I draw a quick sketch on a drawing software then let computer do the calculation.
This method get better result than just use auto hinge align tools in many case.
Make LDD model as perfect as possible. (fix all un-want but LDD allow slightly stud offset or slightly bricks collisions, gaps)
It fix all errors and collisions in my update version of 10196 Grand Carousel.(
Make 10221 Super Star Destroyer much easier to assembly.
I would like to help anyone if you don't have this kind of software.
Of course if you good in mathematics, you can calculate by a scientific calculator or even just by pen and paper!
Thanks to 'Bojan Pavsic's information:
"LDD works with more then 2 decimals... It only displays/rounds to 2 of them."
