revit二次开发API示例 命令替换

应用程序：DisableCommand

Revit平台：所有版本

Revit版本：2013.0

首次发布版本：2013.0

编程语言：C#

技能水平：初学者

类别：基础知识

类型：外部应用程序

主题：命令替换

摘要：通过替换其实现为简单的弹出消息来禁用命令

相关类:

Autodesk.Revit.UI.IExternalApplication

Autodesk.Revit.UI.RevitCommandId

Autodesk.Revit.UI.AddInCommandBinding

Autodesk.Revit.UI.UIControlledApplication

项目文件：

Application.cs

外部应用程序

功能：

此示例重写了“构建选项(B)"命令，以防止用户访问它。

查找RevitCommandId以匹配命令的日志名称。

为此命令ID创建AddInCommandBinding。

为命令绑定提供替代实现。

实施：

打开 Revit。

打开或创建一个项目。

选择 Manage 选项卡上的 Design Options 按钮。

一个弹出窗口会解释该命令已被禁用。
