hi, i know there are a lot of posted messages already on this, but i still haven't found a solution for my problem. For Each dimST In ThisDrawing.DimStyles If dimST.Name = "BBS_LABELS" Then ThisDrawing.ActiveDimStyle = dimST Next ThisDrawing.SetVariable "DIMSCALE", sc when i do this, it creates an override with the new sc factor ,but the original stays the same. I want the original to change with the sc factor. How do i do that? thanks in advance, Emmanuel ' draw temporary dimline On Error GoTo ErrorHandler p1 = ThisDrawing.Utility.GetPoint(, vbCr & "Specify first extension line origin: ") p2 = ThisDrawing.Utility.GetPoint(p1, vbCr & "Specify second extension line origin: ") Data(3) = p1 On Error Resume Next Set dimobj = ThisDrawing.ModelSpace.AddDimAligned(p1, p2, p2)
