Question about door frames

Hej
I have a question on some of the designs,
first the  "Computer_1"  are any Garage door parts of that intended to operate?
I cant get any of them to trigger. 
It would be really cool if one or some of the doors or the Giant red door could open.
 I can see trigger boxes when in vanish moode but I dont know if its supposed to be possible to open the doors or not? 

Also the main entrance on Computer_1   is that intended to have a snappable area to attach a door? 
as doors cant be snapped on.

For Example the functional garage door on  "Castle_3_Adobe"  or the snappable door area on some of the entrances of "Castle_2"
where a player can snap and place a standard 1 frame door in two of the entrances.


Thanks for any info
