Detailed Description

I created my own URDF file using SolidWorks. After launching Isaac Sim, I clicked on “File → Import” and selected my own URDF file, but then Isaac Sim froze. Seems like it can’t deal with STL file.

Steps to Reproduce

  1. start isaacsim: ./isaacsim/isaac-sim.sh
  2. click:file->import->my urdf file
  3. isaacsim was froze

could you confirm if you encounter the same freezing behavior when following Tutorial: Import URDF — Isaac Sim Documentation using the provided panda_arm_hand.urdf file?
