MODULAR MAGNETIC BLOCK ASSEMBLER

Assemble buildings from your own pieces, block by block

Drop magnetic blocks onto the grid, click a face, and your own piece lands there — facing outward, aligned, exactly where you clicked.

Why I made BlockXQ

I build generators. My other add-on, BuildXQ Craft, stacks a complete multi-storey building for you in seconds — and that is exactly what you want, most of the time.

But a generator decides the shape. Sooner or later you want the L-plan with the setback, the tower on the corner, the courtyard, the arcade under the first floor — and no set of parameters gets you there.

So BlockXQ works the other way around: you decide the shape, cube by cube, and it does the fiddly part. Every piece it places is yours — a window you modelled, a cornice you kit-bashed, a shopfront from your own library.

See it work

Short loops of the real thing. Under each one, the full step on video.

The whole idea. Magnetic cubes on a 3 m grid; click a face, stamp a piece. The cubes are scaffolding — they never render.   Watch the full step ▸

Build the shape first. Blocks snap to the grid and attach face to face — sideways for a wider footprint, on top for another floor.   Watch the full step ▸

Save it as a preset. The recipe, not the geometry — so it is tiny, and the thumbnail is rendered for you.   Watch the full step ▸

A building per click. Tick which presets take part and Random picks one of them each time — a street as fast as you can click.   Watch the full step ▸

A colour per building. One material gives many colours, with nothing duplicated — so a street never looks all the same.   Watch the full step ▸

Your pieces, your style. Publish a model once and build with it forever — names, categories and thumbnails handled for you.   Watch the full step ▸

How it works

1. Shape the volume. Drop and stack magnetic blocks — one at a time, or a whole run in one gesture. Any footprint you can stack.
2. Clothe it. Click a zone of a block and stamp a piece: walls in the middle of a face, columns near the edges, parapets and corners on top, slabs above and below. One click can clothe the whole volume.
3. Vary it. Select a few pieces and swap them all at once for a facade that does not repeat. Hide the scaffolding and the building stands on its own.
4. Keep it. Save it as a preset, give it a colour, and place it again — one click per building, for as long as the street needs.

What's included

Requirements & honest notes

• Blender 5.1 or newer. Installs as an extension — drag the zip into Blender and it is done.
• Developed and tested on Windows. Nothing in it is platform-specific, but that is where it has been used in anger.
• It creates real geometry — your pieces, copied and placed. No procedural black box, nothing to bake.
• Pieces work on a 3 m module. Your own models follow a simple convention (height, facade, origin) that the manual explains in one page.
• Updates are downloaded from your Superhive library, as usual.

FROM THE SAME AUTHOR

BuildXQ Craft v2.0

Want the building generated for you? The parametric generator built around your own models: set floors and width, double-click a wall to swap it, push out bays — five complete styles, a Studio to draw new pieces and a Pack format to share whole styles. It shares the same 3 m module and the same XQ Library as BlockXQ, so buildings made with either belong in the same street. Neither one needs the other.

You bring the style. BlockXQ does the placing.
