class Area3dBuilder from TopOpeBRepBuild 
    inherits AreaBuilder from TopOpeBRepBuild

---Purpose: 
-- The Area3dBuilder algorithm is used to construct Solids from a LoopSet,
-- where the Loop is the composite topological object of the boundary,
-- here wire or block of edges.
-- The LoopSet gives an iteration on Loops.
-- For each Loop  it indicates if it is on the boundary (wire) or if it
-- results from  an interference (block of edges).
-- The result of the Area3dBuilder is an iteration on areas.
-- An area is described by a set of Loops.
