我遇到了一个问题，我需要用指定的模板文件打开一个新的绘图文件，如下所示。
objInventorServer.Documents.Add(Inventor.DocumentTypeEnum.kDrawingDocumentObject, templatePath)
但是这一行在工作项日志中给出了一个未指定的错误。我猜 InventorServer 对象正在发生问题。 因为在具有普通 Inventor.Application 对象的本地计算机中使用同一行时，它工作正常。请帮我解决问题。

如果绘图文件来自比我正在运行的 Inventor 服务器更新的版本，我只会遇到问题，但随后我收到了更多消息：

但在这种情况下，Open 也会失败 ?
如果我对文件和 Inventor Server 使用相同的版本，则此代码成功：
public void RunWithArguments(Document doc, NameValueMap map)
{
LogTrace("RunWithArguments called");
string idwPath = map.Item["_1"];
LogTrace("Creating drawing based on template " + idwPath);
LogTrace("FileExists = " + System.IO.File.Exists(idwPath).ToString());
Document idwDoc = inventorApplication.Documents.Add(Inventor.DocumentTypeEnum.kDrawingDocumentObject, idwPath);
LogTrace("Created drawing based on template " + idwPath);
}
这是报告：

您的所有 Inventor 工程图模板是否都遇到过这个问题？
【讨论】：
您需要正确指定templatePath。这必须是本地完整文件名。无法打开此文件。模板必须是您的输入数据或应用程序包的一部分。路径如下所示：T:\Aces\Jobs\9b8d2f73366f47a0a0b90b8c522bd52b\CadData\Templates\Norma.idw
