Shape Types and Parameters

An index of all 22 parametric shape types, linking to the detailed page for each one.

There are 22 parametric shape types. Parameters, value ranges, how to draw them and practical tips live on each shape's own page.

Shape	kind	Summary
Layout	`layout`	Mesh-less AABB box; the anchoring reference for children

Shape	kind	Summary
3D Text	—	3D text extruded from a string (Inspector-only)

The size parameters shared across shapes, with their script keys. Per-shape meanings and ranges are on each shape's page.

Script key	Canonical name	Usual meaning
`w`	`width`	Size along local X
`d`	`depth`	Size along local Z
`h`	`height`	Size along local Y
`r`	`radius`	Radius
`r1` · `r2`	`radius1` · `radius2`	Outer and inner (or section) radius
`th`	`thickness`	Thickness
`sh` · `sw`	`stepheight` · `stepwidth`	Step height and stair width
`ang`	`angle`	Angle
`seg` · `sides` · `rings`	`segments` · `sides` · `rings`	Segment counts

Changing the type in the Inspector's Shape Type grid keeps the GameObject and its transform and rebuilds only the form.

Parameter values are preserved. Parameters the new type does not use simply sit unused, and they come back if you switch to that type again.
Values outside the new type's allowed range are clamped automatically.
To return to defaults, use Reset in the component's right-click menu — it reinitializes everything to the current type's defaults.
