Syntax
public class SectionDefinition 
Remarks
A section is a snapshot of data in the voxel that creates a plane. The plane is defined by a position and a direction defined by a normal unit vector. Refer to Voxel layer sections
Example
Get/Set Selected Voxel Assets from the TOC
var surfaces = MapView.Active.GetSelectedIsosurfaces();
//set selected w/ MapView.Active.SelectVoxelIsosurface(isoSurface)
var slices = MapView.Active.GetSelectedSlices();
//set selected w/ MapView.Active.SelectVoxelSlice(slice)
var sections = MapView.Active.GetSelectedSections();
//set selected w/ MapView.Active.SelectVoxelSection(section)
var locked_sections = MapView.Active.GetSelectedLockedSections();
//set selected w/ MapView.Active.SelectVoxelLockedSection(locked_section)
Get a Section
//var voxelLayer = ... ;
//Must be on the QueuedTask.Run()

//At 2.x -
//var section = voxelLayer.GetSections().FirstOrDefault();
//var section2 = voxelLayer.GetSections().First(sec => sec.Id == my_section_id);

//Use the SelectedVariableProfile to get the sections currently in the TOC
//via its associated volume
var volume = voxelLayer.SelectedVariableProfile.Volume;

var section = volume.GetSections().FirstOrDefault();
var section2 = volume.GetSections().First(sec => sec.ID == my_section_id);
Get the Current Collection of Sections
//var voxelLayer = ... ;
//Must be on the QueuedTask.Run()

if (voxelLayer.Visualization != VoxelVisualization.Surface)
    voxelLayer.SetVisualization(VoxelVisualization.Surface);
voxelLayer.SetSectionContainerExpanded(true);
voxelLayer.SetSectionContainerVisibility(true);

//At 2.x - var sections = voxelLayer.GetSections();

//Use the SelectedVariableProfile to get the sections currently in the TOC
//via its associated volume
var volume = voxelLayer.SelectedVariableProfile.Volume;
var sections = volume.GetSections();

Get the Selected Section in TOC
//var voxelLayer = ... ;
//Must be on the QueuedTask.Run()

var section = MapView.Active?.GetSelectedSections()?.FirstOrDefault();
if (section != null)
{

}
Get Voxel Layer for the Selected Section in TOC
//var voxelLayer = ... ;
//Must be on the QueuedTask.Run()

VoxelLayer voxelLayer = null;
var section = MapView.Active?.GetSelectedSections()?.FirstOrDefault();
if (section != null)
{
    voxelLayer = section.Layer;
    //TODO - use the layer
}
