Hello, in the project I sent attached, I can see the door and window openings in the plan, but not in the views. I would like your help as to where I went wrong. Let me briefly describe the project; It will be a single storey boiler room building. There will be 50 cm foundation, 70 cm basement and 550 cm floor height. I defined the sub-basement curtains under the walls as normal curtains and lowered the level to obtain 70 cm. I did it by adding 70 cm to the defined elevation values of the program when placing doors and windows. thanks everyone
