Reticle Studio

Design a custom rifle-scope reticle right in your browser — crosshairs, BDC ladders, christmas-tree holds, chevrons and more, all to exact MIL/MOA subtensions. When you're done, export it as a file or grab a short code to load it straight into the Zima Ballistics app.

Reticle Studio is a brand-new feature under active development — things may change and you might hit the odd rough edge. Spotted a bug or have an idea? Let us know.

How to use Reticle Studio

Presets & the Library

The built-in Presets are independent approximations of third-party reticles — Trijicon (ACOG), Leupold, Horus (TREMOR 3) and ELCAN — handy starting points.

The Library goes further: a growing set of real-world reticles, grouped by brand, each rebuilt to match the manufacturer's own published subtension figures so the geometry is accurate to spec. A ~ next to a name flags an entry still pending a final review; the rest are verified against the source figures. Open any of them and edit it like anything else. Zima is not affiliated with these brands and they have not provided reticle data; everything is reconstructed from published figures for visualization.

The basics

Add an element — open + Add and choose a shape (crosshair, dot, hash ladder, chevron, christmas-tree, BDC ladder, label, and more). It drops at the center.
Select & edit it — click the element on the canvas (or in the left Elements list). Its settings appear in the right panel — sizes are in MIL/MOA to exact subtensions.
Position it — drag the element on the canvas. It snaps to a fine grid, and locks to the center axes (you'll see a blue guide line) when it's close.
Start from a preset or the Library — Presets are quick example reticles; the Library has real-world reticles rebuilt to exact published subtensions (see above). Either one loads as a fully editable starting point.

Zoom, move & select

Zoom: scroll your mouse wheel / trackpad over the canvas (zooms toward the cursor), or use the + / − buttons (the fainter pair below them is fine ±1% zoom). The ⊕ button (or F) re-centers and fits the view.
Move / pan: hold Alt/Option and drag, or drag with the middle mouse button. Arrow keys nudge the view too.
Select: click an element. Cmd/Ctrl+click adds more to the selection; click empty space to deselect.
Reorder / group: drag rows in the Elements list to change draw order; select several and group them.
Touch: on a phone or tablet, pinch to zoom and drag to pan the canvas.

Keyboard shortcuts

`Cmd/Ctrl` + `Z`	Undo
`Cmd/Ctrl` + `Shift` + `Z`	Redo
`Backspace` / `Delete`	Delete selected element
`Arrow keys`	Pan the view
`F` / `Home`	Fit & recenter
`+` / `−`	Zoom in / out (`]` / `[` = fine)

Reference image & finishing

⊞ Ref loads a photo or PDF of a real reticle to trace over — adjust its opacity/scale and lock it in place. It never appears in your exports.
FOV sets the scope field-of-view the reticle is designed for (this is metadata — separate from how far you're zoomed in).
Export when done: save an editable .reticle.json, an SVG/PNG image, or send it to the Zima Ballistics app two ways — Get Share Code (a 6-character code that loads on web, iOS and Android), or download the iOS + Android reticle file, a single export that works in both apps (no need to export twice).

Tip: hover any button or field in the builder for a one-line explanation.
