本文演示Revit中梁的创建。

实例代码：

using Autodesk.Revit.Attributes;
    using Autodesk.Revit.DB;
    using Autodesk.Revit.DB.Structure;
    using Autodesk.Revit.UI;
    
    namespace RevitAddin4
    {
        [TransactionAttribute(TransactionMode.Manual)]
        public class RevitAddin : IExternalCommand
        {
            public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
            {
                UIDocument uiDoc = commandData.Application.ActiveUIDocument;
                Document doc = uiDoc.Document;
                FilteredElementCollector collector = new FilteredElementCollector(doc);
                collector.OfCategory(BuiltInCategory.OST_StructuralFraming);
                FamilySymbol familySymbol = null;
                foreach (var item in collector)
                {
                    familySymbol = item as FamilySymbol;
                    if (familySymbol != null)
                        break;
                }
                //创建线
                Curve curve = Line.CreateBound(new XYZ(0, 0, 0), new XYZ(0, 20, 0));
                //获取当前视图的标高
                Level level = doc.ActiveView.GenLevel;
                if (level == null)
                {
                    TaskDialog.Show("错误", "不是PlainView");
                    return Result.Failed;
                }
                //创建梁
                using (Transaction tr = new Transaction(doc))
                {
                    tr.Start("Create beam");
                    if(!familySymbol.IsActive)
                        familySymbol.Activate();
                    doc.Create.NewFamilyInstance(curve, familySymbol, level, StructuralType.Beam);
                    tr.Commit();
                }
                return Result.Succeeded;
            }
        }
    }

运行结果：
