Dialog Box: Composition Planes [ Twins Dialog]
This lists all the composition planes. Note that each composition plane is added to every twin individual - i.e. the composition planes are added before the main crystal is reproduced.
Compositions planes always pass through the center of the crystal - the central distance is zero.
Clicking on Add or Revise , or double-clicking on an individual entry takes you to the Composition Plane dialog (Standard or Cartesian) for entry or revision of data for individual composition planes
