Revit二次开发之“墙体开洞NewOpening”

墙体开洞的函数是Document.Create.NewOpening(Wall,XYZ,XYX);

但是这里有个技巧就是如何选取墙上的两点。

添加一个墙的过滤条件。

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;



using WinForm = System.Windows.Forms;



using Autodesk.Revit.UI;

using Autodesk.Revit.DB;

using Autodesk.Revit.Attributes;



using Autodesk.Revit.DB.Mechanical;

using Autodesk.Revit.UI.Selection;

using RevitApp = Autodesk.Revit.ApplicationServices;



using System.Xml;



namespace RevitCodes

{

    class WallSelectionFilter : ISelectionFilter

    {

        public bool AllowElement(Element e)

        {

            return e is Wall;

        }



        public bool AllowReference(Reference r, XYZ p)

        {

            return true;

        }

    }

    [Transaction(TransactionMode.Manual)]

    [Regeneration(RegenerationOption.Manual)]

    public class cmdCreateOpening : IExternalCommand

    {

        public Result Execute(ExternalCommandData cmdData, ref string msg, ElementSet elements)

        {

            UIApplication uiApp = cmdData.Application;

            Document doc = uiApp.ActiveUIDocument.Document;

            Selection sel = uiApp.ActiveUIDocument.Selection;



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

            ts.Start();



            Wall wall = doc.GetElement(sel.PickObject(ObjectType.Element, "请选择一面墙。")) as Wall;

            WallSelectionFilter f = new WallSelectionFilter();

            XYZ pt1 = sel.PickObject(ObjectType.Element, f, "请选择墙上第一点。").GlobalPoint;

            XYZ pt2 = sel.PickObject(ObjectType.Element, f, "请选择墙上第二点。").GlobalPoint;



            doc.Create.NewOpening(wall, pt1, pt2);



            ts.Commit();



            return Result.Succeeded;

        }

    }

}
