RevitAPI(五) 建筑建模

一  标高和轴网

        

轴网 Grid

创建轴网
曲线：Grid Create(Document,Arc);
直线：Grid Create(Document,Line);
常用属性：
Curve:拿到轴网的线
IsCurved:true说明是Arc对象，否则是Line对象
Name:改轴网的名

注意：
1.轴网创建后名字会按照上一次的规则递增命名
2.传入的直线或弧线的平面必须是一个水平的

            //用与存储Revit的元素、管理视图和数据
            Document doc = uIDocument.Document;

            //删除
            Transaction transaction = new Transaction(doc, "轴网");

            XYZ start=uIDocument.Selection.PickPoint();
            XYZ end=uIDocument.Selection.PickPoint();

            Line line = Line.CreateBound(start,end);

    }
}

 标高Level

using Autodesk.Revit.ApplicationServices;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;

namespace Selection
{
    [Transaction(TransactionMode.Manual)]
    public class LevelTest : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            //UIApplication表示一个活动的Revit@会话，提供了对UI定制、事件以及活动文档的访问。

            var a=(doc.GetElement(new ElementId(53969))) as ViewFamilyType;
            ViewPlan.Create(doc,a.Id,level.Id);
            transaction.Commit();

            //

            return Result.Succeeded;
        }
    }
}

 二 宿主元素HostObject

  宿主元素(HostObject)子类有Wall、Floor、Ceiling、Roof      

        

1.获取复合结构通过宿主元素的类型如WalIType、FloorType得到如WallType.GetCompoundStructure()

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Autodesk.Revit.ApplicationServices;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.DB.Architecture;
using Autodesk.Revit.UI;
using Autodesk.Revit.UI.Events;
using Autodesk.Revit.UI.Selection;

namespace Selection
{
    [Transaction(TransactionMode.Manual)]
    public class CompoundStructureTest : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            //UIApplication表示一个活动的Revit@会话，提供了对UI定制、事件以及活动文档的访问。
            UIApplication uIApplication = commandData.Application;
            //Application类表示一个Revit应用，提供对文档、选项以及其他应用范围的数据的访问和设置。
            Application app = uIApplication.Application;
            //主要包含了跟UI相关的文档信息和操作,比如Active View和ShowElement
            UIDocument uIDocument = uIApplication.ActiveUIDocument;
            //用与存储Revit的元素、管理视图和数据
            Document doc = uIDocument.Document;

            //删除
            Transaction transaction = new Transaction(doc, "获取复合结构");
            transaction.Start();

            Reference reference= uIDocument.Selection.PickObject(ObjectType.Element);
            Wall wall=doc.GetElement(reference) as Wall;
            WallType wallType = wall.WallType;

            CompoundStructure compoundStructure = wallType.GetCompoundStructure();

            IList<CompoundStructureLayer> compoundStructures = compoundStructure.GetLayers();
            StringBuilder stringBuilder = new StringBuilder();
            foreach(var compoundStructureLayer in compoundStructures)
            {
                ElementId a =compoundStructureLayer.MaterialId;
                stringBuilder.AppendLine("序号:\t\t"+ compoundStructureLayer.LayerId.ToString());
                stringBuilder.AppendLine("材质:\t\t" + doc.GetElement(a).Name.ToString());
                stringBuilder.AppendLine("宽度:\t\t" + compoundStructureLayer.Width.ToString());
            }
            TaskDialog.Show("a", stringBuilder.ToString());

            Reference reference1 = uIDocument.Selection.PickObject(ObjectType.Element);
            Wall wall1 = doc.GetElement(reference1) as Wall;
            IList<ElementId> elementIds = wall1.FindInserts(true, true, true, true);

            StringBuilder stringBuilder1= new StringBuilder();
            foreach (var elementId in elementIds)
            {
                Element element = doc.GetElement(elementId) ;
                stringBuilder1.AppendLine("Id:\t\t" + elementId.ToString());
                stringBuilder1.AppendLine("类型名称:\t\t" + element.Name.ToString());
                
            }
            TaskDialog.Show("a", stringBuilder1.ToString());
            transaction.Commit();

            //

            return Result.Succeeded;
        }
    }
}

2.获取宿主元素上的其它元素如wall.FindInserts()

使用HostObject.FindInserts方法可以用来获取插入到宿主元素上的元素的集合：
IList<ElementId>FindInserts(bool addRectOpenings,bool includeShadows,boolincludeEmbeddedWalls,bool includeSharedEmbeddedInserts)

3.获取宿主的面，HostObjectUtils类的方法

4.创建墙

using Autodesk.Revit.DB;
using System.Collections.Generic;
using System.Linq;

namespace Revit_CreatInstane
{
    public static class WallFactory
    {
       
        public static ElementId CreateWall(Document document) 
        {
            //创建线
            XYZ start=new XYZ(0,0,0);
            XYZ end=new XYZ(10000/304.8, 0,0);
            Line line=Line.CreateBound(start, end);
            //创建标高
            List<Level> levels = document.SpeedFilter<Level>(BuiltInCategory.OST_Levels);

            Level level=levels.FirstOrDefault(x => x.Name == "标高 1");
            //高度
            double height = 4000.0.Unit();
            //is structural
            bool isStruct = true;
            //偏移量
            double offset = 0;

            //获取类型

            List<WallType> wallTypes = document.SpeedFilter<WallType>(BuiltInCategory.OST_Walls);

            WallType wallType = wallTypes.FirstOrDefault( x => x.Name == "常规 - 300mm");

            Wall wall = Wall.Create(document, line, wallType.Id, level.Id, height, offset, false, isStruct);
            ElementId elementId = wall.Id;
            return elementId;

            
        }
        
        
    }
}

5.创建楼板

            //Application类表示一个Revit应用，提供对文档、选项以及其他应用范围的数据的访问和设置。
            Application app = uIApplication.Application;

            UIDocument uIDocument = uIApplication.ActiveUIDocument;
            //用与存储Revit的元素、管理视图和数据
            Document doc = uIDocument.Document;

            //删除
            Transaction transaction = new Transaction(doc, "创建楼板");
            transaction.Start();

            Reference reference =uIDocument.Selection.PickObject(ObjectType.Element, new FloorSelectionFilter());

            Room room=doc.GetElement(reference) as Room;


            IList<IList<BoundarySegment>> a = room.GetBoundarySegments(new SpatialElementBoundaryOptions());

            CurveArray curveArray = new CurveArray();
            foreach (IList<BoundarySegment> boundarySegments in a)
            {
                foreach(BoundarySegment boundarySegment in boundarySegments)
                {
                    curveArray.Append(boundarySegment.GetCurve());

                }

            }
            
            FloorType floorType = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Floors).OfClass(typeof(FloorType)).FirstOrDefault() as FloorType;
            Level level = new FilteredElementCollector(doc).OfClass(typeof(Level)).FirstOrDefault() as Level;
            doc.Create.NewFloor(curveArray, floorType, level,false);

            TaskDialog.Show("测试",room.Name);
            
            transaction.Commit();

            //

            return Result.Succeeded;
        }

        {
            public bool AllowElement(Element elem)
            {
                
                if(elem is Room&&(!elem.Equals(null)))
                
                    return true;
                else
