Creates a dome shape (i.e. a hemisphere; half a sphere) with a specified radius of the defined node, optionally specifying the direction it should be pointing in (defaults to the positive y direction). Creates a dome shape (i.e. a hemisphere; half a sphere) with a specified radius of the defined node, optionally specifying the direction it should be pointing in (defaults to the positive y direction).
For example, `//dome+ 5 stone y` creates a dome shape pointing upwards, but `//dome+ 5 stone -y` creates a dome shape pointing downwards. For example, `//dome+ 5 stone y` creates a dome shape pointing upwards, but `//dome+ 5 stone -y` creates a dome shape pointing downwards.
Multiple pointing direction axes can be chained together to create multiple domes on top of each other. Multiple conflicting directions will cancel each other out. Multiple pointing direction axes can be chained together to create multiple domes on top of each other. Multiple conflicting directions will cancel each other out.
If `h` or `hollow` is specified at the end, then the resulting dome shape is made hollow.
