Problems with basic geometry in OPENSTUDIO

edit

Hello! someone knows how to resolve this problem? OS doesn't allow me to complete a space (geometry). When I try to draw the last space the program separetes automatically with other spaces.

UPDATE

Hello @Julien Marrec! Thanks a lot for your reply. Your video is exactly what I need to make (in the same order), but when I try to draw the last space (space 1-5 in your video) the program makes automatically what is in the second PrintScreen sent. It means that OS separates space 1-1 (in your video) from other spaces. If I try to draw in different manners the program joins or separates randomly. Finally, I can not draw the last space together with the other ones, as you did it. I have I little video link below.
