AcadDimRotated的起点和终点

如何获取a的起点和终点；AcadDimRotated以及如何分解AcadDimension

基本上，通过使用lisp dxf代码13,14，将其放入sub中&nbsp&nbsp&nbsp；varTest=vbAssoc（objDim，13）&nbsp&nbsp&nbsp；StartPt=ParseDxfPoint（varTest）&nbsp
&nbsp&nbsp&nbsp；varTest=vbAssoc（objDim，14）&nbsp&nbsp&nbsp；EndPt=ParseDxfPoint（varTest）
Function ParseDxfPoint(DxfPoint)
    Dim Pt(2) As Double
    Dim Gap1, Gap2
    Gap1 = InStr(2, DxfPoint, " ", vbTextCompare)
    Pt(0) = Mid(DxfPoint, 2, Gap1 - 1)
    Gap2 = InStr(Gap1 + 1, DxfPoint, " ", vbTextCompare)
    Pt(1) = Mid(DxfPoint, Gap1 + 1, Gap2 - (Gap1 + 1))
    Pt(2) = Mid(DxfPoint, Gap2 + 1, Len(DxfPoint) - (Gap2 + 1))
    ParseDxfPoint = Pt
   
End Function
