Display Horizons: Turn horizons off or control their display thickness. Choose from:

• Off
• Thin
• Medium
• Thick

Show horizon labels: Turn this item on to automatically display horizon labels in the left annotation area. If horizons are turned off, you will not see the labels.

Font: Define a font for the horizon labels.

Font Size (Points): Define the size of the font in standard font point size.

Show 2D horizon intersections: Turn this item on to automatically display horizon intersections between two 2D lines. The intersecting horizon will display as an X. If horizons are turned off, you will not see the intersections.

Show horizon/fault contacts: Turn this item on to automatically display horizon/fault contacts on the seismic section. The contacts will be highlighted with a circle around the contact in the horizon's color. If either horizons or faults are turned off contacts will not be visible.

Active Horizon Color: This control allows the user to specify the color of the active horizon. The active horizon is the horizon that is currently being edited.

3D Inline/Crossline Overlay In Traces: This property allows you to control overlay of a shadow horizon when displaying 3D inlines or crosslines. When 0 is specified no overlay horizon will be displayed. When a value of 1 or greater is specified, all horizons parallel to the current display for the given number of traces will be stacked and averaged into a shadow horizon that is displayed on the current line. For example, if you specified 5, the picks at each trace for the next 5, and previous 5 lines will be stacked together and displayed at the average time location as a shadow horizon.

Horizon Graph: Opens the Horizon Graph dialog. This dialog allows you to set up a graph of a horizon on the bottom of your seismic section.
