Time/Depth Velocity Modeling: Layer Details Polygon Options
The Polygon Options tab in the Layer Details dialog box is used to select the polygons that you want applied when performing the calculation for the layer currently selected in the Layers dialog box.
Polygon Control
Place a check mark next to Constraining polygons, Clearing polygons, or Fault Polygons, and click 
to open the Select Polygons dialog box.
Constraining Polygons:Use
a polygon to select the seed points for the grid. If using an inclusion
polygon, only the seed points within the polygon will be used to create
the grid. If using an exclusion polygon only the seed
points not within the polygon will be used. This polygon will not
affect the size or shape of the output grid.
Optional
Clearing Polygons:Use
a polygon to define the bound of the output grid. This is applied after
the gridding is complete. If using an inclusion polygon,
everything outside of the polygon will be removed from the grid. If
using an exclusion polygon, everything within the polygon will be
removed from the grid.
Optional Fault Polygons:Use a polygon to define fault regions. Seed data points are ignored if they are on the other side of a fault boundary.
