# Atom Measure

- Length
- Angle

Measure properties involving the Length between atoms and other objects.

### Property

The supported Length properties, the same as for Atom->Modify, are listed below. Atoms and other objects may belong to different parents and may be 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.

2-Atom Distance

The distance between two Atoms.

Atom 2-Atom Distance

The distance between Atom1 and the direction defined by Atom2-Atom3.

Atom 3-Atom Distance

The distance between Atom1 and the plane defined by Atom2-Atom3-Atom4.

Atom Direction Distance

The distance from an Atom to a Direction.

Atom Plane Distance

The distance from an Atom to a Plane.

### Value

After selecting a property, 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 property or page is chosen, previous data is automatically removed.
