revit二次开发API示例 SpatialFieldGradient在Revit 模型中显示分析结果

应用程序名称: SpatialFieldGradient

Revit 平台: 所有

Revit 版本: 2011.0

首次发布版本: 2011.0

编程语言: C#

技能级别: 高级

类别: 几何

Autodesk.Revit.DB.Analysis.AnalysisDisplayLegendSettings

Autodesk.Revit.DB.Analysis.AnalysisDisplayStyle

Autodesk.Revit.DB.Analysis.FieldDomainPointsByUV

Autodesk.Revit.DB.Analysis.FieldValues

项目文件：

Command.cs

描述：

1. 创建一个 AnalysisDisplayColoredSurfaceSettings 对象，并设置其在表面上显示网格线。

2. 创建一个 AnalysisDisplayColorSettings 对象，并设置最小和最大颜色。

3. 创建一个 AnalysisDisplayLegendSettings 对象，并指定各种图例设置。

4. 使用前面创建的设置创建一个 Analysis Display 样式。

5. 将活动视图设置为使用此 Analysis Display 样式。

6. 创建一个列表（measureNames），以便每个数据点可以存储多个值。

7. 创建列表（unitNames 和 multipliers），以便数据可以以英尺和英寸的形式显示。

8. 当选择一个面时

a. 将面的 U 和 V 参数化划分为每个方向 10 个线段。

b. 基于每个点的面的 U 值创建三个值（U、U +1、U * 10）。

9. 更新空间场原语以在面上显示此数据。

说明：

1. 运行外部命令。

2. 选择一个面。
