c#.net + AutoCAD2006,请问如何得到直线、和多义线的端点坐标呢？迫切想知道，谢谢各位！[br]c#.net + AutoCAD2006,请问如何得到直线端点坐标和多义线的各个顶点坐标？我需要得到这些点的坐标，然后由这些坐标绘出新的直线。望各位大侠指教！

顶起来 有知道的吗

到对象浏览器里看看Line,PolyLine类

我告你，用com写的，

  If ent.objectname.Equals("AcDbPolyline") Then
                    Dim objpl As IAcadLWPolyline = CType(ent, IAcadLWPolyline)
                    Dim pt12(0 To 2) As Double : Dim pt23(0 To 2) As Double
                    Dim obj1 As Object : Dim obj2 As Object : Dim obj3 As Object : Dim obj4 As Object
                    Dim pt1(0 To 2) As Double : Dim pt2(0 To 2) As Double : Dim pt3(0 To 2) As Double : Dim pt4(0 To 2) As Double
                    obj1 = objpl.Coordinate(0)
                    obj2 = objpl.Coordinate(1)
                    obj3 = objpl.Coordinate(2)
                    obj4 = objpl.Coordinate(3)
                    pt1(0) = obj1(0) : pt1(1) = obj1(1) : pt1(2) = 0
                    pt2(0) = obj2(0) : pt2(1) = obj2(1) : pt2(2) = 0
                    pt3(0) = obj3(0) : pt3(1) = obj3(1) : pt3(2) = 0
                    pt4(0) = obj4(0) : pt4(1) = obj4(1) : pt4(2) = 0
                    pt12(0) = pt(0) : pt12(1) = pt2(1) : pt12(2) = 0
                    pt23(0) = pt3(0) : pt23(1) = pt(1) : pt23(2) = 0
                                   End If

刚才是多义线，直线的两个端点对应于属性 startPoint  和  endPoint

一看lz，应该是个初学者，这个问题简单，就不用我来说了
