Hello Mrs. Zeliha, we did not remove the separate selection of the doors and windows, on the contrary, we just made it, so now the doors and windows can be selected separately. The other issue is to separate the layers just to close the doors or just the windows. It is helpful if the program separates the layers. Then, as you wish, you will have automatic options such as closing the layer of the doors, only locking the windows. You can separate the layers yourself for now. For example, create a new layer named door. Choose a door that you have drawn and say select them all. Only your doors are selected. Enter the Change object layer command and select the newly created door layer from the list. When you close the door layer from the layer list, only your windows will appear.
