First it was called DrilledCrossTile1D, but Jacques suggested to give it another name:

The name of the file should be in snake_case, please. Also, consider naming the tile DrilledCrossBeams or TwistedCrossBeams to avoid confusion...

so, Cross1D? @jzwar

[jzwar]

I don't want the dimensionality to be part of the tile's name. This is why I added the para_dim and dim properties to the tiles. If you feel like this is insufficient, we can change the directory structure to

tiles.
├── 1D
│   └── drilled_beam.py
├── 2D
│   └── cross_2d.py
│   └── ...
└── 3D
    └── ...
    └── ...

though I personally feel like this is unnecessary... We can add a module function show_available_tiles or something similar

@jzwar don't we already have Cross2D/Cross3D? However, I guess this is X. What about X?

[j042]

as X is not recommended class name, let's go with Chi
