====== Pick Grid Nodes Tool ======

The Pick Grid Nodes Tool is used to select voxels surrounding a seed voxel selected by the user. The tool can be used on any 3D grid in the project if it has the same geometry as the 3D grid beeing edited. As an example the tool can be used to select voxels in a resistivity grid. The positions of the selected voxels are then used to set the lithology of voxels in another.

==== Settings ====

**Mode ** \\
__All:__ All voxels that meet the criteria are selected\\
__Region Grow: __ All voxels that meet the criteria and is connected to the seed voxel are selected. In other words the selected voxels are all members of the same volumen or body surrounding the seed voxel.

**Region Grow Mode ** \\
This mode defines how well neighbouring voxels should be connected to be considered\\
__Face:__ Voxels must have at least one common face. This is the default mode and is also the fastest.\\
__Face, Edge:__ Voxels must have at least one common face // or // edge.\\
__Face, Edge, Corner:__ Voxels must have at least one common face //or //edge //or //corner.

**Use Profile Buffer ** \\
Only voxels within the profile buffer is considered.

==== Value Selection ====

**Discrete Grids: ** \\
The selected value is simply shown. No further options are available.

**Floating Point Grids: ** \\
For floating point grids an interval surrounding the picked value must be defined\\
__Picked Value:__ The value in the voxel selected by the user. This is the seed voxel.\\
__Max Value Limit:__ A value larger than the picked value.\\
__Min Value Limit:__ A value smaller than the picked value.
