\page build_by_blocks_page Building by blocks
-<h2>Introduction</h2>
-
-Below are some general notions about blocks:
-
A block is a an elementary geometric solid that has specific
-geometric constraints oriented for meshing. In the hexahedral case,
-blocks have 6 faces and each face has 4 edges.
-
-Tetrahedral Block - is a block with constraints for tetrahedral
-meshing.
-
-Hexahedral Block - is a block with constraints for hexahedral meshing.
-
-Block Compound - is a compound composed of blocks only.
-
-Some functionalities that allow building blocks easily are available from the main menu via <em>New
-Entity / Blocks</em>.
+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.
