Getting sub components of site about xbimessentials HOT 3 OPEN

When you say subcomponents, do you mean the geometrical parts (often terrain surface in case of IfcSite), or do you mean semantic breakdown (building(s), level(s), space(s))?

from xbimessentials.

Subcomponents in case of HOOPS is breakdown like buildings and other subcomponents of different Ifc elements.
In case of xbim how to achieve above?

You just need to iterate through the aggregation relation recursively.

private static void ExploreDecomposition(IIfcObjectDefinition entity, string indent)
{
    Console.WriteLine(indent + entity.Name);
    var children = entity.IsDecomposedBy.SelectMany(r => r.RelatedObjects);

    indent += "    ";
    foreach (var child in children)
    {
        ExploreDecomposition(child, indent);
    }
}

var site = model.Instances.FirstOrDefault<IIfcSite>();
ExploreDecomposition(site);

Note: Code is subject to optimisation and refactoring before used in production.
