Faces
Faces can be built:
- 
               with the aid of automatic construction algorithm (automatic identification and creation) 
- by propagation from existing faces with the aid of a transformation
- by extrusion from existing lines with the aid of a transformation
Faces built by Flux PEEC
The faces built by Flux PEEC are included in planar surfaces. The types of faces are presented in the table below:
