应用程序启动了没
dim acadApp As AcadApplication

你去查查书吧，书上挺详细的，在这说不好说，你先在项目里引用。然后 Dim acadapp As AcadApplication Dim acaddoc As AcadDocument On Error Resume Next AcadApp = GetObject(, "AutoCAD.Application") If Err.Number Then Err.Clear() AcadApp = CreateObject("AutoCAD.Application") If Err.Number Then MsgBox("不能运行AutoCAD,请检查是否安装了AutoCAD") Exit Sub End If End If AcadApp.Visible = True '界面可视
