim swSelMgr As SldWorks.SelectionMgr\n Dim swSelData As SldWorks.SelectData\n Dim swSheetMetal As SldWorks.SheetMetalFeatureData\n Dim swBendAngle As Double\n Dim swBendRadius As Double\n Dim swBendDirection As Boolean\n Dim i As Integer\n \n Set swApp = Application.SldWorks\n Set swModel = swApp.ActiveDoc\n Set swPart = swModel\n \n If Not swPart Is Nothing Then\n Set swFeatMgr = swModel.FeatureManager\n Set swSheetMetal = swPart.FeatureByName("Sheet-Metal1")\n \n If Not swSheetMetal Is Nothing Then\n swSheetMetal.EnableFeature = True\n swModel.EditRebuild3\n swPart.ClearSelection2 True\n \n Set swSelMgr = swModel.SelectionManager\n \n For i = 1 To swSheetMetal.BendCount\n Set swBend = swSheetMetal.GetBendFeatureData(i)\n swBendAngle = swBend.Angle\n swBendRadius = swBend.Radius\n swBendDirection = swBend.Direction\n \n swPart.ClearSelection2 True\n \n Set swSelData = swSelMgr.CreateSelectData\n swSelData.Mark = i\n \n swSelMgr.EnableContourSelection = False\n swSelMgr.EnablePreSelectHighlight = True\n swSelMgr.EnableContourSelection = True\n \n swSelMgr.SelectFeatureByMark(swSelData)\n \n swPart.EditUnsuppress2 swBend.Name\n \n If swBendDirection Then\n swBend.Angle = 180\n Else\n swBend.Angle = 0\n End If\n \n swBend.Radius = 0\n \n swModel.EditRebuild3\n \n DoEvents\n \n swPart.EditSuppress2 swBend.Name\n \n swBend.Angle = swBendAngle\n swBend.Radius = swBendRadius\n \n swModel.EditRebuild3\n Next i\n End If\n End If\nEnd Sub\n\n\n这段代码创建了一个名为"BendAnimation"的宏。在此宏中，我们首先获取当前打开的活动模型，并通过特征管理器获取零件文档。然后，我们检查是否存在 Sheet-Metal 特征，如果存在，则启用该特征，并清除选择集。\n\n接下来，我们循环遍历所有的折弯特征。我们获取每个折弯特征的角度、半径和方向，并创建选择数据以选择该折弯特征。然后，我们解压缩该折弯特征，并将其角度更改为 180 度或 0 度（根据方向）。我们将半径设置为 0，并重建模型以显示折弯动画。\n\n最后，我们抑制该折弯特征，并将其角度和半径恢复为原始值。我们再次重建模型以恢复原始状态。\n\n在 SolidWorks 中运行此宏代码后，将出现一个折弯动画效果，通过逐步更改折弯特征的角度来模拟折弯过程。
