Exampletsx

import { CursorDraftingArm } from '@/components/ui/cursor-drafting-arm'

export default function CursorDraftingArmDemo() {
  return (
    <div className="relative min-h-[560px] overflow-hidden">
      <CursorDraftingArm anchor="bottom-left" showLabel />
      <div className="pointer-events-none relative mx-auto flex min-h-[560px] max-w-3xl flex-col items-center justify-center px-6 py-24 text-center">

        <p className="mt-4 max-w-md text-sm leading-relaxed text-muted-foreground">
          A drafting arm bolted to the corner solves real inverse kinematics so the pen tip
          always finds your hand, elbow bowed to the edge, never the center.
        </p>
      </div>
    </div>

Related components

Survey Crosshair

Full-viewport drafting crosshair, hairline axes track the pointer with mono coordinate readouts in the margins, and hovering targets snaps brackets around them.

Measure Tape

Hold and drag to pull a live measuring tape, a ticked hairline from drag origin to pointer with a mono px readout and angle that evaporates on release. A drafting instrument as play.

Echo Rings

Every click drops a stone in the page, concentric hairline rings ripple out from the point and dissolve, with a soft accent pulse at the center. Sonar for the UI.

Pointer Galvanometer

A docked galvanometer meters the pointer, a ballistic needle kicks across a graduated arc with cursor speed, a primary peak-hold tick decays behind it. React + Tailwind tokens.

Glyph Wake

The pointer leaves a wake of mono glyphs, characters condense along the path, hold for a breath, and evaporate. Typography as vapor trail.

Goo Cursor Trail

A chain of accent blobs chases the cursor through an SVG goo filter, merging, stretching, splitting like liquid ink. Touch devices get an autonomous lava-lamp drift.

Frequently asked questions

How do I install the Drafting Arm component?

Register the @cleverui registry in your components.json ("@cleverui": "https://cleverops.com.au/r/{name}.json"), then run `npx shadcn@latest add @cleverui/cursor-drafting-arm`. The shadcn CLI copies the source into your project, you own the code from that point. You can also copy the source directly from this page.

What dependencies does Drafting Arm require?

Drafting Arm uses motion on top of React and Tailwind CSS. You don't need to install it manually, the shadcn CLI resolves and installs npm dependencies automatically when you add the component.

Can I theme Drafting Arm to match my brand?

Yes. The component is styled entirely with Tailwind utilities over standard design tokens (primary, background, muted, border), so it inherits your existing shadcn/ui theme automatically. Change your CSS variables and the component follows, no source edits needed for palette, radius, or fonts.
