Hi All,

I'm using VMD 1.8.6. I'd like to draw a circle. The circle consists of
154 atoms. Its center is ( 0, 0, 0 ), and the radius is 6,500
Angstrom. The circle is in the YZ plane. The PDB file is in the

I use the command "mol new test.pdb type pdb start 0 end 0 step 1
autobonds off" to open the PDB file. The problem is the output is not
a circle, but a line!

Do you think the size of the radius has exceeded the limitation of
VMD? What's the biggest size in VMD? Or is there anything wrong in the
PDB file?

Thank you so much!
