Almost appears as if the door Spock comes through is on the opposite side than in the set plan. Where it says "console" beside the word "forward" above the word "see" is where the door ended up being put for shooting.
He walks in, the engineering grill is on his right. The camera would be around where the word "dwg" is. The sitdown console is rotated 90 degrees, you're right about that.
If you follow the set plan, the grill would be on his left if he walked in the door that's shown - it's not accurate. I figure that when they got to shooting, it blocked better the way it ended up in the episode.
