Unable to view double bonds from PDB file Firstly, let me say that I am an organic chemistry graduate student and have very minimal experience with Blender itself. I am trying to use the atomic blender add on to make the molecules I have made in our computational software 3D printable. 

However, currently I am experiencing trouble viewing the double bonds of any pdb file I import. I am exporting the file from Spartan Student. It is of pentafluorobenzene. The pdb file reads as such:

The structure opens fine, no errors appear. The bond box is checked. Everything is bonded as it should be EXCEPT I cannot see any double bonds. All of the bonds are represented by one stick, regardless of whether they are actually double bonds or single bonds.

Can anyone propose a solution to fix this? Thank you in advance.
PDB doesnt support bond types  , check here https://discuss.avogadro.cc/t/pdb-file-format-and-double-bonds/2293
but you can edit the pdb file in a notepad like so :https://youtu.be/YNoow7qkwFA?t=364
