Hi Polar Bear,
This is probably because you are using the same building material for both objects I think. If you need them to show a line then and want to use the same material you can duplicate the material and name it differently say "Wood-1" and the other one "Wood-2". Then set the beams to have the other material name.
Cheers,
Gerald
