         Application.DocumentManager.MdiActiveDocument.SendStringToExecute(ctl.CommandParameter.ToString().TrimEnd() + " ", true, false, false);
     }
 }

调用方法

 var cmds = CMDHelper.GetAssemblyAutoCADCmds(ass);
 var assName= ass.GetName().Name; 
  MyRibbonTab myRibbonTab = new MyRibbonTab(cmds, assName, assName);

效果如下
