Interior Doors (X3)

[jonathank]

I have a question on interior doors. This might have been brought up in the past (if it has I apologize).

My question is:
How come CA will sometime drop a door in a wall that will go from wall to wall
(not allowing for framing/trim/shims/etc...), and sometimes it will make the door
smaller to allow for that stuff?

Since I've been doing this for 4 years, it's second nature for me to just fix the
door right away. But we've hired another person to help with drafting, and it's
not as obvious to them as it is to the rest of us.

I've attached a plan to better clarify my question. All the doors I'm showing on
the plan are the default to what CA dropped in.

Thanks for the help...
