class Area3dBuilder from BOP inherits AreaBuilder from BOP

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