Revit二次开发API示例 FoundationSlab地基基础板
648
2024/09/29
应用程序: FoundationSlab
Revit平台: 所有
Revit版本: 2011.0
首次发布: 9.1
编程语言: C#
技能水平: 中级
类别: 元素
类型: 外部命令
主题: 创建基础板。
摘要：
本示例演示如何创建基础板。
相关类：
Autodesk.Revit.UI.IExternalCommand
Autodesk.Revit.DB.Floor
Autodesk.Revit.DB.FloorType
Autodesk.Revit.DB.Document
项目文件：
Command.cs
该文件包含实现接口IExternalCommand的Command类。它创建了一个基础板表单的SlabData实例并显示该表单。
RegularSlab.cs
该文件包含一个常规板的类。按照其边界框创建一个八边形剖面。
FoundationSlabForm.cs
该文件包含一个显示基础板属性和剖面的类。
SlabData.cs
该文件包含一个SlabData类，它是RevitAPI和FoundationSlabForm之间的中介者。它具有一组函数来创建基础板，查找所有常规水平板，获取板的剖面，验证板是否平面等。
Sketch.cs
该文件包含一个用于绘制板的剖面的内部类。
描述：
- 要获取板，需要通过文档迭代来查找'Floor'对象。
- 在floor参数中可以找到Mark属性：BuiltInParameter.ALL_MODEL_MARK。
- 可以通过迭代文档来查找类别为“结构基础”的“FloorType”对象来找到基础板类型。
- 可以通过使用给定的水平剖面和指定的基础板样式的'NewFloor'方法创建基础板。
- 结构板的剖面可以在其AnalyticalModel属性中找到。非结构地面的剖面可以通过其Geometry属性形成。
- 八边形剖面是一个由平面线组成的数组，表示八边形基础板的水平剖面。
- 确保板的剖面是一个封闭的轮廓线，否则它不能被Revit创建。
说明：
1. 准备Revit项目。
打开或新建Revit项目，确保文档中有一些地板。示例项目文件FoundationSlab.rvt可在示例文件夹中找到。
2. 运行命令。
3. 在常规板组中，选择要进行更改的地板。
4. 在对话框底部，选择要应用的基础板类型。
5. 您可以在Picture Box中看到转换结果的预览。单击OK按钮以为选定的地板创建八边形板。
