Something I learned about plot sizes and placing imported plans.

So I was messing around checking out imported plans and like I always do i way over buying plot sizes and thought it would be nice to know the size they used.

So what you do is buy the standard plot size 2x2 2x2 2x2 and import your station of choice, most of them need plots way bigger as you can tell as soon as you import them.
Confirm the build then go back into the plot buying tab and it will be the correct size just move one of the plot sizes and it pops up with the new price and you can buy it and your plot will be the perfect size.

I am not sure if this is the spot for it but it should be posted somewhere for others to see.

Is also seems you can go back any time and make your plots bigger. Can't seem to shrink the overly large ones but not I don't have to worry about not having growing room and can expand the plot as needed.

I was just thinking of the plot size problem.
I think it would be nice if the OP tells what it is for there submission.
But this trick (i have not tested it yet) is a great fix!
