cass获取界址线每条线段属性
代码如下，运行结果显示每段线的属性都为空值，但用cass导出属性，有属性数据，有起点号和终点号等属性，求高手解答！！！Sub test4()
On Error Resume Next
Dim obj As AcadEntity, pnt, oVers
Dim xt, xd
Dim i As Integer
Dim s As String, j As Integer
ThisDrawing.Utility.GetEntity obj, pnt, "请选择界址线所在的宗地："
oVers = GetVertexs(obj)
If oVers <> vbEmpty Then
For i = 0 To UBound(oVers)
s = ""
Call oVers(i).GetXData("", xt, xd)
Debug.Print UBound(xd)
For j = 0 To UBound(xd)
s = s & vbCrLf & xd(j)
Next j
If Err Then
Err.Clear
MsgBox "空值"
Else
MsgBox s
End If
Next i
Else
MsgBox "错误选择"
End If
End Sub
Function GetVertexs(Ent As AcadEntity) As Variant
Dim n As Integer
Dim oVertexs() As AcadObject
Dim sName As String
sName = UCase(Ent.ObjectName)
Dim lst
Dim i As Integer
Debug.Print sName & "aaa" & UBound(Ent.Coordinates)
If sName = "ACDB2DPOLYLINE" Or sName = "ACDB3DPOLYLINE" Then
n = (UBound(Ent.Coordinates) + 1) / 3
End If
Debug.Print n
If n = 0 Then Exit Function
ReDim oVertexs(n - 1)
Dim oVlax As New VLAX
lst = oVlax.GetLispList("(GetVers """ & Ent.Handle & """)")
Debug.Print Ent.Handle
For i = 1 To n
Set oVertexs(i - 1) = ThisDrawing.HandleToObject(lst(n - i))
Debug.Print oVertexs(i - 1).Handle
Next i
GetVertexs = oVertexs
End Function
