Generation

WorldEdit comes with a few commands help you make shapes without the use of a region selection. Instead, it takes the block that you are standing in as the center of these shapes.

To understand the command syntaxes, check the Commands page.

Spheres and Domes

;sphere [-hr] <pattern> <radius> [radiusY] [radiusZ] [-d <dome>]
;hsphere [-r] <pattern> <radius> [radiusY] [radiusZ] [-d <dome>]

This generates a sphere or spheroid of any dimensions. You can also define 2, or 3 numbers to define the radius in different axes. -h makes it hollow, and -r raises the sphere's bottom to the origin. By adding the -d flag along with a direction, you can turn the sphere into a dome. For example, ;sphere -d up stone 10 creates a top half dome of stone.

Cylinders

;cyl [-hr] <pattern> <radius> ([radiusY]) [height] [-d <direction>]
;hcyl [-r] <pattern> <radius> ([radiusY]) [height] [-d <direction>]

This generates a cylinder of any dimensions. You can also define 2 numbers to define the radius in different axes. Again, -h makes it hollow, and -r raises the its bottom to the origin. To change the direction the cylinder generates in, add the -d flag along with a direction. For example, ;cylinder -d north stone 4 10 creates a stone cylinder pointing north.

Pyramids

;pyramid [-h] <pattern> <size>
;hpyramid <pattern> <size>

This generates a pyramid. Unlike the previous two shapes, the center is at the base of the pyramid.

Toruses

;torus [-h] <pattern> <outerRadius> <innerRadius> [-d <direction>]

This generates a torus with varying inner radius and outer radius. Outer radius is how big the torus is, and the inner radius is how thick it is. -r and -d behave the same way as in Cylinders. Whether the torus generates from its bottom, and the direction it generates in.

Lofts

;loft start_curve
;loft add_point
;loft set <pattern>
;loft remove
;loft clear

Lofts are a group of segments that form a shape. These can be used to make things like flags and ramps. Because of how complex they are, there are four subcommands to manage their creation.

;loft start_curve creates a new starting point for a segment of your loft curve; using your current position. You grow the segment by using ;loft add_point. A loft needs at least 2 segments to be usable.

Once you have all your segments, use ;loft set <pattern> to fill it in with your pattern of choice. For example, ;loft set wool. If you want to remove points from your selection, use ;loft remove To remove the last point added. And if you want to remove everything, use ;loft clear.

Custom Shapes

Apart from these builtin shapes, there's also the ability to make your own with the ;gen command!

;gen [-h] <pattern> <expression>

Unlike the others, you need to first make a selection to define where the shape will be made. Then, you need to define an expression that will determine where blocks will be generated. If it returns true or a number besides 0, then a block is generated. You can use the three variables x, y and z to reference the location, which is normalized within the selection ([-1, -1, -1] - [1, 1, 1]). You also have a bunch of math functions at your disposal. Experiment!
