### worldedit.stack(pos1, pos2, axis, count)
duplicates the region defined by positions `pos1` and `pos2` along the `axis` axis ("x" or "y" or "z") `count` times.
Duplicates the region defined by positions `pos1` and `pos2` along the `axis` axis ("x" or "y" or "z") `count` times.
Returns the number of nodes stacked.
### worldedit.transpose(pos1, pos2, axis1, axis2)
Transposes a region defined by the positions `pos1` and `pos2` between the `axis1` and `axis2` axes ("x" or "y" or "z").
Returns the number of nodes transposed.
### worldedit.flip(pos1, pos2, axis)
Flips a region defined by the positions `pos1` and `pos2` along the `axis` axis ("x" or "y" or "z").
Returns the number of nodes flipped.
### worldedit.rotate(pos1, pos2, angle)
Rotates a region defined by the positions `pos1` and `pos2` by `angle` degrees clockwise around the y axis (supporting 90 degree increments only).
Returns the number of nodes rotated.
### worldedit.dig(pos1, pos2)
Digs a region defined by positions `pos1` and `pos2`.
