====== 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.
