使用最新的 BIMServer 1.4.0 我无法加载我的模型。返回模型，但它不包含任何类。ifc的生命周期：

我这样初始化

        PluginManager pluginManager = LocalDevPluginLoader.createPluginManager(Paths.get("home"));
        pluginManager.loadPluginsFromCurrentClassloader();
        // Create a MetaDataManager, and initialize it, this code will be simplified/hidden in the future
        MetaDataManager metaDataManager = new MetaDataManager(pluginManager);
        pluginManager.setMetaDataManager(metaDataManager);
        metaDataManager.init();

        // Initialize all loaded plugins
        pluginManager.initAllLoadedPlugins();

        // Create a factory for BimServerClients, connnect via JSON in this case
        BimServerClientFactory factory = new JsonBimServerClientFactory(metaDataManager, "http://localhost:8082");

        // Create a new client, with given authorization, replace this with your credentials
        BimServerClientInterface client = factory.create(new UsernamePasswordAuthenticationInfo("admin@bimserver.org", "none"));
        setup(client);

使用此代码通过 bimviews gui（IFC2x3 Step deserializer）签入我尝试获取模型

  List<SProject> project = client.getBimsie1ServiceInterface().getProjectsByName("BIM");
        SProject newProject = client.getBimsie1ServiceInterface().getProjectByPoid(project.get(0).getOid());

        return client.getModel(newProject, newProject.getLastRevisionId(), true, false, true);

获得任何课程（例如 IFCSlab 等）都被证明是不成功的，因为它里面没有任何东西我尝试在 bimviews 中将其可视化并且它在那里工作。

IFC 示例： http ://www.mediafire.com/file/8i8v7kfcou3ok2c/IFC_%25C3%2596ffnungen.ifc/file

这个过程有什么问题吗？

你可以试试上面的代码吗？

            }

    }
    return detectorNames;
}
}

我特意给出了导入语句，因为您需要特定于您要检查的 ifc 格式类型，即 ifc2x3 或 ifc4。这是我使用的代码，它对我来说很好，只需使用其余端点。 只需替换项目的名称。请让我知道输出。您可以根据需要提取信息。

注意： 此代码针对 BimServer 1.5.111 和 ifc2x3 进行了测试

此外，IfcBuildingStorey 是楼层或级别，IfcRelContainedInSpatialStructure 就像一些探测器，因此您可以根据需要进行修改。
