/// 2.在不打开Revit的情况下读取rvt文件数据
在Revit插件中可以在后台打开rvt文件，并且访问他的数据，但是这个数据读取时依赖于Revit软件的。
就是说必须要在Revit打开的情况下，运行一个插件，在插件代码里读取rvt 的信息
我准备了一个机电测试文件，这个项目文件里面一共画了三个构建：一个长度为8800mm的风管，一个长度为6600mm的水管和一个桥架
下面的例子实现了打开一个rvt文件，并且过滤其中的风管类型的构建，并且获取风管实例的长度，结果确实是8800mm

foreach(CompoundStructureLayer item in compoundStructure.GetLayers())
{
if (item.MaterialId == ElementId.InvalidElementId) continue;
Material m = doc.GetElement(item.MaterialId) as Material;
if (m == null) continue;
info += m.Name + "\n";
}
TaskDialog.Show("墙体结构材质",info);
return Result.Succeeded;
}
}
}
7.取消选中元素

{
UIDocument uidoc = commandData.Application.ActiveUIDocument;
Document doc = uidoc.Document;
Selection selection = uidoc.Selection;
IList<Reference> reffs = selection.PickObjects(ObjectType.Element);
string info = string.Empty;
foreach(var item in reffs)
{
info += doc.GetElement(item).Name + "\n";
}
info += "点击确认三秒钟以后会自动取消选中地元素";
TaskDialog.Show("Title", info);
Thread.Sleep(3 * 1000);
// 方法1
elementSet.Clear();
// 方法2
selection.SetElementIds(new List<ElementId>());
return Result.Succeeded;
}
}
}
8.选中元素
2015以后的版本都用selection.SetElementIds(List ids)这个方法来设置元素选中。
using System;
using System.Collections.Generic;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.DB.Mechanical;
using Autodesk.Revit.DB.Plumbing;
using Autodesk.Revit.DB.Electrical;
using System.Threading;
namespace 插件
{
[Autodesk.Revit.Attributes.Transaction(TransactionMode.Manual)]
[Autodesk.Revit.Attributes.Regeneration(RegenerationOption.Manual)]
[Autodesk.Revit.Attributes.Journaling(JournalingMode.UsingCommandData)]
public class Command : IExternalCommand
{
public readonly double unit = 304.8;
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet)
{
UIDocument uidoc = commandData.Application.ActiveUIDocument;
Document doc = uidoc.Document;
Selection selection = uidoc.Selection;
Reference reff = selection.PickObject(ObjectType.Element);
Element elem = doc.GetElement(reff);
selection.SetElementIds(new List<ElementId>() { elem.Id});
TaskDialog.Show("选择", "已经选中");
Thread.Sleep(2*1000);
// 传入一个空的列表，即取消选中
selection.SetElementIds(new List<ElementId>());
return Result.Succeeded;
}
}
}
9获取元素的几何信息
Revit中元素的几何信息可以通过get_Geometry(Options)方法获取，这个方法返回一个GeometryElement类型的值，GeometryElement里面包含了这个元素所有的GeometryObject
这个函数需要传入一个Options的参数，Options有一个默认无参数的构造器，Options类有下面几个属性可以设置：
| 属性 | 说明 |
|---|---|
| ComputeReferences | 这是一个布尔值，如果是true,那么返回的Reference不为空，默认为false |
| IncludeNonVisibleObjects | 设置是否包含不可见的几何 |
| DetailLevel | 对应视图的详细程度 |
| IsReadOnly | 是否只读 |
| View | 返回这个视图中可见的几何 |
- 如果族是载入族，要看是否是剪切过的族，如果是剪切过的族，那么方法与系统族类似
- 如果不是剪切过的族，那么
- 通过XX.get_Geometry(opt)获取到GeometryElement
- 再从GeometryElement获取到GeometryInstance,再从GeometryInstance.GetInstanceGeometr()或者GeometryInstance.GetSymbolGeometry()获取Solid进行操作
GeometryObject有下面的几个子类:
- Autodesk.Revit.DB.XX.Curve
- Autodesk.Revit.DB.XX.Face
- Autodesk.Revit.Db.XX.Edge
- Autodesk.Revit.DB.XX.GeometryElement
- Autodek.Revit.DB.XX.GeometryInstance
- Autodesk.Revit.DB.XX.Mesh
- Autodesk.Revit.DB.XX.Point
- Autodesk.Revit.DB.XX.PolyLine
- Autodesk.Revit.DB.XX.Profile
- Autodesk.Revit.DB.XX.Solid
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet)
{
UIDocument uidoc = commandData.Application.ActiveUIDocument;
Document doc = uidoc.Document;
Selection selection = uidoc.Selection;
Options opt = new Options
{
ComputeReferences = true,
DetailLevel = ViewDetailLevel.Fine,
IncludeNonVisibleObjects = false
};
// wall
Reference reff = selection.PickObject(ObjectType.Element, "选择一堵墙");
Wall wall = doc.GetElement(reff) as Wall;
GetWallBottomFaceAndComputeArea(wall, opt);
// column
Reference refColumn = selection.PickObject(ObjectType.Element, "请选择一个柱子");
FamilyInstance instance = doc.GetElement(refColumn) as FamilyInstance;
GetColumnBottomFaceAndComputeArea(instance, opt);
return Result.Succeeded;
}
///
/// 获取一个没有剪切的柱子实体最下面的面，并且输出面积
///
///
///
public void GetColumnBottomFaceAndComputeArea(FamilyInstance fmInstance,Options opt)
{
GeometryElement geoElem = fmInstance.get_Geometry(opt);
Face face = null;
foreach(GeometryObject obj in geoElem)
{
if(obj is Solid)
{
Solid solid = obj as Solid;
if(solid.Faces.Size>0)
{
face = FindBottomFace(solid);
}
}
else if(obj is GeometryInstance)
{
GeometryInstance gmInstance = obj as GeometryInstance;
// 获取实例的solid
GeometryElement geoElem1 = gmInstance.GetInstanceGeometry();
// 获取族类型的solid
//GeometryElement geoElem1 = gmInstance.GetSymbolGeometry();
foreach(GeometryObject obj2 in geoElem1)
{
if(obj2 is Solid)
{
Solid solid = obj2 as Solid;
if(solid.Faces.Size>0)
{
face = FindBottomFace(solid);
}
}
}
}
}
TaskDialog.Show("柱子的底面积", face.Area.ToString());
}
///
/// 获取墙体实体最下面的面，并且输出面积
///
///
///
public void GetWallBottomFaceAndComputeArea(Wall wall,Options opt)
{
GeometryElement geoElem = wall.get_Geometry(opt);
foreach(GeometryObject obj in geoElem)
{
Solid solid = obj as Solid;
// 排除获取到的不是实体和获取到的无效实体
if(solid!=null && solid.Faces.Size>0)
{
Face face = FindBottomFace(solid);
TaskDialog.Show("面积", face.Area.ToString());
}
