Revit二次开发小案例之喷头与管道自动连接
思路分享如下：
使用鼠标框选需要连接的喷头，当然也可以不框选，这里框选是为了方便。
PTFamilyInstance f = new PTFamilyInstance();IList<Element> ell = sel.PickElementsByRectangle(f,"请选择要连接的喷头");
这里是一个过滤筛选的写法，不会的小伙伴再看一下
public class PTFamilyInstance : ISelectionFilter{public bool AllowElement(Element element){if (element.Category.Name == "喷头"){return true;}return false;}public bool AllowReference(Reference refer, XYZ point){return false;}}
2.为了加快筛选的效率，小编使用了喷头的范围框进行筛选
小编的这个喷淋有2种喷头，直立型和下垂型，因此范围框筛选有两种方式，代码如下：
if (co.IsConnected == false){conn1.Add(co);BoundingBoxXYZ box = eel.get_BoundingBox(doc.ActiveView);//用喷头的范围框快速过滤double Maxx = box.Max.X;double Maxy = box.Max.Y;double Minx = box.Min.X;double Miny = box.Min.Y;double MZz = box.Max.Z;Outline myOutLn = null;if (eel.GetParameters("族与类型")[0].AsValueString().Contains("直立型")){myOutLn = new Outline(new XYZ(Minx, Miny, MZz - (50 / 304.8)), new XYZ(Maxx, Maxy, MZz - (50 / 304.8)));}else{myOutLn = new Outline(new XYZ(Minx, Miny, MZz + (50 / 304.8)), new XYZ(Maxx, Maxy, MZz + (50 / 304.8)));}//用喷头的范围框过滤管道BoundingBoxIntersectsFilter boxee = new BoundingBoxIntersectsFilter(myOutLn);FilteredElementCollector collector = new FilteredElementCollector(doc, doc.ActiveView.Id);collector.OfClass(typeof(Pipe));pipe1 = collector.WherePasses(boxee).ToElements();//与喷头范围框相交的管道
3. 获取连接器，将管道与喷头连接
foreach (Element elp in pipe1){Pipe pp = elp as Pipe;ConnectorSetIterator ppconn = pp.ConnectorManager.Connectors.ForwardIterator();while (ppconn.MoveNext()){Connector ppconn2 = ppconn.Current as Connector;if (ppconn2.IsConnected == false){ppconnlist.Add(ppconn2);try{//doc.Create.NewUnionFitting(ppconn2, co);doc.Create.NewTransitionFitting(ppconn2, co);}catch{}}}}
这里小编试了一下使用，如下这两种方法都可以实现连接。
doc.Create.NewUnionFitting(ppconn2, co);doc.Create.NewTransitionFitting(ppconn2, co);
Selection sel = uiDoc.Selection;List<ElementId> listt = new List<ElementId>();PTFamilyInstance f = new PTFamilyInstance();IList<Element> ell = sel.PickElementsByRectangle(f,"请选择要连接的喷头");IList<Connector> conn1 = new List<Connector>();IList<Connector> ppconnlist = new List<Connector>();IList<Element> pipe1 = new List<Element>();foreach (Element eel in ell){FamilyInstance fa = eel as FamilyInstance;ConnectorSetIterator connector1 = fa.MEPModel.ConnectorManager.Connectors.ForwardIterator();while (connector1.MoveNext()){Connector co = connector1.Current as Connector;if (co.IsConnected == false){conn1.Add(co);BoundingBoxXYZ box = eel.get_BoundingBox(doc.ActiveView);//用喷头的范围框快速过滤double Maxx = box.Max.X;double Maxy = box.Max.Y;double Minx = box.Min.X;double Miny = box.Min.Y;double MZz = box.Max.Z;Outline myOutLn = null;if (eel.GetParameters("族与类型")[0].AsValueString().Contains("直立型")){myOutLn = new Outline(new XYZ(Minx, Miny, MZz - (50 / 304.8)), new XYZ(Maxx, Maxy, MZz - (50 / 304.8)));}else{myOutLn = new Outline(new XYZ(Minx, Miny, MZz + (50 / 304.8)), new XYZ(Maxx, Maxy, MZz + (50 / 304.8)));}//用喷头的范围框过滤管道BoundingBoxIntersectsFilter boxee = new BoundingBoxIntersectsFilter(myOutLn);FilteredElementCollector collector = new FilteredElementCollector(doc, doc.ActiveView.Id);collector.OfClass(typeof(Pipe));pipe1 = collector.WherePasses(boxee).ToElements();//与喷头范围框相交的管道foreach (Element elp in pipe1){Pipe pp = elp as Pipe;ConnectorSetIterator ppconn = pp.ConnectorManager.Connectors.ForwardIterator();while (ppconn.MoveNext()){Connector ppconn2 = ppconn.Current as Connector;if (ppconn2.IsConnected == false){ppconnlist.Add(ppconn2);try{//doc.Create.NewUnionFitting(ppconn2, co);doc.Create.NewTransitionFitting(ppconn2, co);}catch{}}}}}}}
