例

VBA:

Sub Example_HandleToObject()
    ' This example creates a spline in model space, and returns the
    ' handle for the spline. Then the spline is returned from the handle and colored.
    
    ' Create the spline
    Dim splineObj As AcadSpline
    Dim startTan(0 To 2) As Double
    Dim endTan(0 To 2) As Double
    Dim fitPoints(0 To 8) As Double
    
    startTan(0) = 0.5: startTan(1) = 0.5: startTan(2) = 0

    fitPoints(0) = 1: fitPoints(1) = 1: fitPoints(2) = 0
    fitPoints(3) = 5: fitPoints(4) = 5: fitPoints(5) = 0
    fitPoints(6) = 10: fitPoints(7) = 0: fitPoints(8) = 0
    Set splineObj = ThisDrawing.ModelSpace.AddSpline(fitPoints, startTan, endTan)
    
    ZoomAll
    
    ' Find the handle of the spline
    Dim handle As String
    handle = splineObj.handle
    MsgBox "The handle of the Spline is: " & splineObj.handle, , "HandleToObject Example"
        
    ' Find an object from a given handle
    Dim tempObj As AcadObject
    Set tempObj = ThisDrawing.HandleToObject(handle)

    ' Now use the newly initialized object variable to color the object 
    Dim color As AcadAcCmColor
    Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.20")
    Call color.SetRGB(80, 100, 244)
