Measure <b>Length</b> properties involving planes.
<h3>Quantity</h3>
The supported <b>Length</b> properties are listed below. Planes
and other objects selected may belong to different structural systems
(cells, molecules, etc.), bonded or not. Only objects in the current
layer can be chosen.
<p/>
An easy technique to select the objects is to click the mouse
sucessively over their visual representations, in the sequence
shown in the dialog. After the last needed object is selected,
GAMGI automatically starts the calculation.
<p/><b>Plane Separation</b><p/>
The distance between adjacent crystallographic planes.
The plane parent must be a cell object.
<p/>
The reported length is always the distance calculated from the
equation <b>d(hkl) = K/G(hkl)</b>, where <b>G</b> is the reciprocal
lattice vector for planes <b>(hkl)</b> and <b>K</b> is the reciprocal
lattice constant (the vector <b>G</b> is also proportional to <b>K</b>,
so the result is independent of the reciprocal lattice constant).
<p/><b>Plane Atom Distance</b><p/>
The distance from a plane to an atom.
<h3>Value</h3>
After selecting a quantity, enter the name of the objects and
press <b>Ok</b>. If all objects are recognized, GAMGI does the
calculation and shows the result in the <b>Value</b> entry.
<p/>
When a calculation ends, GAMGI keeps the objects identification.
To start a new calculation, just click the mouse over a new object:
GAMGI automatically cleans the previous data and inserts the new
object identification. When a new quantity or page is chosen,
previous data is automatically removed.
