Command用のModuleをつくる

• ClassにIExternalCommandをつける
• Functionの引数にUIDocumentをいれる

using Autodesk.Revit.DB;
using Autodesk.Revit.UI.Selection;
using System.Collections.Generic;
using System.Linq;

	{
    	public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            myButtonMacro(commandData.Application.ActiveUIDocument);
            return Result.Succeeded;
        }

		#endregion
		
		public void myButtonMacro(UIDocument uidoc)

			//var uidoc = this.ActiveUIDocument;
			//hello world!
			TaskDialog.Show("Title","Hello World!");
			var doc = uidoc.Document;
			var walls = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Windows).ToElementIds();
