3.View 继承结构

所有的视图都是继承自 Autodesk.Revit.DB.View，分别对应各种视图类型

 

4.View 的实例

以官方给的文件为例：

楼层平面：ViewPlan
三维视图：View3D
立面、剖面、详细视图：ViewSection
渲染：ImageView
图例：View
明细表：ViewSchedule
图纸：ViewSheet

5.获取 View 的信息

视图的基本信息，包括:

视图名称，view.Name
视图裁剪区域，view.CropBox
视图起始点，view.Origin
视图平面投影区域，view.Outline
视图往右、往上、指向观察者的方向，view.RightDirection，view.UpDirection，view.ViewDirection
视图缩放比例，view.Scale

方法示例：

        private void Getinfo_View(Autodesk.Revit.DB.View view)
        {
            string message = "View: ";

            // 得到视图的名称
            message += "\nView name: " + view.Name;

            // 视图裁剪区域包围盒
            BoundingBoxXYZ cropBox = view.CropBox;
            XYZ max = cropBox.Max; // 最大值，包围盒右上角
            XYZ min = cropBox.Min; // 最小值，包围盒左下角
            message += "\nCrop Box: ";
            message += "\nMaximum coordinates: (" + max.X + ", " + max.Y + ", " + max.Z + ")";
            message += "\nMinimum coordinates: (" + min.X + ", " + min.Y + ", " + min.Z + ")";


            // 视图的起始点（想象一下透视视图）
            XYZ origin = view.Origin;
            message += "\nOrigin: (" + origin.X + ", " + origin.Y + ", " + origin.Z + ")";


            //视图投影到平面的范围框
            BoundingBoxUV outline = view.Outline;
            UV maxUv = outline.Max; // 最大值，包围盒右上角
            UV minUv = outline.Min; // 最小值，包围盒左下角
            message += "\nOutline: ";
            message += "\nMaximum coordinates: (" + maxUv.U + ", " + maxUv.V + ")";
            message += "\nMinimum coordinates: (" + minUv.U + ", " + minUv.V + ")";

            // 视图往右的方向
            XYZ rightDirection = view.RightDirection;
            message += "\nRight direction: (" + rightDirection.X + ", " +
                           rightDirection.Y + ", " + rightDirection.Z + ")";

            // 视图往上的方向
            XYZ upDirection = view.UpDirection;
            message += "\nUp direction: (" + upDirection.X + ", " +
                           upDirection.Y + ", " + upDirection.Z + ")";

            // 视图指向观察者（即我）的方向
            XYZ viewDirection = view.ViewDirection;
            message += "\nView direction: (" + viewDirection.X + ", " +
                           viewDirection.Y + ", " + viewDirection.Z + ")";

            // 视图的缩放比例
            message += "\nScale: " + view.Scale;
            // Scale is meaningless for Schedules
            if (view.ViewType != ViewType.Schedule)
            {
                int testScale = 5;
                //设置视图比例，需要 Transaction
                view.Scale = testScale;
                message += "\nScale after set: " + view.Scale;
            }

            TaskDialog.Show("Revit", message);
        }

主程序调用：

using System;
using System.Collections.Generic;
using System.Text;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;

namespace PersonalTools
{
    [Transaction(TransactionMode.Manual)]
    public class Command : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            UIApplication uiApp = commandData.Application;
            UIDocument uiDoc = uiApp.ActiveUIDocument;
            Document doc = uiDoc.Document;

            using(Transaction transaction = new Transaction(doc, "View"))
            {
                transaction.Start();
                View view = doc.ActiveView;
                Getinfo_View(view);
                transaction.Commit();
            }
            return Result.Succeeded;
        }

前视图数据：可知 Revit 中的坐标系，往右是 X 方向，往上是 Z 方向。因此前视图是从 Y 方向从屏幕外指向屏幕里面。
