### Remarks

A negative value will automatically be converted into a positive value. If only a single radius axis is enabled, the value will automatically be converted to `0`. This value can never exceed half the [CapsuleBoundsHandle.height](/engine/6000.6/script-reference/unityeditor/imgui/controls/capsuleboundshandle/height.md).
