I’ve had a few people ask me recently why they can’t copy Doors from one wall to another. I was surprised they couldn’t as I could without any issues. But then something clicked…the Constrain checkbox. Sure enough, if Constrain is checked, you can’t copy a Door outside of the wall it’s placed in. So in order to copy the door from one wall to another by utilizing the Copy tool, just make sure the Constrain checkbox is unchecked.
Or, just utilize a right-click and Create Similar.
