FROM FILE TO FINISHED BUILD

A workspace built for builders.

Keep your model, layer plan, and building progress together while you bring your structure into the game.

01

See the whole structure

Open your build in the 3D viewer. Inspect its shape, measure distances, and review the blocks you need.

02

Focus on the next layer

Break a large build into manageable layers. Follow the plan one level at a time instead of keeping the entire structure in your head.

03

Pick up where you left off

Mark your building progress as you go. Keep track of the blocks you place and return to your plan for the next session.
