The quality evaluation of building surface of the prizmatoid

The article presents some analogies between the side surface of the prizmatoid and the regular ruled surface. The notions to the side faces of the prizmatoid are introduced: the face of parabolic type and the face of hyperbolic type, straight edge and cross edge, homogeneous and heterogeneous face. The consistency of the surface is the numerical characteristic of the surface as a whole. It is introduced and offered as a comparative assessment of the quality of construction of a surface of the prizmatoid.
