I'd like to know if it's possible to duplicate an object along a curve so that it follows the curve but only rotate on one axis (Z axis), and not on the X or Y axes. First picture is the result I want, second picture is the result I get with an Array + Curve Modifier. Dupliframes doesn't give any good result either. Thanks in advance!

EDIT : solution found with a Dupliframes, then a Constraint > Limit Rotation for my object... Thanks everyone
