Transforms

Transforms move, rotate, and mirror existing geometry in 3D space.

Translate

Move a solid to a new position:

import { cylinder, sphere, translate } from 'fluidcad/core';

cylinder(50, 100)
sphere(50)

translate([150, 0, 0], true, cylinder)

Signatures:

translate(x, y, z)                 // move by x, y, z
translate([x, y, z])               // same, with an array
translate([x, y, z], true)         // copy instead of move (keeps the original)
translate([x, y, z], true, target) // copy a specific object

The third argument true creates a copy — the original stays in place and a duplicate appears at the new position.

Rotate

Rotate geometry around an axis:

import { axis, extrude, rect, rotate, sketch } from 'fluidcad/core';

sketch("xy", () => {
    rect([100, 100], 200, 100)
})

extrude(20)

const a = axis("z", { offsetX: 90, offsetY: 90 })

rotate(a, 90, true)           // rotate 90° around the axis, keep original
rotate(a, 180, true)          // another copy at 180°

Defining axes

import { axis } from 'fluidcad/core';

axis("x")                                 // X axis at origin
axis("z")                                 // Z axis at origin
axis("z", { offsetX: 50, offsetY: 30 })   // Z axis offset from origin

Mirror

Mirror geometry across a plane:

import { extrude, mirror, sketch } from 'fluidcad/core';
import { rect, move } from 'fluidcad/core';

sketch("xy", () => {
    move([10, 0])
    rect(50, 30)
})

extrude(20)

mirror("yz")                   // mirror across the YZ plane

You can use any plane name ("xy", "xz", "yz", "front", "top", "right", etc.) or a custom plane() object.
