GAMGI Interfaces: Direction Measure

# Direction Measure

- Length
- Angle

Measure Length properties involving directions.

### Quantity

The supported Length properties are listed below. Directions 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.

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.

Direction Node Length

The length per node along a crystallographic direction. The Direction parent must be a cell object.

Direction Node Density

The number of nodes per unit length along a crystallographic direction (the inverse of the previous quantity). The direction parent must be a cell object.

Direction Atom Distance

The distance from a direction to an atom.

### Value

After selecting a quantity, enter the name of the objects and press Ok. If all objects are recognized, GAMGI does the calculation and shows the result in the Value entry.

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.
