Blank Grids Using Geometry
(Select multiple 2D or 3D grid files and a single geometry item)
Use this operation to blank nodes in multiple grid files based on points, line, or polygon (geometry).
Use Geometry As:
Although the geometry item may be either points, line, or polygon. It can always be used as points if it is really a polygon and so on. However, the default selection will correspond to the selection made in the main form of the Toolbox.
Points:
The blanking will affect nodes within or outside the specified radius.
Line:
The blanking will affect nodes within or outside the specified radius (buffer).
Polygon:The blanking will affect nodes either inside or outside the polygon.
Blank:
Inside:
Blank within radius or polygon.
Outside:
Blank outside radius or polygon.
Settings:
Radius:
Radius used for points and lines. The radius is always in the XY-plane. Blanking 3D grids using points will produce a cylindrical blanked volume.
