<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.
|
|
|
|
These functionalities are available from the main menu via <em>New
|
|
Entity / Blocks</em>.

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

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