例子

VBA：

Sub Example_Angle()
    ' This example adds a line in model space and returns the angle of the new line
   
    Dim lineObj As AcadLine
    Dim startPoint(0 To 2) As Double, endPoint(0 To 2)  As Double
    
    ' Define the start and end points for the line
    startPoint(0) = 1: startPoint(1) = 1: startPoint(2) = 0
    endPoint(0) = 5: endPoint(1) = 5: endPoint(2) = 0
    
    ' Create the line in model space
    Set lineObj = ThisDrawing.ModelSpace.AddLine(startPoint, endPoint)

    ThisDrawing.Application.ZoomAll
    
    MsgBox "The angle of the new Line is: " & lineObj.angle
End Sub
