多义线的Coordinates属性直接可以得到啊!
帮助中的例子-
Sub Example_Coordinates()
' This example creates a polyline. It then uses the Coordinates
' property to return all the coordinates in the polyline. It then
' resets one of the vertices using the Coordinates property.
Dim plineObj As AcadPolyline ' Create Polyline
Dim points(5) As Double
points(0) = 3: points(1) = 7: points(2) = 0
points(3) = 9: points(4) = 2: points(5) = 0
Set plineObj = ThisDrawing.ModelSpace.AddPolyline(points)
ThisDrawing.Regen True ' Return all the coordinates of the polyline
Dim retCoord As Variant
retCoord = plineObj.Coordinates ' Display current coordinates for the first vertex
MsgBox "The current coordinates of the second vertex are: " & points(3) & ", " & points(4) & ", " & points(5), vbInformation, "Coordinates Example" ' Modify the coordinate of the second vertex to (5,5,0). Note that in
' case of a lightweight Polyline, indices will be different because the points are 2D only.
points(3) = 5
points(4) = 5
points(5) = 0
plineObj.Coordinates = points ' Update display
ThisDrawing.Regen True MsgBox "The new coordinates have been set to " & points(3) & ", " & points(4) & ", " & points(5), vbInformation, "Coordinates Example"
