Replicates the 3D solid, applying a transformation function to each replica. Transformation function could alter rotation, scale, visibility, position, etc.
The `patternTransform` call itself takes a number for how many total instances of the shape should be. For example, if you use a circle with `patternTransform(4, transform)` then there will be 4 circles: the original, and 3 created by replicating the original and calling the transform function on each.
The transform function takes a single parameter: an integer representing which number replication the transform is for. E.g. the first replica to be transformed will be passed the argument `1`. This simplifies your math: the transform function can rely on id `0` being the original instance passed into the `patternTransform`. See the examples.
// Each instance will be shifted along the X axis.
fn transform = (id) => {
return { translate: [4 * id, 0, 0] }
}
// Sketch 4 cylinders.
const sketch001 = startSketchOn('XZ')
|> circle({ center: [0, 0], radius: 2 }, %)
|> extrude(5, %)
|> patternTransform(4, transform, %)
```
 and the first replica
// (at x = 8). This is because `id` starts at 1.
fn transform = (id) => {
return { translate: [4 * (1 + id), 0, 0] }
}
const sketch001 = startSketchOn('XZ')
|> circle({ center: [0, 0], radius: 2 }, %)
|> extrude(5, %)
|> patternTransform(4, transform, %)
```
