KeyError: Component2_1

[VibhanshuV]

I am trying to export my bipedal robot to URDF but I am getting the following error. I have attached the Joint2Graphviz result which seems fine to me and my fusion assembly. Please help.

It does get into issues when you have copies of components with same names like "Component 2:1" and "Component 2:2" so when you create copies of components, paste them as new. I usually unlink the components too and rename them properly. I know it's difficult to make changes then but it makes the exporting process smoother.

I also faced this problem.

• links name
  
• fusion2urdf error
  

Once exported as a step file
Once I exported the step file as a step file and uploaded it to fusion360, the index value was unified to 1 and the fusion2urdf error was gone.

• links name after export and import stp
