Hello, For some reason Revit API does not allow to close an **ActiveUIDocument** , and I know is possible to close using press **F4** or **PostCommand.Close**. I want to share a different approach using **UIFramework** reference. Here is the extension for the **UIApplication** to enable **CloseAllUIDocument **and **CloseActiveUIDocument**. * https://gist.github.com/ricaun/ff6814faf407ee044b93ee8e787f628c Basically the code close UI document window and use the event **DialogBoxShowing **to force to save or not the document if the save popup happens. Here is a simple Command to close the **ActiveUIDocument**. [Transaction(TransactionMode.Manual)] public class CommandCloseActiveUIDocument : IExternalCommand { public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elementSet) { UIApplication uiapp = commandData.Application; uiapp.CloseActiveUIDocument(); return Result.Succeeded; } } To use the extension your project need to have the **UIFramework  **reference, you can add the reference using the packages below. <PackageReference Include="Revit_All_Main_Versions_API_x64" Version="$(RevitVersion).*" IncludeAssets="build; compile" PrivateAssets="All" /> or <PackageReference Include="Nice3point.Revit.Api.UIFramework" Version="$(RevitVersion).*"/> See yaa!
