  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"
    ]
}

11     string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/elementIds", fileId);

13     BimFaceHttpHeaders headers = new BimFaceHttpHeaders();
14     headers.AddOAuth2Header(accessToken);

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》

测试

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>>
{
}
