Hi @fabrice c101 thanks for posting in the community! If you are using our floor plan shapes you should be able to move the door shape and it will automatically snap to the wall you are trying to add to. It is also possible to move the door and change the direction it opens. This community post demonstrates some of these features which I highly recommend checking out!

Please let me know if that is not what you are looking for and I would be happy to assist further. Thank you! :) 

Thanks Leianne for your help with the matter.
