例子

VBA：

Sub Example_GetWindowToPlot()
    ' This example allows the user to define an area in the current layout to plot
    ' and displays a plot preview of the defined area.
    '
    ' * Note: You will have to exit the plot preview
    '  before the VBA example will stop and control will be returned
    
    AppActivate ThisDrawing.Application.Caption
    
    Dim point1 As Variant, point2 As Variant
    
    ' Get first point in window
    point1 = ThisDrawing.Utility.GetPoint(, "Click the lower-left of the window to plot.")
    ReDim Preserve point1(0 To 1)   ' Change this to a 2D array by removing the Z position
    
    ' Get second point in window
    point2 = ThisDrawing.Utility.GetPoint(, "Click the upper-right of the window to plot.")
    ReDim Preserve point2(0 To 1)   ' Change this to a 2D array by removing the Z position
    
    ' Send information about window to current layout
    ThisDrawing.ActiveLayout.SetWindowToPlot point1, point2
    
    ' Read back window information
    ThisDrawing.ActiveLayout.GetWindowToPlot point1, point2
    
    MsgBox "Press any key to plot the following window:" & vbCrLf & vbCrLf & _
           "Lower Left: " & point1(0) & ", " & point1(1) & vbCrLf & _
           "Upper Right: " & point2(0) & ", " & point2(1)
    
    ' Make sure the instruction is to plot a view, not some other plot style
    ThisDrawing.ActiveLayout.PlotType = acWindow
    
    ' Send Plot To Window
    ThisDrawing.ActiveLayout.ConfigName = "DWG to PDF.pc3"
    ThisDrawing.Plot.DisplayPlotPreview acFullPreview
