Dof 1 for translation along x

Dof 2 for translation along y

Dof 3 for translation along z

Dof 4 for rotational along x

Dof 5 for rotational along y

Dof 6 for rotational along z


So if you uncheck field in hm that means you are allowing model to translate or rotate according to DOF which you switched off.

If all are checked or switch on(dof 1-6) then model is completely fixed.So in your case uncheck dof 4 for allowing rotation along x.
