Dialog Box: Line Patterns and Pens for Sections and Growth Zones [ Sections and Growth Zones Dialog ]

These are colors which only appear when the Display mode (Modes menu) is set to Section/Zoning. See the Sections and Growth Zones dialog for further definitions of terms.

One-face edges are the intersections of single crystal faces with the section plane. The same color is used for front section edges (visible edges) when the section edges are added to a normal view of the crystal with the Add button in the Sections and Growth Zones dialog.

Two-face edges are the intersections of crystal edges with the section plane. That is, the crystal edge lies in and is parallel to the section plane.

Sector boundaries. These lines are draw between section corners involving the same faces. They may be undefined when the morphology of a section changes.

Back edges are the back section edges (invisible edges) when the section edges are added to a normal view of the crystal with the Add button in the Sections and Growth Zones dialog.

Marker zones are lines which may be added (or actually substituted for the section edges) at specified intervals to growth zoning, especially when wide lines are being used to fill in sectors.
