Examples

VBA:

Sub Example_ObjectIDToObject()
    ' 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 endTan(0 To 2) As Double

    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
    
    Dim objectID As Long
    objectID = splineObj.ObjectID

    ' Find an object from a given objectID
    Dim tempObj As AcadObject
    Set tempObj = ThisDrawing.ObjectIdToObject(objectID)

    ' Now use the newly initialized object variable to color the object
    Dim color As AcadAcCmColor
    Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor." & Left(CStr(AcadApplication.Version), 2))
