Revit无法运行外部命令
Revit无法运行外部命令
提问于 2018-08-08 15:25:05
我目前正在尝试创建一个Autodesk加载项，用于检查房间的几何形状。我很难做到这一点，原因是出现了一个错误："Revit不能运行外部命令。AutodeskRevit.Exceptions.InvalidOperationException. HelloWorld.Class1不继承IExternalCommand。
抱歉，我是C#和Autodesk Revit的新手
因此，我假设需要将IExternalCommand输入到代码中来运行命令。当我这样做包括IExternalComand时，我会收到一个visual错误，上面写着"Class1不实现接口成员IExternalComand ref string，ElementSet)“。
这是我的代码：
using System;
using Autodesk.Revit.UI;
using Autodesk.Revit.DB;
using Autodesk.Revit.ApplicationServices;
using Autodesk.Revit.Attributes;
using Autodesk.Revit.Creation;
using Autodesk.Revit.Exceptions;
using Autodesk.Revit.DB.Architecture;
namespace HelloWorld
{
[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]
[Autodesk.Revit.Attributes.Regeneration(Autodesk.Revit.Attributes.RegenerationOption.Manual)]
class Class1 :IExternalCommand
{
public void GetRoomDimensions(Autodesk.Revit.DB.Document doc, Room room)
{
String roominfo = "Room dimensions:\n";
// turn on volume calculations:
using (Transaction t = new Transaction(doc, "Turn on volume calculation"))
{
t.Start();
AreaVolumeSettings settings = AreaVolumeSettings.GetAreaVolumeSettings(doc);
settings.ComputeVolumes = true;
t.Commit();
}
roominfo += "Vol: " + room.Volume + "\n";
roominfo += "Area: " + room.Area + "\n";
roominfo += "Perimeter: " + room.Perimeter + "\n";
roominfo += "Unbounded height: " + room.UnboundedHeight + "\n";
TaskDialog.Show("Revit", roominfo);
}
}
}谢谢你的建议。

IExternalCommand从Execute方法运行。您需要在类中定义一个Execute方法。在那里您可以调用您的GetRoomDimensions方法
public Result Execute(
ExternalCommandData commandData,
ref string message,
ElementSet elements)
{
UIApplication application = commandData.Application;
Document mainDocument = application.ActiveUIDocument.Document;
if(elements.Size > 0)
{
//Only 1 room should be selected
return Result.Failed;
}
Room room = null;
foreach(Element element in elements)
{
room = element as Room;
}
if(room == null)
{
//A non-room element was selected
return Result.Failed;
}
GetRoomDimensions(mainDocument, room);
return Result.Success
