From a list of quadrangles, a set of hexahedra is created.

### Simple Extrude¶

The dialogue box to make a simple extrude of quadrangles is:

Arguments:

• Nb layers : the number of layers of hexahedra resulting from the extrusion.

The direction of the extrusion is the vertical axis (Z axis).

TUI command: Simple Extrude

### Uniform Extrude¶

The dialogue box to make a uniform extrude of quadrangles is:

Arguments:

• dircection: the direction of the extrusion.
• length : the length of hexahedra resulting from the extrusion.
• Nb layers : the number of layers of hexahedra resulting from the extrusion.

TUI command: Uniform Extrude

### Custom Extrude¶

The dialogue box to make a custom extrude of quadrangles is:

Arguments:

• direction : the direction of the extrusion.
• height : a list of heights (in ascendant order because the size is computed from the origin) to specify the size of each layer of extrusion.

TUI command: Custom Extrude

Arguments:

• Quad(s) : the set of quadrangles to be joined and from which hexahedra will be created.
• From point a: a vertex belonging to the first quadrangle of the set of quadrangles.
• From point b: a vertex, consecutive to previous Point a, belonging to the first quadrangle.
• To point a : the target vertex (in the target quadrangle) for From point a.
• To point b : the target vertex (in the target quadrangle) for From point b.
• Nb layers : number of layers of hexahedra issued from the operation.

TUI command: Uniform Join

Arguments:

• Quad(s) : the set of quadrangles to be joined and from which hexahedra will be created.
• From point a: a vertex belonging to the first quadrangle of the set of quadrangles.
• From point b: a vertex, consecutive to previous Point a, belonging to the first quadrangle.
• To point a : the target vertex (in the target quadrangle) for From point a.
• To point b : the target vertex (in the target quadrangle) for From point b.
• height : a list of heights to specify the size of each layer of hexahedra issued from the operation.

TUI command: Custom Join
