Why BlockShape

Less guessing. Cleaner builds.

Square blocks make straight lines easy and curves difficult. A generated blueprint replaces repeated rebuilding with a centered, repeatable pattern. BlockShape calculates the occupied cells, keeps every layer aligned and shows both the current-layer and whole-project block counts.

The graphics are original, generic square-grid and voxel visuals. No game files, textures, logos, login or installation are required. The same tools can also be used for voxel art, pixel mosaics, bead patterns and other grid-based projects.
