The <b>Divided disk</b> object is a disk divided into \b blocks. It means that it's a shape <b>prepared for hexaedral meshing</b>.
The <b>Divided disk</b> object is a disk divided into \b blocks. It means that it's a shape <b>prepared for hexaedral meshing</b>. Two division patterns are available :
<ul>
<li> A square pattern which is frequently used </li>
<li> An hexagonal pattern which ensures a better mesh quality and especially less acute or obtuse angles </li>
</ul>
\n Moreover this shape can be used as a basis in an \ref create_extrusion_alongpath_page "Extrusion along a path" operation in order to obtain any <b>tube shape</b> prepared for hexaedral meshing
(see example below).
(see example below). (Another alternative is to create a 2D mesh on the divided disk and create a 3D mesh by extrusion in the SMESH module.)

\n For both operations :
Specify the parameters of the DividedDisk object creation in the opened dialog
box and press "Apply" or "Apply & Close" button.
Result of each operation will be a GEOM_Object.
The result of each operation will be a GEOM_Object.
\n First way : by radius and orientation (plane "OXY", "OYZ" or "OZX"). The resulting disk is located at the origin of coordinates
<b>TUI Command:</b> <em>geompy.MakeDividedDisk(Radius, Orientation)</em>
<b>TUI Command:</b> <em>geompy.MakeDividedDisk(Radius, Orientation, Pattern)</em>
<b>Arguments:</b>
- \b Radius - Radius of the disk
- \b Orientation - Plane on wich the disk will be built
- \b Pattern - Division pattern

\n Second way : by giving its center, normal and radius.
<b>TUI Command:</b> <em>geompy.MakeDividedDiskPntVecR(Center, Vector,
Radius)</em>
Radius, Pattern)</em>
<b>Arguments:</b>
- \b Center - Center of the disk
- \b Vector - Normal to the plane of the disk
- \b Radius - Radius of the disk
- \b Pattern - Division pattern
