I am a lead CAD designer for my robotics team, FRC #4239. We use Inventor 2017 for all our of our 3D design needs, and it suits us fairly well. Abruptly, all of our assemblies in a certain folder (the one we use for this year) are breaking, bringing up the all too familiar Resolve Link screen, however we cannot select the part to resolve, even though it clearly exists, the program simply resets itself asking for the same part over and over again.
After skipping all, nothing of the assembly remains. This error occurred after saving one of the assemblies after making all the parts Aluminum under the materials tab. At 9:46 this morning, all of the dependents under that file were saved, but the assembly itself is royally screwed. Earlier than that, it was completely fine, until we converted it to aluminum. All that remains is unsolved links, and strange boxes around the part icons on the left. Any assistance would be greatly appreciated. Much more info available upon request.
