[VBA]如何得到当前文档的当前无名ucs的转换矩阵？
rt autodesk的代码如下，按照原理应该可行，可惜坐标转换之后保存的OriginalUCS有错误。郁闷啊。Sub Example_ActiveUCS1()
' This example returns the current saved UCS (or saves a new one dynamically)
' and then sets a new UCS.
' Finally, it returns the UCS to the previous setting.
Dim newUCS As AcadUCS
Dim currUCS As AcadUCS
Dim origin(0 To 2) As Double
Dim xAxis(0 To 2) As Double
Dim yAxis(0 To 2) As Double
Dim pnt As Variant
' Get the current saved UCS of the active document. If the current UCS is
' not saved, then add a new UCS to the UserCoordinateSystems collection
If ThisDrawing.GetVariable("UCSNAME") = "" Then
' Current UCS is not saved so get the data and save it
With ThisDrawing
Set currUCS = .UserCoordinateSystems.Add( _
.GetVariable("UCSORG"), _
.Utility.TranslateCoordinates(.GetVariable("UCSXDIR"), acUCS, acWorld, 0), _
.Utility.TranslateCoordinates(.GetVariable("UCSYDIR"), acUCS, acWorld, 0), _
"OriginalUCS")
End With
Else
Set currUCS = ThisDrawing.ActiveUCS'current UCS is saved
End If
' .Utility.TranslateCoordinates(.GetVariable("UCSXDIR"), acUCS, acWorld, 0), _
' .Utility.TranslateCoordinates(.GetVariable("UCSYDIR"), acUCS, acWorld, 0), _
'
pnt = ThisDrawing.GetVariable("UCSORG")
Debug.Print pnt(0); pnt(1); pnt(2)
pnt = ThisDrawing.GetVariable("UCSXDIR")
Debug.Print pnt(0); pnt(1); pnt(2)
pnt = ThisDrawing.GetVariable("UCSYDIR")
Debug.Print pnt(0); pnt(1); pnt(2)
pnt = ThisDrawing.Utility.TranslateCoordinates(ThisDrawing.GetVariable("UCSXDIR"), acUCS, acWorld, 0)
Debug.Print pnt(0); pnt(1); pnt(2)
pnt = ThisDrawing.Utility.TranslateCoordinates(ThisDrawing.GetVariable("UCSYDIR"), acUCS, acWorld, 0)
Debug.Print pnt(0); pnt(1); pnt(2)
MsgBox "The current UCS is " & currUCS.Name, vbInformation, "ActiveUCS Example"
' Create a UCS and make it current
origin(0) = 0: origin(1) = 0: origin(2) = 0
xAxis(0) = 1: xAxis(1) = 1: xAxis(2) = 0
yAxis(0) = -1: yAxis(1) = 1: yAxis(2) = 0
Set newUCS = ThisDrawing.UserCoordinateSystems.Add(origin, xAxis, yAxis, "TestUCS")
ThisDrawing.ActiveUCS = newUCS
MsgBox "The new UCS is " & newUCS.Name, vbInformation, "ActiveUCS Example"
' Reset the UCS to its previous setting
ThisDrawing.ActiveUCS = currUCS
MsgBox "The UCS is reset to " & currUCS.Name, vbInformation, "ActiveUCS Example"
End Sub
这样就好了。呵呵。小心autodesk蒙人。
If ThisDrawing.GetVariable("UCSNAME") = "" Then
' Current UCS is not saved so get the data and save it '.GetVariable("UCSORG"),
With ThisDrawing
Set currUCS = .UserCoordinateSystems.Add( _
pnt1, _
.GetVariable("UCSXDIR"), _
.GetVariable("UCSYDIR"), _
"OriginalUCS")
currUCS.origin = .GetVariable("UCSORG")
End With
Else
Set currUCS = ThisDrawing.ActiveUCS'current UCS is saved
End If
