vb.netcadgetpoint如何只能选切点

利用CAD对象捕捉功能。通过查询netcadgetpoint官网得知，vbnetcadgetpoint可以利用CAD对象捕捉功能才能选切点，vbnetcadgetpoint在新基建工程对话框当选择工程部类为Visual Basic工程。

Q1: vb.net如何在编程中获取CAD对象的DXF组码

感觉 vb.net对象中根本不存在组码这个东西，一切皆对象。直接遍历访问，要对应组码有何用？如果你想获取组码一句简单lsp语句就行了。

Q2: VB.Net读取AutoCAD图纸

如果可以vb.net查询cad的话请把分给vb.net查询cad我

以下是cad2007版的，引用autocad 2007 type library 和autocad/objectdbx common 17如果是04或者版本更低的只要引用autocad 2007 type library，代码的话大同小异，思路是一样的

 

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        On Error Resume Next

        Dim acadapp As Autodesk.AutoCAD.Interop.AcadApplication

acadapp = GetObject(vbNullString, "autoCAD.application")

        Dim acaddoc As Autodesk.AutoCAD.Interop.AcadDocument

        acaddoc = acadapp.ActiveDocument

        Dim Ms As Autodesk.AutoCAD.Interop.Common.AcadModelSpace

        Ms = acaddoc.ModelSpace

        Dim acadObjectI As Autodesk.AutoCAD.Interop.Common.AcadObject

        Dim Linei As Autodesk.AutoCAD.Interop.Common.AcadLine

        Dim Circlei As Autodesk.AutoCAD.Interop.Common.AcadCircle

        Dim Polylinei As Autodesk.AutoCAD.Interop.Common.AcadPolyline

        Dim pt As Autodesk.AutoCAD.Interop.Common.AcadPoint

For Each acadObjectI In Ms

            Debug.Print(acadObjectI.ObjectName)

            Select Case acadObjectI.ObjectName

                Case "AcDbLine"

                    Linei = acadObjectI

                    Debug.Print("X =" Linei.StartPoint(0).ToString)

                    Debug.Print("Y =" Linei.StartPoint(1).ToString)

                Case ""

                Case ""

End Select

Next

    End Sub
