boxblock

a 3d block modeller that feels part minecraft, part fast blockout tool. build directly in the world, swap between multiple block sizes, paint surfaces, carve forms, fill volumes, extrude shapes, copy structures, and keep working in one tab.

build / shape / paint

full, half, quarter, tiny, and bit blocks ; fill, line, ellipse, move, pick, paint, copy / paste, and truss tools ; connected delete and carve variants for fast cleanup ; top down mode for cleaner drafting and layout work.

worlds / terrain / layout

flat, void, and heightmap worlds ; grayscale terrain generation ; in-app terrain sculpting ; custom stamps for repeatable detail ; blueprints for reusable builds ; tpll for projecting pasted real-world coordinate strings into the world as footprints and site layouts.

save / load / export

browser autosave and local worlds ; json import & export for editable saves ; glb export for model output ; palette, stamp, and blueprint workflows for moving assets between sessions.

tips

fill F -> erase X for fast carving

fill F -> extrude R to push layers

pick Q grabs blocks straight from the world

copy C -> paste V -> repeat with [ ] or save as a blueprint

SHIFT + TAB opens top down view
