The first solution requires to have multiple models of the same door or window for different wall thicknesses. This is what is used for the doors in this library. Almost every door is available in multiple versions for different wall thicknesses. You can select the correct door for the thickness of your wall by using a keyword to filter: W10, W15, W20, or W30. The number is the wall thickness in cm. If you have your catalog set to a searchable list this makes it easy to filter all doors that match your wall thickness.
