Any node, segment or 2D element can be -extruded. Each type of elements has a corresponding type of extruded elements: +dimension than the input ones. Boundary elements around generated +mesh of plus one dimension are additionally created. All created +elements can be automatically grouped.

Any node, segment or 2D element can be extruded. Each type of +elements is extruded into a corresponding type of result elements:
Extruded element | Result element |
Node | Segment |
Hexagonal polygon | Hexagonal prism |
