04.Revit2016二次开发（基础篇）——生成单个轴网

趁着昨天用Python在Dynamo中实现生成一个轴网；今天我尝试了用C#来实现；
我首先根据书上所说的方法（当然，API已经过期）：

using(Transaction transcation = new Transcation(doc))
{
      transaction.Start("Create Grid");
      Grid grid = RevitDoc.Create.NewGrid(
Line.CreateBound(new XYZ(0,0,0), new XYZ(10,10,0)));
      grid.Name = "BB";
      transcation.Commit();
}

查询了API，发现API已经发生了变化：

NewGrid方法已经Obsolete

于是我在索引中输入Grid，找到Grid Class的Members:

Grid Members

我发现这个类中有方法Create方法，这是一个重载函数，若想生成轴网，就传入两个参数，分别是doc和Line；

那么这就很简单了：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Autodesk.Revit.DB;
using Autodesk.Revit.UI;
using Autodesk.Revit.ApplicationServices;
using Autodesk.Revit.Attributes;
using System.Windows.Forms;
using Application = Autodesk.Revit.ApplicationServices.Application;

//messeageBox;



namespace Revit
{
    [Transaction(TransactionMode.Automatic)]
    [Regeneration(RegenerationOption.Manual)]
    public class ArgumentUsage : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            UIApplication uiApplication = commandData.Application;
            Application application = uiApplication.Application;
            UIDocument uiDocument = uiApplication.ActiveUIDocument;
            Document doc = uiDocument.Document;


            using (Transaction trans = new Transaction(doc))
            {
                trans.Start("Create Grid");
                Line line = Line.CreateBound(new XYZ(0, 0, 0), new XYZ(10, 10, 0));
                Grid grid = Grid.Create(doc, line);
                grid.Name = "A";
                trans.Commit();
            }
            return Result.Succeeded;
        }
    }
}

效果图：

总结：

• 还是那句话，API总在变，可是实现的方法逻辑不会改变，思路永远是最重要的；

• 我还发现，使用ADD-In Manager的时候，要用Manual Mode方式运行，关于Manual和AutoMatic Mode我还是有点不懂。。。
