This command Updates (or Refreshes) Selected Turnouts, Sectional Tracks and Structures on your layout with definitions from the loaded Parameter Files. Each object that is found in a Parameter File is updated with the current definition.
If an object can not be found or if the new definition does not fit (same number of End-Points and all the End-Points have the same position and angle) then a dialog is displayed which contains suitable definitions that you can choose from. You can Skip the current object or Cancel to skip all the remaining objects.
If an object has been Updated then it is Unselected, otherwise it will remain Selected at the end of this command.
