Oolite Bulletins

Thank you everyone for the super-fast responses! I very much enjoy playing oolite and look forwards to designing a ship for myself.

But couldn't I change the dimensions of a current model (from an add on oxp)? thanks again for your input. Also, what is the easiest way for a new ship designer to design a ship?

I am new to oolite. How does one change a ships size (exterior dimensions) from an .oxp? sounds like cheating, but i am starting with modifying existing oxp's before designing my own. thank you for any input.
