Studwork: Brick Model Builder

Design brick models on your phone or tablet.
Studwork is a full construction editor that runs offline. Place parts on the stud grid, move, rotate, mirror and copy them, and build whatever you have in your head — with 18,431 parts and 322 colours already in the app. Nothing to download, no account, no connection needed.

Opens the files you already have.
Studwork reads and writes .io, .ldr and .mpd files, so a model you started on a desktop opens on your phone and goes back again unchanged. It also reads .lxfml and .lxf files for their parts and colours.

Turn a photo into a brick mosaic.
Choose a photo and a size in studs. Studwork builds it as a flat model of 1 × 1 plates or tiles on backing plates, with its parts list and its steps, and you edit it like any other model.

Get the model out.
A parts list grouped by part and colour. Step-by-step instructions you can follow on the device. A high-resolution render of the finished model — on a background colour you choose, or on no background at all.

Everything in the editor is free.
The whole editor, every part, every colour, unlimited models, no part limit, no watermark — and every file Studwork writes: .io, .ldr, .mpd, the parts list, the instructions and the render. There is one banner, on the model list only, never on the canvas, and it does not appear until you have saved your first model.

Studwork Pro is one payment, not a subscription.
It removes that banner. That is the whole of it; the app is otherwise identical either way.
