Is rigid body axis locking actually implemented?

I just tried to lock some rotational/translational axes in the Rigit Body API, but it does not seem to have any effect in the simulation.

Any suggestions appreciated.

This is what I see, can you provide a .usd file with a simple repro scene if the issue persists?

Hi Hammand_M:
I have the same issue, but I need to control it by program, but I can’t find how to make it. Can you give me a demonstration to control the rigid body’s locked Pos Axis and locked Rot Axis?
Best regard with you!
