> `readonly` **center**: [`Vec2`](https://jonbogaty.com/lifecycle-kit/api/forms/interfaces/vec2/index.md)

Defined in: [forms/rules/radiate.ts:15](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/forms/rules/radiate.ts#L15)

### count {#count}


> `readonly` **count**: `number`

Defined in: [forms/rules/radiate.ts:17](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/forms/rules/radiate.ts#L17)

How many copies.

### part {#part}


> `readonly` **part**: `string`

Defined in: [forms/rules/radiate.ts:27](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/forms/rules/radiate.ts#L27)

### spreadTurns {#spreadturns}


> `readonly` **spreadTurns**: `number`

Defined in: [forms/rules/radiate.ts:24](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/forms/rules/radiate.ts#L24)

Fraction of a full turn the copies spread across, 0..1. 1.0 is a full
ring (a sea anemone's arms, spokes of a wheel); a starfish with 5 arms
spread across the whole turn uses 1.0, while a fan of gills spread
across only the animal's front uses something smaller.

***


### startTurn? {#startturn}


> `readonly` `optional` **startTurn?**: `number`

Defined in: [forms/rules/radiate.ts:26](https://github.com/jbcom/lifecycle-kit/blob/074e4e7b8038d3e2de9eb44c4b5b5aee0ef02b48/src/forms/rules/radiate.ts#L26)

Turn at which the first copy sits. 0 is "along +x".
