I've got a user who, when using Navisworks, gets the "can't resolve external reference" error on numerous files.
This seems to be a standard error based on what other users here have stated. They would typically just select the "Ignore all" button and carry on. The parts would still load/show in Navisworks without issue.
But this one has a few files that simply do not show up in Navisworks, even though they are in the Inventor model.
One thing we have noticed is Navisworks only seems to "see" files that reside within the main directory of the project. It doesn't find any files that reside in our Vault libraries.
(all project work is located in subfolders under the "ENG" folder, all standard parts reside in the various Library folders):
Ideas?
