Revit2016 二次开发笔记1.选中图元1.1事先选择某类图元（Wall）Autodesk.Revit.UI.UIApplication revit = commandData.Application;ElementSet collection = new ElementSet();ElementSet selWall = new ElementSet();foreach (ElementId elementId in revit.ActiveUIDocument.Selection.GetElementIds()){collection.Insert(revit.ActiveUIDocument.Document.GetElement(elementId)); //选中的原件}foreach (Element ele in sel){Wall wall = ele as Wall; //如果为墙if (wall !=null){SelWal.Insert(ele);}}1.2.通过交互方式1.2.1用矩形框选择图元所用方法：PickElementsByRectangle()using System.Collections.Generic; //声明引用命名空间，IlistUIDocument uidoc = commandData.Application.ActiveUIDocument;ElementSet collector = new ElementSet();IListElement elemList = uidoc.Selection.PickElementsByRectangle();//矩形框的应用string info = 所选图元：;foreach (Element elem in elemList){collector.Insert(elem);info += \n\t + elem.ToString();}TaskDialog.Show(Choose Items, info);return Result.Succeeded;1.2.2用点击选择图元所用方法：PickObject(ObjectType.Element)using Autodesk.Revit.UI.Selection; //声明引用命名空间，ObjectTypeUIDocument uidoc = commandData.Application.ActiveUIDocument;Reference hasPickOne = uidoc.Selection.PickObject(ObjectType.Element);Element elem = uidoc.Document.GetElement(hasPickOne.ElementId);string info = 所选图元：;info += \n\t + elem.GetType().ToString();TaskDialog.Show(Revit, info);还存在其它用法：Selection.PickObject (ObjectType, String) //string 为提示 PickObjects (ObjectType) //允许选择多个元素1.2.3选择及过滤UIDocument uidoc = commandData.Application.ActiveUIDocument;ISelectionFilter selFilter = new MassSelectionFilter();IListElement eList = uidoc.Selection.PickElementsByRectangle(selFilter) as IListElement;string info = 选择了以下的墙：;foreach(Element elem in eList){info += \n\t + elem.Name;}TaskDialog.Show(Revit, info);return Result.Succeeded;public class MassSelectionFilter : ISelectionFilter{public bool AllowElement(Element elem){return elem is Wall; //选择了墙}public bool AllowReference(Reference reference, XYZ position){throw new NotImplementedException();// 第二个条件}}2.加载族并创建实例UIApplication m_applica
