string - A sequence of characters
Examples
startSketchOn(-XZ)
|> circle(center = [0, 0], radius = 10)
|> extrude(length = 4)
|> appearance(color = appearance::rgb([50, 160, 160]))
sideLen = 30
n = 10
// The cubes become more green and less blue with each instance.
fn cube(i, center) {
g = 255 / n * i
b = 255 / n * (n - i)
return startSketchOn(XY)
|> polygon(radius = sideLen / 2, numSides = 4, center = [center, 0])
|> extrude(length = sideLen)
|> appearance(color = appearance::rgb([0, g, b]), metalness = 80, roughness = 20)
}
// Create n cubes, shifting each one over in a line.
