The rotation axis defines a rotation center and limits the rotation to one • degree of freedom. It should be used in

Most of the rotation of parts are only around one axis.

I think this is not true, you can rotate any part however you like, since
there are a lot of parts which allow to connect other parts in various angles.
E.g. this thing with two plates (don't know how it's called in english) which
can be opened up to 270 degrees - the plates are connected with an axis.
Theire are also parts which connect two parts in an angle of 90 degree ...

I agree. See all the technic parts that are connected with pins.

I think i have not explained myself very clearly. I have tried to be more clearly with some pictures.
Heve a look on the page http://marc.klein.free.fr/rotation.html

I also describe on that page another idea for automatic placement of parts using rotation center directive.
I hope it is clear enough.
