Linewidth changes the thickness of lines in the wire representation. The width is in pixels (default 1.0). Although any positive number can be given, there will be a maximum displayable width that depends on the graphics hardware being used.
If the atom-spec is blank, all molecule models will be affected; otherwise, the entire model(s) containing atom-spec will be affected. If an affected model is in a representation other than wire, the change in linewidth will not be evident until part or all of the model is shown as a wire. Linewidth can also be changed in the molecule model attributes panel.
For large structures, thick lines may be preferable to the stick representation, as lines are simpler to render.
