SectionDefinition Class
In This Topic
Represents the definition of a section. Refer to ArcGIS.Desktop.Mapping.VoxelLayer
Object Model
Syntax
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
{
//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
{
// Note: call within QueuedTask.Run()
{
if (voxelLayer.Visualization != VoxelVisualization.Surface)
voxelLayer.SetVisualization(VoxelVisualization.Surface);
voxelLayer.SetSectionContainerExpanded(true);
voxelLayer.SetSectionContainerVisibility(true);
//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 section = MapView.Active?.GetSelectedSections()?.FirstOrDefault();
if (section != null)
{
//Do something with the section
}
}
Get Voxel Layer for the Selected Section in TOC
{
voxelLayer = null;
var section = MapView.Active?.GetSelectedSections()?.FirstOrDefault();
if (section != null)
{
voxelLayer = section.Layer;
//TODO - use the layer
}
}
