Hi Kai,
Did you write the file as PDB or mmCIF when you saved it from ChimeraX?  When I use Build Structure to join a NAG to an ASN, the resulting PDB file has the proper LINK/CONECT records.

Dear colleagues,

I am trying to build a N-glycan into my model using 'bond' command with ChimeraX, by connecting the ND2 atom from an ASN residue to the C1 atom of the N-glycan (NAG). However, the manually built bond didn't show up when I opened the coordinates in Coot. Is there a way to overcome this issue? The bond length is 1.4 Å. Thanks in advance! 

Cheers,
Kai
