请给个Vla－setxdata 赋值的例子。
谢谢。在这里
Sub Example_SetXdata()' This example creates a line and attaches extended data to that line.
' Create the line
Dim lineObj As AcadLine
Dim startPt(0 To 2) As Double, endPt(0 To 2) As Double
startPt(0) = 1#: startPt(1) = 1#: startPt(2) = 0#
endPt(0) = 5#: endPt(1) = 5#: endPt(2) = 0#
Set lineObj = ThisDrawing.ModelSpace.AddLine(startPt, endPt)
ZoomAll
' Initialize all the xdata values. Note that first data in the list should be
' application name and first datatype code should be 1001
Dim DataType(0 To 9) As Integer
Dim Data(0 To 9) As Variant
Dim reals3(0 To 2) As Double
Dim worldPos(0 To 2) As Double
DataType(0) = 1001: Data(0) = "Test_Application"
DataType(1) = 1000: Data(1) = "This is a test for xdata"
DataType(2) = 1003: Data(2) = "0" ' layer
DataType(3) = 1040: Data(3) = 1.23479137438413E+40' real
DataType(4) = 1041: Data(4) = 1237324938 ' distance
DataType(5) = 1070: Data(5) = 32767 ' 16 bit Integer
DataType(6) = 1071: Data(6) = 32767 ' 32 bit Integer
DataType(7) = 1042: Data(7) = 10 ' scaleFactor
reals3(0) = -2.95: reals3(1) = 100: reals3(2) = -20
DataType(8) = 1010: Data(8) = reals3 ' real
worldPos(0) = 4: worldPos(1) = 400.99999999: worldPos(2) = 2.798989
DataType(9) = 1011: Data(9) = worldPos ' world space position
' Attach the xdata to the line
lineObj.SetXData DataType, Data
' Return the xdata for the line
Dim xdataOut As Variant
Dim xtypeOut As Variant
lineObj.GetXData "", xtypeOut, xdataOut
End Sub
我的意思不是用VBA，是在Lisp中应用。
我对VBA不熟悉，只会一点lisp。实用函数栏目有两个函数可用
ax:GetXData 获取附着在AutoCAD对象上的扩展图元数据http://www.mjtd.com/function/vlisp/038.htm
ax:PutXData 附着扩展图元数据到AutoCAD对象上
http://www.mjtd.com/function/vlisp/039.htm
收下了，谢谢。
