Whenever I use a forming tool in a sheet metal assembly, the forming tool contains a ? in the feature tree.
When I check the references, every thing is OK and I don't have any broken or out of context references.
The images bellow show the feature tree and the references window.
Now my questions:
- What does this ? means?
- How can I prevent it to appear again?
an assembly and the forming tool is attached if you need to test it.
Thanks for any kind of advice.
