Syntax: set solvent <boolean>
The RasMol set solvent command is used to control the behaviour of the RasMol dots command. Depending upon the value of the solvent parameter, the dots command either generates a Van der Waal's or a solvent acessible surface around the currently selected set of atoms. Changing this parameter automatically resets the value of the RasMol radius parameter. The command set solvent false, the default value, indicates that a Van der Waal's surface should be generated and resets the value of radius to zero. The command set solvent true indicates that a `Connolly' or `Richards' solvent accessible surface should be drawn and sets the radius parameter, the solvent radius, to 1.2 Angstroms (or 300 RasMol units).
