　　一个三维模型中可能包含对应多张二维图纸列表，如果在在上传转换时设置导出二维图纸，则转换完成后三维模型自动关联所有的二维图纸。

　　在BIM查看器的左上角【视图】->【目录树】下拉选项中选择“图纸”选项，如果三维模型包含二维图纸，则在上传转换时设置导出二维图纸，则此处就会列出所有的图纸。双击一个图纸，右上侧显示该图纸。当双击三维模型的构件时，如果包含对应的二维图纸，则自动定位到二维图纸上；双击二维图纸上的图元时，自动定位到三维模型的构件。

本篇主要介绍如何获取模型文件对应的图纸列表。

请求地址：GET https://api.bimface.com/data/v2/files/{fileId}/drawingsheets

说明：获取单个模型文件对应的图纸列表。如果请求参数elementId为null，返回所有图纸，否则返回包含该构件的所有图纸。

参数：

请求 path(示例)：https://api.bimface.com/data/v2/files/1211223382064960/drawingsheets

请求 header(示例)："Authorization: Bearer dc671840-bacc-4dc5-a134-97c1918d664b"

HTTP响应示例(200)：

返回结果的结构比较复杂。封装成对应的 C# 类，SingleModelDrawingSheets

/// <summary>
///  获取单个模型的图纸列表返回的结果类
/// </summary>
[Serializable]
public class SingleModelDrawingSheets : GeneralResponse<List<DrawingSheet>>
{

}

引用的 DrawingSheet 类

/// <summary>
///  图纸信息类
/// </summary>
[Serializable]
public class DrawingSheet
{
    /// <summary>
    ///  文件ID 
    /// </summary>
    [JsonProperty("fileId")]
    public long? FileId { get; set; }

    /// <summary>
    ///  样例 : [ 0.0 ]
    /// </summary>
    [JsonProperty("portsAndViews")]
    public PortAndView[] PortAndViews { get; set; }

    [JsonProperty("viewInfo")]
    public ViewInfo ViewInfo { get; set; }

    /// <summary>返回表示当前对象的字符串。</summary>
    /// <returns>表示当前对象的字符串。</returns>
    public override string ToString()
    {
        return String.Format("[fileId={0}, portAndViews={1}, viewInfo={2}]",
                             FileId, PortAndViews.ToStringLine(), ViewInfo);
    }
}

引用的 PortAndView 类

[Serializable]
public class PortAndView
{
    /// <summary>
    ///  样例 :  0.0 
    /// </summary>
    [JsonProperty("elevation")]
    public double? Elevation { get; set; }

    /// <summary>
    ///  样例 : [ 0.0 ]
    /// </summary>
    [JsonProperty("outline")]
    public double?[] Outline { get; set; }

    /// <summary>
    ///  样例 :  "6278f2c7786043d4a35ae4115571b7c8"
    /// </summary>
    [JsonProperty("viewId")]
    public string ViewId { get; set; }

    [JsonProperty("viewPoint")]
    public ViewPoint ViewPoint { get; set; }

    /// <summary>
    ///  样例 : "viewType"
    /// </summary>
    [JsonProperty("viewType")]
    public string ViewType { get; set; }

    /// <summary>
    ///  样例 : [ 0.0 ]
    /// </summary>
    [JsonProperty("viewport")]
    public double?[] Viewport { get; set; }

    /// <summary>返回表示当前对象的字符串。</summary>
    /// <returns>表示当前对象的字符串。</returns>
    public override string ToString()
    {
        return String.Format("[elevation={0}, outline={1}, viewId={2}, viewPoint={3}, viewType={4}, viewport={5}]",
                             Elevation, Outline.ToStringWith(","), ViewId, ViewPoint, ViewType, Viewport.ToStringWith(","));
    }
}

引用的 ViewPoint 类

[Serializable]
public class ViewPoint
{
    /// <summary>
    ///  样例 : [ 0.0 ]
    /// </summary>
    [JsonProperty("origin")]
    public double?[] Origin { get; set; }

    /// <summary>
    ///  样例 : [ 0.0 ]
    /// </summary>
    [JsonProperty("rightDirection")]
    public double?[] RightDirection { get; set; }

    /// <summary>
    ///  样例 : [ 0.0 ]
    /// </summary>
    [JsonProperty("scale")]
    public int? Scale { get; set; }

    /// <summary>
    ///  样例 : [ 0.0 ]
    /// </summary>
    [JsonProperty("upDirection")]
    public double?[] UpDirection { get; set; }

    /// <summary>
    ///  样例 : [ 0.0 ]
    /// </summary>
    [JsonProperty("viewDirection")]
    public double?[] ViewDirection { get; set; }

    /// <summary>返回表示当前对象的字符串。</summary>
    /// <returns>表示当前对象的字符串。</returns>
    public override string ToString()
    {
        return String.Format("[origin={0}, rightDirection={1}, scale={2}， upDirection={3}, ViewDirection={4}]",
                             Origin.ToStringWith(","), RightDirection.ToStringWith(","), Scale, UpDirection.ToStringWith(","),
                             ViewDirection.ToStringWith(","));
    }
}

C#实现方法：

12     string url = string.Format(BimfaceConstants.API_HOST + "/data/v2/files/{0}/drawingsheets", fileId);
13     if (!string.IsNullOrWhiteSpace(elementId))

26         HttpResult httpResult = httpManager.Get(url);
27         if (httpResult.Status == HttpResult.STATUS_SUCCESS)
28         {
29             response = httpResult.Text.DeserializeJsonToObject<SingleModelDrawingSheets>();
30         }
31         else

测试

在BIMFACE的控制台中可以看到我们上传的文件列表，模型状态均为转换成功。

使用“bimface_2018_mdv_room.rvt”为例测试上述方法。

完整的图纸列表信息为：

测试代码如下：

// 获取图纸列表
protected void btnGetSingleModelDrawingSheets_Click(object sender, EventArgs e)
{
    long fileId = txtFileID.Text.Trim().ToLong();
    string elementId = txtElementId.Text.Trim();
    FileConvertApi api = new FileConvertApi();
    SingleModelDrawingSheets response = api.GetSingleModelDrawingSheets(txtAccessToken.Text, fileId, elementId);

    txtResult.Text = response.Code.ToString2()
                   + Environment.NewLine
                   + response.Message.ToString2()
                   + Environment.NewLine
                   + response.Data.ToStringLine();
}
