Define here the length limits used to create new bonds.

### Element, Element

When the Element entries are empty (the default), GAMGI attempts to create bonds for all pairs of atoms. When the Element entries are occupied with valid element names, only bonds between atoms of these elements are considered. When creating Delaunay bonds, only topological bonds between atoms of the selected elements will be created.

When both elements are recognized, minimum and maximum bond length limits for this element pair - calculated according to the rules described below - are automatically writen in the Minimum, Maximum entries, otherwise these entries are left empty.

When pressing Ok, the Element entries must be both empty or valid, otherwise an error dialog is shown.

### Minimum, Maximum

When the Minimum, Maximum entries are empty (the default), GAMGI attempts to use its own data to set a valid range of bond lengths, for each element pair.

For each atom pair, GAMGI checks whether specific minimum and maximum bond length limits have been configured. If the atoms distance is in the configured interval, a new bond is created. To configure bond length limits for specific element pairs, select Bond->Config.

If no bond length interval has been configured for this element pair, GAMGI attempts to calculate automatic minimum and maximum limits, summing the two atom radius and multiplying by lower and upper factors (currently 0.80 and 1.10 by default). If the atoms distance is in the calculated interval, a new bond is created. To configure these lower and upper factors, valid for all element pairs, select Bond->Config.

If no radius is defined for at least one of the elements, then no bond is created. To configure the atom radius, for specific elements, select Atom->Config.

When the Minimum, Maximum entries are occupied with valid length values, only bonds between these limits will be considered, for all element pairs. When creating Delaunay bonds, only topological bonds with lengths in the selected range will be created.

When pressing Ok, the Minimum, Maximum entries must be both empty or valid, otherwise an error is shown. The Minimum cannot excede the Maximum length, otherwise an error is shown.
