Extrude and join quadrangles¶
Extrude Quadrangles¶
To extrude from quadrangles in the Main Menu select Model -> Operation -> Extrude Quadrangles.
From a list of quadrangles, a set of hexahedra is created.
Simple Extrude¶
The dialogue box to make a simple extrude of quadrangles is:

Simple Extrude From Quadrangles
Arguments:
- Quad(s) : the list of quadrangles to be extruded.
- 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:

Uniform Extrude From Quadrangles
Arguments:
- Quad(s) : the list of quadrangles to be extruded.
- 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:

Custom Extrude From Quadrangles
Arguments:
- Quad(s) : the list of quadrangles to be extruded.
- 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
Join Quadrangles¶
To join quadrangles in the Main Menu select Model -> Operation -> Join Quadrangles.
Uniform Join Quadrangles¶

Uniform Join Quadrangles Dialog Box
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.
- Quadrangle : a quadrangle from the set of targeted quadrangles.
- 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
Custom Join Quadrangles¶

Custom Join Quadrangles Dialog Box
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.
- Quadrangle : a quadrangle from the set of targeted quadrangles.
- 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
