Revit二次开发-1

引用RevitAPI.dll和RevitAPIUI.dll
1、Revit外部命令

namespace HelloRevit
{
    /*添加外部命令*/
    [Autodesk.Revit.Attributes.Transaction(
        Autodesk.Revit.Attributes.TransactionMode.Manual)]
    public class Class1:IExternalCommand
    {
        public Autodesk.Revit.UI.Result Execute(
                        ExternalCommandData revit, 
                        ref string message, ElementSet elements)

        {
            TaskDialog.Show("Revit", "Hello World");
            return Autodesk.Revit.UI.Result.Succeeded;
        }
    }
}

2、添加选项卡

public class CsAdd:Autodesk.Revit.UI.IExternalApplication
    {
        public Autodesk.Revit.UI.Result OnStartup(UIControlledApplication application)
        {
            RibbonPanel ribPanel = application.CreateRibbonPanel("NewRibbonPanel");
            PushButton pBtn = ribPanel.AddItem(new PushButtonData("HelloRevit",
                "HelloRevitPan", @"[路径]\HelloRevit.dll",
                "HelloRevit.Class1")) as PushButton;
            Uri uriImg = new Uri(@"[路径]\logo.ico");
            BitmapImage largeImage = new BitmapImage(uriImg);
            pBtn.LargeImage = largeImage;
            return Result.Succeeded;
        }
        public Result OnShutdown(UIControlledApplication application)
        {
            return Result.Succeeded;
        }
    }
