AutoCAD /地圖3D將當前測量值放入文本覆蓋

Question

我正在使用Map 3D繪製不精確的地圖。我有尺寸我可以與繪圖重疊的DWG。我需要對齊這些維度，但我不想在每次拉伸它後輸入值。有沒有辦法將測量結果修改爲不改變？

Answer 1

我不相信這是有關編程，但可以override dimension values AutoCAD平臺。

您可以嘗試in VB

Sub OverrideDimensionText() 
Dim dimObj As AcadDimAligned 
Dim point1(0 To 2) As Double 
Dim point2(0 To 2) As Double 
Dim location(0 To 2) As Double 

' Define the dimension 
point1(0) = 5#: point1(1) = 3#: point1(2) = 0# 
point2(0) = 10#: point2(1) = 3#: point2(2) = 0# 
location(0) = 7.5: location(1) = 5#: location(2) = 0# 

' Create an aligned dimension object in model space 
Set dimObj = ThisDrawing.ModelSpace. _ 
       AddDimAligned(point1, point2, location) 

' Change the text string for the dimension 
dimObj.TextOverride = "The value is <>" 
dimObj.Update 
End Sub 

Answer 2

更新： 我是錯的最後一條語句，但在這裏是解決方案： http://www.cadtutor.net/forum/archive/index.php/t-31690.html VVA得到最終的Lisp代碼。用命令DIMO它會覆蓋文本。
