The definition of the section to update.
Example

In This Topic
    UpdateSection Method (VoxelVolume)
    In This Topic
    Updates the section identified by the input SectionDefinition. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public void UpdateSection( 
       SectionDefinition sectionDef
    )
    Public Sub UpdateSection( _
       ByVal sectionDef As SectionDefinition _
    ) 

    Parameters

    sectionDef
    The definition of the section to update.
    Exceptions
    ExceptionDescription
    This method or property must be called within the lambda passed to QueuedTask.Run
    Invalid section definition specified
    Section not found in the collection of sections
    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);
    }
