以下是使用VB编写的计算SolidWorks工程图图幅的示例函数:
```vb
Imports SolidWorks.Interop.sldworks
Imports SolidWorks.Interop.swconst
Public Class SolidWorksHelper
Public Function CalculateDrawingScale(width As Double, height As Double) As String
Dim swApp As SldWorks = Nothing
Dim swModel As ModelDoc2 = Nothing
Dim swDraw As DrawingDoc = Nothing
Dim swSheet As Sheet = Nothing
Try
' 创建SolidWorks应用程序对象
swApp = CreateObject("SldWorks.Application")
swApp.Visible = False
' 打开工程图文件
swModel = swApp.OpenDoc6("path_to_drawing_file", swDocumentTypes_e.swDocDRAWING, swOpenDocOptions_e.swOpenDocOptions_Silent, "", 0, 0)
' 转换为DrawingDoc对象
swDraw = DirectCast(swModel, DrawingDoc)
' 获取第一个图纸页
swSheet = swDraw.GetCurrentSheet()
' 获取图纸页的比例尺
Dim scale As Double = swSheet.Scale2
' 计算图幅
Dim drawingWidth As Double = width / scale
Dim drawingHeight As Double = height / scale
' 返回图幅结果
Return "图幅:" & drawingWidth & "mm x " & drawingHeight & "mm"
Catch ex As Exception
Return "错误:" & ex.Message
Finally
' 释放资源
If Not IsNothing(swSheet) Then Marshal.ReleaseComObject(swSheet)
If Not IsNothing(swDraw) Then Marshal.ReleaseComObject(swDraw)
If Not IsNothing(swModel) Then swModel.Close()
If Not IsNothing(swApp) Then swApp.ExitApp()
End Try
End Function
End Class
```
请注意,这只是一个示例函数,您需要根据您的具体需求进行适当的修改和调整。在使用此函数之前,请确保已安装SolidWorks软件,并将"SolidWorks.Interop.sldworks"和"SolidWorks.Interop.swconst"添加到项目的引用中。
此函数接受工程图的宽度和高度作为参数,并返回计算后的图幅结果。您需要将"path_to_drawing_file"替换为实际的工程图文件路径。
希望这能帮助到您!如有其他问题,请随时提问。
