Hi all, 
I'm trying to add some 3d shapes to a visualization. I was wondering if it would be possible to draw either a cylinder or tube given starting and ending coordinates rather than atom names/numbers or centroid? For example, if I had this coordinate pair:

6.17 1.10 -15.33     20.82 -0.70 -8.39


What would be the best way to go about drawing a line of some sort between those two points? I have dozens of pairs of coordinates so something command line would be ideal. 

Cheers,

Rebecca
