I have a specific question about external references.
I got an assembly from a colleague.
In that assembly there are 3 different components (parts).
One of them (4 incher) has red errors because of external references and I don't know how to fix it. When I see the list of external references it says that it's in the part that that's in the assembly, but I don't know how to fix it.
So here's a screenshot of the assembly (1.png). 4 incher is the part that has an error (2.png). on pic 3 you can see 2 extrude cuts that are red. On pic 5 you can see the list of external references and it says that it should be in the part that's named Angle gusset. But I don't understand what's wrong and why is it red ?
