Square prism

Notes:

  • Faces and corners are referred to using compass directions, with north oriented in the direction of positive y-axis.
Symmetry option Equivalent surfaces Equivalent corners Symmetry axis
0, NO, NONE - - -
1, ALL W-S-E-N NW-NE-SE-SW -
2, NS, SN N-S NW-SW, NE-SE from side E to side W
3, NESW, SWNE N-E, S-W SE-NW from corner NE to corner SW
4, EW, WE E-W SW-SE, NW-NE from side N to side S
5, NWSE, SWNE N-W, S-E NE-SW from corner NW to SE

Hexagonal prisms

Notes:

  • The face and corner directions are listed in Assembly discontinuity factors.
  • The corner symmetries have been wrong prior to version 2.1.32. The list below corresponds to the correct values used since version 2.1.32.
  • Symmetry options 8 and 9 were added in version 2.1.32.
Symmetry option Equivalent surfaces Equivalent corners Symmetry axis Note
0, NO, NONE - - -
1, ALL, 30 1-2-3-4-5-6 1-2-3-4-5-6 - useful for 30 degree periodic symmetric hexagonal lattices
2 2-6, 3-5 1-4, 2-3, 5-6 from side 1 to side 4
3 1-2, 3-6, 4-5 1-3, 4-6 from corner 2 to corner 5
4 1-3, 4-6 1-2, 3-6, 4-5 from side 2 to side 5
5 1-4, 2-3, 5-6 2-6, 3-5 from corner 1 to corner 4
6 2-4, 1-5 1-6, 2-5, 3-4 from side 3 to side 6
7 1-6, 2-5, 3-4 1-5, 2-4 from corner 3 to corner 6
8, 60 1-2-3-4-5-6 1-3-5, 2-4-6 - useful for 60 degree periodic symmetric hexagonal lattices
9, 120 1-3-5, 2-4-6 1-3-5, 2-4-6 - useful for 120 degree periodic symmetric hexagonal lattices
