Revit二次开发之创建房间,根据房间边界创建楼板等

以前就已经对创建房间有过了解,只是点到为止没有进一步的深究下去,今天有点时间就整理一下思路,留着以后备用。其实创建完房间后,可以算房间面积,空间体积什么的,也可以获得房间的边界线去做一些工作,比如生成楼板,墙踢脚线,墙饰条等等,其实原理都一样就是利用房间的闭合曲线!

 

首先来一个批量创建房间的代码,这里就只写步骤了,不拷贝整个工程了

 

  UIApplication uiApp = commandData.Application;

  UIDocument uidoc = uiApp.ActiveUIDocument;

  Document doc = uidoc.Document;

  ViewPlan view = uidoc.ActiveView as ViewPlan;

 Transaction ts = new Transaction(doc, "BIM");

            ts.Start();

         

                Level level = uidoc.ActiveView.GenLevel;

                PlanTopology pt = doc.get_PlanTopology(level);

                foreach (PlanCircuit pc in pt.Circuits)

                {

                    if (!pc.IsRoomLocated)

                    {

                        Room newRoom = doc.Create.NewRoom(null, pc);

                        LinkElementId elemid = new LinkElementId(newRoom.Id);

                        Location location = newRoom.Location;

                        LocationPoint locationPoint = location as LocationPoint;

                        XYZ point3d = locationPoint.Point;

                        UV point2d = new UV(point3d.X, point3d.Y);

                        RoomTag roomTag = doc.Create.NewRoomTag(elemid, point2d, view.Id);

                        if (family != null)

                        {

                            try

                            {

//这里的symbol其实是自定义的一个房间标记族,可以自行导入,这里就不再介绍了

                                FamilySymbol symbol = family.Document.GetElement(family.GetFamilySymbolIds().First()) as FamilySymbol;

                                if (symbol != null)

                                {

                                    roomTag.ChangeTypeId(symbol.Id);

                                }

                            }

                            catch { }

                        }

                    }

                }

 

                ts.Commit();

         

以上代码就是批量生成房间的代码段,接下来就是获得房间边界生成楼板,不过在此之前我们先看看每个房间边界的样子,我们可以根据Room.GetBoundarySegments()方法来获得 IList<>集合,根据这个集合去遍历所有的房间边界,在此之前我们还需要一个SpatialElementBoundaryOptions选项,它给我们提供了SpatialElementBoundaryLocation枚举类型,公有四个,分别是,Center,CoreBoundary,CoreCenter,finish,那么分别是什么意思呢,查阅一下RevitAPI帮助文档后得知:

1.Center,这里可以理解为墙的中心线

2.CoreBoundary,这里可以理解为墙的核心层边界线

3.CoreCenter,这里可以理解为墙的核心层中心线

4,.Finish.这里可以理解为墙的面层

上述翻译有可能不太准确,希望读者自行实验判断吧,接下来我们实测一下这四个选项,我的思路是根据房间的边界线生成详图线用以观察四个选项的区别,为了明显起见我想自定义一个线样式,宽度为1个单位,颜色为红色,主要代码如下:

 

 ////生成线样式

                using (Transaction ts = new Transaction(doc, "LineStyle"))

                {

                    ts.Start();

                    Category lineCategory = doc.Settings.Categories.get_Item(BuiltInCategory.OST_Lines);

                    Category newCategory = doc.Settings.Categories.NewSubcategory(lineCategory, "房间边界线");

                    Color newColor = new Color(255, 0, 0);

                    newCategory.LineColor = newColor;

                    newCategory.SetLineWeight(1, GraphicsStyleType.Projection);

                    ts.Commit();

                }

 

生成之后的系统线样式下:

好了 那么接下来我们就可以过滤房间边界来看一看它们的样子:核心代码,记得开启事务

 

           //这里拾取一个房间,为了简便没有加过滤器限制

            Reference refer = uidoc.Selection.PickObject(ObjectType.Element, "");

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

            SpatialElementBoundaryOptions opt = new SpatialElementBoundaryOptions();

            opt.SpatialElementBoundaryLocation = SpatialElementBoundaryLocation.Center;

           //声明的Curve集合是为创建楼板而服务的

            CurveArray array = new CurveArray();

          IList(IList(BoundarySegment)) loops = room.GetBoundarySegments(opt);

            foreach (IList(BoundarySegment) loop in loops)

            {

                foreach (BoundarySegment seg in loop)

                {

                    Curve curve = seg.GetCurve();

                    //创建详图线,设置它的线样式类型为我们刚才创建的

                    DetailCurve dc = doc.Create.NewDetailCurve(uidoc.ActiveView, curve);

                    if (BackLineStyle(doc) != null)

                    {

                        SetLineStyle(BackLineStyle(doc), dc);

                    }

                    array.Append(dc.GeometryCurve);

                }

            }

                 

  //两个相关的方法

 //搜索目标线样式

        private Category BackLineStyle(Document doc)

        {

            Category lineCategory = doc.Settings.Categories.get_Item(BuiltInCategory.OST_Lines);

            CategoryNameMap map = lineCategory.SubCategories;

            foreach (Category g in map)

            {

                if (g.Name == "房间边界线")

                {

                    return g;

                }

            }

            return null;

        }

  //设置线样式

        private void SetLineStyle(Category cate, DetailCurve line)

        {

            ElementId Id = new ElementId(cate.Id.IntegerValue + 1);

 

            foreach (Parameter p in line.Parameters)

            {

                if (p.Definition.Name == "线样式")

                {

                    p.Set(Id);

                    break;

                }

            }

        }

上述代买我们用的是Center选项,让我们来看看效果:

红色是房价你的边界线的路径,可以看得出与墙中心线重合,我使用的墙结构信息如下:

改变Center选项为Finish后,我们再看看效果:

其他两个选项,读者自行分析吧,这里就不再介绍了:

接上述代码获得房间边界,我们可以创建楼板,以下为核心代码:

 //创建楼板,类型默认 标高默认

        private void CreateFloor(Document doc,CurveArray array)

        {

            FloorType floorType= new FilteredElementCollector(doc).OfClass(typeof(FloorType)).FirstOrDefault() as FloorType;

            Level level = new FilteredElementCollector(doc).OfClass(typeof(Level)).OrderBy(o => (o as Level).ProjectElevation).First() as Level;

            Floor floor = doc.Create.NewFloor(array,floorType,level,false,XYZ.BasisZ);

        }

生成楼板(其实根据闭合曲线能创建很多东西,也可以用其做族的放样,生成散水,踢脚线等,有时间我会写一个创建族的基本流程)之后的局部三维视图如下:
