Hi, I am having trouble importing my URDF with the appropriate physics and joint constraints. I have made a camera gimbal model and exported the model as a URDF using a solidworks to URDF. Then, when importing the URDF to Isaacsim, I am able to see it, but when I simulate it, the physics do not work at all. The gimbal always shifts to the same angle and gets stuck there and does not abide by the physics. Note: the baselink (top mounting bracket) is fixed for this model.
The gimbal before looks normal (I would put a picture but cannot since I am a new user).
No matter the starting orientation before the simulation starts, here is the gimbal after:
