physics of rotation, question.

[telobarsik]

how to block the rotation of an atom along any of the axes?
for example, I need the atom to rotate only along the x-axis.
I need to make a propeller, I turn off the rotation lock, and push it with my hand and it starts to rotate in all directions, both along the x-axis and along the y-axis, etc. I want it to rotate only on the x-axis.

There are "lock" checkboxes in the Move tab of most atoms

it doesn't work when physics is enabled.

Yeah... the locks works only on the controllers. Not on the actual rigid body. I think what you asking is not possibile atm. If your atom is some sort of "disc" you can try to add invisible cubes on the sides (for collision) but... i think that such scenario is a pain for physics computing. So... be carefull.
