revit二次开发-创建族

通过文件路径载入族

并点击任意一点创建实例

 代码如下：

using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.DB.Structure;
using Autodesk.Revit.UI;
using System;
using System.Collections.Generic;
using System.IO;

using System.Text;
using System.Threading.Tasks;

        UIApplication uIApplication = null;
        Document document = null;
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {

            UIApplication uiApp = commandData.Application;
            uIDocument = uiApp.ActiveUIDocument;
            uIApplication = uIDocument.Application;
            document = uIDocument.Document;


            using (Transaction transaction = new Transaction(document, "创建族"))
            {

                transaction.Start();

                FamilyInstance familyInstance = CreateFamilyInstance();

                transaction.Commit();
                TransactionStatus status = transaction.GetStatus();
                if (status.Equals(TransactionStatus.Committed))
                {
                    TaskDialog.Show("提示", "创建成功！");             
                }
            }
            return Result.Succeeded;

        }
