7 Below are some general notions about blocks:
9 A block is a an elementary geometric solid that has specific
10 geometric constraints oriented for meshing. In the hexahedral case,
11 blocks have 6 faces and each face has 4 edges.
13 Tetrahedral Block - is a block with constraints for tetrahedral
16 Hexahedral Block - is a block with constraints for hexahedral meshing.
18 Block Compound - is a compound composed of blocks only.

30 <h2>Quadrangle face</h2>
32 \n <b>Description:</b> Builds a face using the below mentioned
33 arguments. This operation allows to build a face bypassing the
34 intermediate stage of building edges and wires (in the case of
35 building by 4 points) or wires (in the case of building by 4 or 2
38 \n The \b Result of the operation will be a \b GEOM_Object (face).
40 \n <b>TUI Command:</b>
42 <li><em>geompy.MakeQuad4Vertices(V1, V2, V3, V4),</em> where V1, V2,
43 V3, V4 are four vertices from which a face is constructed. Edges are
44 created automatically.</li>
45 <li><em>geompy.MakeQuad2Edges(E1, E2),</em> where E1, E2 are edges from
46 which the face is constructed, two other edges are created
48 <li><em>geompy.MakeQuad(E1, E2, E3, E4),</em> where E1, E2, E3, E4 are
49 four edges from which the face is constructed.</li>

73 <h2>Hexahedral solid</h2>
75 \n <b>Description:</b> Builds a hexahedral solid. either of the below
76 mentioned arguments. This operation allows to build a solid bypassing
77 the intermediate stage of building a shell and 4 faces (in the case of
78 building by 2 faces) or just a shell (in the case of building by 6
81 \n The \b Result of the operation will be a \b GEOM_Object (solid).
83 \n <b>TUI Command:</b>
85 <li><em>geompy.MakeHexa2Faces(F1, F2),</em> where F1 and F2 are faces
86 from which the hexahedron is constructed, other four faces are created
88 <li><em>geompy.MakeHexa(F1, F2, F3, F4, F5, F6),</em> where F1 — F6 are six faces from which the hexahedron is constructed.</li>
93 <li>Name + 2 Faces, or</li>
