Bond Config

Define here the visual style applied by default to new bonds.


This menu controls which style is applied by default when creating a new bond: a cylinder in solid mode or a line in wired mode.

Cylinders provide a better visual quality, when coupled with lights, but demand more screen space and processing time. Lines become poorly visible when using lights, unless the ambient component is significant, as diffuse and specular lights are not reflected.


This parameter controls the size applied by default when creating bonds in Solid mode. Combining bond Size with atom Variancy and Size, it is possible to obtain a wide range of styles to represent atomic structures.

The default is to represent atoms (Size = 0.8) slightly larger than bonds (Size = 0.5). An elegant style is to represent bonds with the same Size as atoms (0.5).

To guarantee that bond cylinders are closed by atom spheres, bond Size should not be larger than atom Size.


This button controls whether by default the bond is represented with its own, independent color, or inherits the colors of the parent atoms.

r, g, b

These entries set the color used by default, between black (0.0, 0.0, 0.0) and white (1.0, 1.0, 1.0), when bonds are rendered with their own independent color.
