Question

我试图从.NET调用内置的AutoCad Electrical LISP命令(c:wd_insym2 "HPB11.dwg" (list 0 0) 1.0 nil)。我最近安装了AutoCad 2016，它现在有Editor.Command和Editor.CommandAsync功能，但是我能找到的所有帮助/论坛帖子都是用它来调用AutoCad命令，如LINE，CIRCLE等。我想调用lisp命令，例如：

0, 0

在<CommandMethod("SendCmdAsync", CommandFlags.Modal)> Async Sub SendCmdAsync() Dim doc As Document = DocumentManager.MdiActiveDocument Dim ed As Editor = doc.Editor Dim cmd As String = "(c:wd_insym2 " & ControlChars.Quote & "HPB11.dwg" & ControlChars.Quote & " (list 0 0) nil nil)" ed.WriteMessage(vbNewLine & "Trying to execute: <" & cmd & ">" & vbNewLine) Await ed.CommandAsync(cmd) ed.WriteMessage(vbNewLine & "Done.") End Sub处插入按钮符号。

这是我所拥有的（我一直在使用CommandAsync，因为我在使用Application.Invoke同步发送该命令时遇到了麻烦：AutoCad Command Rejected "Undo" when using Application.Invoke()

        return drive_service

    def push_file(self, file_src, title, description=''):
        media_body = googleapiclient.http.MediaFileUpload(
                file_src, mimetype=self.mimetype, resumable=True)
        body = {
            'title': title,
            'description': description
        }
        try:
            new_file = self.drive_service.files().insert(body=body,
                                                     media_body=media_body
                                                     ).execute()
            pprint.pprint(new_file)
        except googleapiclient.errors.HttpError as error:
            print('An error occured: %s' % error)


if __name__ == '__main__':
    d = DriveClient()
    d.push_file('document.txt', 'mTitle', 'mDescription')

当我运行它时，它说＆＃39; LISP命令不可用＆＃39;。

我做的是什么，如果是的话，我做错了什么？

我解决了这个问题 - 显然你不能使用Command和CommandAsync来运行Lisp命令 - 它们只适用于AutoCAD命令。

执行此操作的最佳方法是Application.Invoke：https://forums.autodesk.com/t5/net/unable-to-find-an-entry-point-in-dll-acad-exe/m-p/5522036/highlight/true#M43404

虽然，通过我的特定电气命令（c：wd_insym2），当我在AutoCAD 2014中尝试这种技术时，它会给我一个错误'AutoCAD命令拒绝UNDO'。但是，我刚刚注意到在AutoCAD 2016中它工作正常 - 我猜他们已经在某处改变了API。

从AutoCAD .NET Editor.CommandAsync调用LISP命令
