在 CATIA 中利用 VBA 读取 EXCEL 中的数据 '本程序可以把 EXCEL 表格中按一定格式存储的点、线、面等数据读取到 CATIA 并创建相应的对象'点数据是基本数据，线由点组成，面又由线组成，因此只有填写了点数据后才能添加线数据，'面与线类似本程序中默认的扩展数据为关键点处的内力数据，其 ID 应该与点数据的 ID 一致'下表中具体含义：ID—数据编号，（X，Y，Z）—点数据坐标值，（P1 ，P2）—组成线的点ID，'（L1 ， L2）—组成面的线 ID，（M，N，Q）—关键点处弯矩、轴力、剪力的数值'程序界面如下： '注意：表格中的数据区可以为空，每一类数据中只要有一行中出现空值，即认为该' 类数据结束，其后的数据不再读取本程序启动一次读入一张表格后，其点、线、面' 数据不应该被改变但其内力（M，N，Q）的数值允许改变，保存表格后，可以选择更' 新内力图（如果程序窗口已经关闭，重新启动后不要选中“创建点” 后重新打开文件）' 但一定要保证 CATIA 中该表格数据所在的几何图形集名称与表格对应，通常默认即可。
' 如果数据表中的点、线、面数据有变，即认为这是一张新的数据表，应该换一个新的文' 件名并作为新的数据表重新导入，若不改名则请确保当前 PART 根结点下没有与其文件名' 相同的几何图形集（此处几何图形集的命名方式为：DATA FORM EXCEL - 文件名）' 另外，内力关键点必须在同一平面内，且不在同一直线上'默认的 EXCLE 表格中数据格式如下：'表格可以扩展，具体格式也可能改变，此时须改变下列常数的值，以保证与表格中的一致'程序中使用的有关常数定义：Const Data_Start_Row = 3Const Point_ID_Col = 1Const Point_X_Col = 2Const Point_Y_Col = 3Const Point_Z_Col = 4Const Line_ID_Col = 6Const Line_Point1_Col = 7Const Line_Point2_Col = 8Const Mesh_ID_Col = 10Const Mesh_Line1_Col = 11Const Mesh_Line2_Col = 12Const Force_ID_Col = 14Const Force_M_Col = 15Const Force_N_Col = 16Const Force_Q_Col = 17Dim EXCEL As Object'*************************************Private Sub CreatePoint_CheckBox_Change()CreateLine_CheckBox.Value = CreatePoint_CheckBox.ValueCreateLine_CheckBox.Enabled = CreatePoint_CheckBox.ValueEnd SubPrivate Sub CreateLine_CheckBox_Change()CreateMesh_CheckBox.Value = CreateLine_CheckBox.ValueCreateMesh_CheckBox.Enabled = CreateLine_CheckBox.ValueEnd SubPrivate Sub ChooseFile_CommandButton_Click()On Error GoTo error_1Set EXCEL = CreateObject("EXCEL.Application", "")Dim DataFileName As StringDataFileName = EXCEL.GetOpenFilename("EXCEL Files (*.xls), *.xls")If DataFileName "False" ThenEXCEL.workbooks.Open DataFileNameMainForm_UserForm.ChooseFile_CommandButton.Caption = DataFileNameIf CreatePoint_CheckBox.Value = True ThenDim Cur_hybridBody As HybridBodySet Cur_hybridBody = Set_Cur_HybridBody()CreatePoint Cur_hybridBodyIf CreateLine_CheckBox.Value = True ThenCreateLine Cur_hybridBodyIf CreateMesh_CheckBox.Value = True ThenCreateMesh Cur_hybridBodyEnd IfEnd IfMainForm_UserForm.CreateForce_M_CommandButton.Enabled = TrueMainForm_UserForm.CreateForce_N_CommandButton.Enabled = TrueMainForm_UserForm.CreateForce_Q_CommandButton.Enabled = TrueEnd IfEnd IfExit Suberror_1:EXCEL.QuitEnd SubPrivate Function Set_Cur_HybridBody() As HybridBodyOn Error GoTo error_1Dim partDocument1 As PartDocumentSet partDocument1 = CATIA.ActiveDocumentDim part1 As PartSet part1 = partDocument1.PartDim hybridShapeFactory1 As HybridShapeFactorySet hybridShapeFactory1 = part1.HybridShapeFactoryDim hybridBodies1 As HybridBodiesSet hybridBodies1 = part1.HybridBodiesDim hybridBody1 As HybridBodyDim temp_name As Stringtemp_name = MainForm_UserForm.ChooseFile_CommandButton.Captiontemp_name = StrConv(Mid(temp_name, InStrRev(temp_name, "\") + 1), 1)k = 0For N = 1 To hybridBodies1.CountSet hybridBody1 = hybridBodies1.Item(N)If (Left(hybridBody1.Name, Len("DATA FROM EXCEL - " + temp_name)) = "DATA FROM EXCEL - " + temp_name) Thenk = k + 1End IfNext NIf k > 0 Then'MsgBox "have same data file!"hybridBody1.Name = "DATA FROM EXCEL - " + temp_name + "(" + CStr(k) + ")"End IfSet hybridBody1 = hybridBodies1.Add()hybridBody1.Name = "DATA FROM EXCEL - " + temp_nameSet Set_Cur_HybridBody = hybridBody1'Max = 1'For n = 1 To hybridBodies1.Count' Set hybridBody1 = hybridBodies1.Item(n)' If (Left(hybridBody1.Name, InStrRev(hybridBody1.Name, ".")) = "DATA FROM EXCEL.")
