实例练习二

using System.Linq;
using System.Text;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.ApplicationServices;
using Autodesk.Revit.Attributes;

using Autodesk.Revit.UI.Selection;

namespace RevitDevTV
{
    /// <summary>
    /// 尝试不同类型元素的创建方法
    /// </summary>
    [TransactionAttribute(TransactionMode.Manual)]
    [RegenerationAttribute(RegenerationOption.Manual)]
    public class MoreCreation : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            UIDocument uidoc = commandData.Application.ActiveUIDocument;
            Document doc = uidoc.Document;
            Transaction trans = new Transaction(doc, "LS");
            trans.Start();
            Curve c1 = Line.CreateBound(new XYZ(0, 0, 0), new XYZ(0, 10, 0));
            Curve c2 = Line.CreateBound(new XYZ(0, 10, 0), new XYZ(10, 10, 0));
            Curve c3 = Line.CreateBound(new XYZ(10, 10, 0), new XYZ(10, 0, 0));
            Curve c4 = Line.CreateBound(new XYZ(10, 0, 0), new XYZ(0, 0, 0));
            CurveArray curveArray = new CurveArray();
            curveArray.Append(c1);
            curveArray.Append(c2);
            curveArray.Append(c3);
            curveArray.Append(c4);
            CurveArrArray curveArr = new CurveArrArray();
            curveArr.Append(curveArray);
            //图形的拉伸创建
            doc.FamilyCreate.NewExtrusion(true, curveArr, SketchPlane.Create(doc, Plane.CreateByOriginAndBasis(new XYZ(20, 20, 20), new XYZ(20, 20, 20),new XYZ(20, 20, 20))), 10);
            doc.FamilyManager.NewType("我创建的类");
            trans.Commit();
            return Result.Succeeded;
        }
    }
}

这块Plane.CreateByOriginAndBasis(new XYZ(20, 20, 20), new XYZ(20, 20, 20),new XYZ(20, 20, 20))有问题，功能没实现
