#Custom Robot Import from Onshape

Hello, I recently started developing in Isaac Sim and have run into an issue. I’m importing a custom mobile robot from an Onshape assembly using the “Import from Onshape” feature, but I’m having trouble getting a revolute joint to use the correct parent and child prims. It seems like no matter how I configure the revolute joint in onshape, it does not affect the behavior of the robot in Issac Sim. As a temporary workaround, I removed the Articulation Root from the Assembly prim and reassigned it to the part I wanted to remain stationary. While this resolved the joint issue, it caused other parts of the robot to become detached and moved to (0,0).

I’d appreciate any guidance on how to properly configure the joint hierarchy or articulation setup so that everything behaves correctly.
