在VBA (Visual Basic for Applications) 中,将Excel数据批量写入CAD模板文件通常需要一些步骤,包括读取Excel数据、处理数据结构并将其写入CAD图形。下面是一个简化版的示例代码,假设你已经有一个包含数据的工作表,并且每个数据行对应CAD图纸中的一个特征:
```vba
Sub WriteDataToCAD()
'声明变量
Dim ws As Worksheet
Dim dataRange As Range
Dim i As Long, j As Long
Dim acadApp As Object
Dim acadDoc As Object
Dim cadLayerName As String
Dim csvData() As Variant
'设置工作表和范围
Set ws = ThisWorkbook.Worksheets("Sheet1") '假设数据在Sheet1
dataRange = ws.Range("A2:B10") '这里假设数据从A2开始
'读取Excel数据到二维数组
ReDim csvData(1 To dataRange.Rows.Count, 1 To 2)
For i = 1 To dataRange.Rows.Count
csvData(i, 1) = dataRange.Cells(i, 1).Value
csvData(i, 2) = dataRange.Cells(i, 2).Value
Next i
'创建AutoCAD应用对象
Set acadApp = CreateObject("AutoCAD.Application")
acadApp.Visible = False '设置为后台运行
'假设已知cadLayerName为CAD图层名称
cadLayerName = "MyCadLayer"
'循环遍历数据,创建新文档并写入
For i = 1 To UBound(csvData, 1)
'打开新的CAD文档
Set acadDoc = acadApp.Documents.Add
'假设DrawLine函数可以画线并指定坐标和图层
DrawLine acadDoc, csvData(i, 1), csvData(i, 2), cadLayerName
'关闭文档,释放资源
acadDoc.Close acSaveChanges := False
Next i
'清理对象
acadApp.Quit
End Sub
Function DrawLine(acadDoc As Object, x1 As Double, y1 As Double, layerName As String)
'在这个函数里添加实际绘制线条的代码
'例如:
acadDoc.ActiveView.CenterOn(x1, y1)
acadDoc.Layers(layerName).Linetype = "DASHED" '设置线型
acadDoc.Line(x1, y1, x1 + 10, y1, , acadDoc.Layers(layerName)) '绘制一条线
End Function
