About Moving Objects Along a Vector (VBA/ActiveX)

You can move all drawing objects and attribute reference objects along a specified vector.

To move an object, use the Move method provided for that object. This method requires two coordinates as input. These coordinates define a displacement vector indicating how far the given object is to be moved and in what direction.

Move a circle along a vector

This example creates a circle and then moves that circle two units along the X axis.

Sub Ch4_MoveCircle()
  ' Create the circle
  Dim circleObj As AcadCircle
  Dim center(0 To 2) As Double
  Dim radius As Double
  center(0) = 2#: center(1) = 2#: center(2) = 0#
  radius = 0.5
  Set circleObj = ThisDrawing.ModelSpace.AddCircle(center, radius)
  ZoomAll

  ' Define the points that make up the move vector.
  ' The move vector will move the circle 2 units
  ' along the x axis.
  Dim point1(0 To 2) As Double
  Dim point2(0 To 2) As Double
  point1(0) = 0: point1(1) = 0: point1(2) = 0
  point2(0) = 2: point2(1) = 0: point2(2) = 0

  ' Move the circle
  circleObj.Move point1, point2
  circleObj.Update
End Sub
