public void UpdateSection( 
   SectionDefinition sectionDef
)

Public Sub UpdateSection( _
   ByVal sectionDef As SectionDefinition _
)

Parameters

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run
System.ArgumentException	Invalid section definition specified
System.ArgumentException	Section not found in the collection of sections
System.ArgumentNullException	Section is null

Example

Update Section Orientation and Tilt

//var voxelLayer = ... ;
//Must be on the QueuedTask.Run()

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

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

//At 2.x - foreach (var section in voxelLayer.GetSections())
foreach (var section in volume.GetSections())
{
    //set each normal to 45.0 orientation and tilt
    section.Normal = voxelLayer.GetNormal(45.0, 45.0);
    //apply the change
    //At 2.x - voxelLayer.UpdateSection(section);
    volume.UpdateSection(section);
}

Update Section Visibility

//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().Where(s => !s.IsVisible);

//Use the SelectedVariableProfile to get the sections
//via its associated volume
var volume = voxelLayer.SelectedVariableProfile.Volume;
var sections = volume.GetSections().Where(s => !s.IsVisible);

//Make them all visible
foreach (var section in sections)
{
    section.IsVisible = true;
    //apply the change
    //At 2.x - voxelLayer.UpdateSection(section);
    volume.UpdateSection(section);
}
