Invalid File Path - 2018 In-CAD

[karthur1]

I opened a previous assembly that I had been working on.  Now when I run the solver, I get the error message " Nastran file cannot be cread due to invalid file path, Save the file once again and continue".

I save the .iam and closed Inventor.  Reopened the file and re-ran the solver.  Still get the same error.

Not sure what file has the invalid file path, but my iam is checked-out.  When I look at the .NAS file in windows Explorer, here is the file path to it.  No special characters in the path.

I figured it out.  Since the files under the In-CAD folder in vault was not checked out, this is hwat was causing the error.  I went into Vault and checked-out the files.  Now the solver runs.

Sorry.
