vb.net查询cad cad如何调用vb程序

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 。
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 。
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
