I created two objects as follows:

pseudoatom A1, pos=[10.0, 10.0, 100.0]
pseudoatom A2, pos=[10.0, 10.0, -200.0]

I want to create a bond between these two atoms. Could you please help me? I need to display a 2 fold axis passing through these points.

I tried to use make and fuse command. Might be I am doing some thing wrong. Please tell me the exact command, I should use.
My regards...
