class HBuilder from TopOpeBRepBuild inherits TShared from MMgt
---Purpose: The HBuilder algorithm constructs topological
-- objects from an existing topology and new
-- geometries attached to the topology. It is used to
-- construct the result of a topological operation;
-- the existing topologies are the parts involved in
-- the topological operation and the new geometries
-- are the intersection lines and points.
