/*! \page build_by_blocks_page Building by blocks A block is a an elementary geometric solid that has specific geometric constraints oriented for meshing. - Tetrahedral Block - is a block with constraints for tetrahedral meshing. It has 4 faces and 3 edges on each face. - Hexahedral Block - is a block with constraints for hexahedral meshing. It has 6 faces and each 4 edges on each face. - Block Compound - is a compound composed of blocks only. The functionalities that allow building blocks are available from the main menu via <b>New Entity / Blocks</b> item. <ul> <li>\subpage create_quadrangle_face_page "Quadrangle face"</li> <li>\subpage create_hexa_solid_page "Hexahedral solid" </li> <li>\subpage create_divideddisk_page "Divided disk" </li> <li>\subpage create_dividedcylinder_page "Divided cylinder" </li> </ul> */
