To create an Hexaedron in the Main Menu select Model -> Add hexa
There are 2 algorithms to create an Hexaedron.
Firstly you can define an Hexaedron through Quad 1, Quad 2, Quad 3, Quad 4, Quad 5, and Quad 6.
Arguments: 6 quadrangles
The dialogue box for the creation of an hexahedron from quads is:
Create an Hexahedron from quads
Secondly you can define an Hexaedron through Vertex 1, Vertex 2, Vertex 3, Vertex 4, Vertex 5, Vertex 6, Vertex 7, and Vertex 8, which ares the points through wich the Hexaedron passes.
Arguments: 8 vertices
The dialogue box for the creation of an hexahedron from vertices is:
Create an Hexahedron from vertices
TUI command: Hexahedron
