Hi Darrell!
Sorry, there isn't any PDB biological unit fetch … one has to download them from the RCSB website, then open "manually" in Chimera.  We have  discussed changing from PQS to PISA in the fetch interface (trac ticket #10237), but it hasn't been done.
Best regards,

The PDB itself provides the biological unit(s) for download in their weird ".pdb1", ".pdb2", etc. format for every entry in the database (even if it is redundant). Is there a way to grab those files from the PDB itself using the Chimera interface? The repository is in:
