In Revit if querying wall thickness data, only need to access WallType. When modifying corresponding thickness need to enter structure layer: CompoundStructure similar to new thickness panel in our usage. It provides methods to create and modify compound layers

WallType type = WallTypes.ElementAt(0) as WallType;
WallType newType = type.Duplicate(name) as WallType;
//Wall Thickness
CompoundStructure cs = type.GetCompoundStructure();
CompoundStructure wallComPound = newType.GetCompoundStructure();
foreach (CompoundStructureLayer layer in wallComPound.GetLayers())
{
layer.Width = value / 304.8;
wallComPound.SetLayerWidth(layer.LayerId, layer.Width);
break;
}
newType.SetCompoundStructure(wallComPound)；

After modifying thickness need to pass value back to compound structure to let compound structure parameter of WallType change.
