源文件/模型转换完成之后，可以获取模型的具体数据。本篇介绍根据文件ID查询满足条件的构件ID列表。
请求地址：GET https://api.bimface.com/data/v2/files/{fileId}/elementIds
说明：根据六个维度（专业，系统类型，楼层，构件类型，族，族类型）获取对应的构件ID列表，任何维度都是可选的。
构件ID分页查询相关请参考这里
同时，也支持根据空间关系从房间计算出房间内的构件ID列表
构件与房间空间关系计算相关请参考这里
参数：
请求 path(示例)：https://api.bimface.com/data/v2/files/1211223382064960/elementIds
请求 header(示例)："Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"
HTTP响应示例(200)：
{ "code": "success", "message": null, "data": [ "1107237", "1109326", "1107234", "1109327", "1107235", "1107239", "1109329", "1107236", "1109325", "1107238", "1109328" ] }
C#实现方法：
1 /// <summary> 2 /// 查询满足条件的构件ID列表 3 /// </summary> 4 /// <param name="accessToken">令牌</param> 5 /// <param name="fileId">文件ID</param> 6 /// <param name="request">请求参数对象</param> 7 /// <returns></returns> 8 public virtual FileElementsGetResponse GetFileElements(string accessToken, string fileId, FileElementsGetRequest request = null) 9 { 10 // GET https://api.bimface.com/data/v2/files/{fileId}/elementIds 11 string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/elementIds", fileId); 12 13 BimFaceHttpHeaders headers = new BimFaceHttpHeaders(); 14 headers.AddOAuth2Header(accessToken); 15 16 string data = string.Empty; 17 if (request != null) 18 { 19 data = request.SerializeToJson(); 20 } 21 22 try 23 { 24 FileElementsGetResponse response; 25 26 HttpManager httpManager = new HttpManager(headers); 27 HttpResult httpResult = httpManager.Get(url, data); 28 if (httpResult.Status == HttpResult.STATUS_SUCCESS) 29 { 30 response = httpResult.Text.DeserializeJsonToObject<FileElementsGetResponse>(); 31 } 32 else 33 { 34 response = new FileElementsGetResponse 35 { 36 Message = httpResult.RefText 37 }; 38 } 39 40 return response; 41 } 42 catch (Exception ex) 43 { 44 throw new Exception("[查询满足条件的构件ID列表]发生异常！", ex); 45 } 46 }
其中调用到的 httpManager.Get() 方法，请参考《C# HTTP系列》

参数都是可选的，如果不设置，则默认不添加到请求中。
在BIMFACE的控制台中可以看到我们上传的文件列表，共计2个文件。模型状态均为转换成功。
以“01_BIMFACE示例文件-Revit模型.rvt”为例查询其构建ID列表
查看结果中返回了构建ID列表。
如果使用 .dwg 二维文件进行测试则返回一下信息：unsupported operation:[please upgrade this databag to support specialty tree]
查询满足条件的构件ID列表 ，只对三维模型适用。二维图纸没有目录树。
测试代码如下：
// 查询满足条件的构件ID列表 protected void btnGetFileElements_Click(object sender, EventArgs e) { FileConvertApi api = new FileConvertApi(); FileElementsGetResponse response = api.GetFileElements(txtAccessToken.Text, txtFileID.Text); txtResult.Text = response.Code.ToString2() + Environment.NewLine + response.Message.ToString2() + Environment.NewLine + response.Data.ToStringWith(","); }
查询构建ID列表返回类 FileElementsGetResponse
/// <summary> /// 查询满足条件的构件ID列表返回的结果类 /// </summary> public class FileElementsGetResponse : GeneralResponse<List<string>> { }
