- Measurement mode can be set in two ways:
- By setting the Picking Mode in the tool bar (near the top of the main Mercury window) to the required parameter type, viz. Measure Distance, Measure Angle or Measure Torsion.
- By right-clicking in the display area (but not on an atom, bond or object), selecting Measure from the pull-down menu, and then choosing Measure Distances, Measure Angles or Measure Torsions.
- Geometrical measurements (intramolecular or intermolecular) can now be displayed by clicking on e.g., two atoms for a distance, three atoms for an angle or four atoms for a torsion angle.
- Centroids can be used in distance, angle and torsion angle measurements.
- Planes can be used in distance measurements with other planes, atoms and centroids. Angles between planes can also be measured.
