AutoCAD / Map 3D将当前测量值放入文本覆盖中

Question

我正在使用不精确的绘图在地图3d中工作。我有dwg尺寸我可以与图纸重叠。我需要对齐这些维度，但我不想在拉伸它之后每次输入值。有没有办法确定测量值不改变？

Answer 1

我不相信这与编程有关，但你可以在AutoCAD上override dimension values。

您可以尝试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

更新： 我最后一句话错了，但这是解决方案： http://www.cadtutor.net/forum/archive/index.php/t-31690.html VVA最终获得了lisp代码。使用命令DIMO，它将覆盖文本。
