Grid Modeler is a direct modeling tool that introduces a draw-based workflow to Blender. It allows users to create 3D models by drawing shapes on an advanced, rotatable grid plane and using them for boolean cuts or mesh creation. It is designed for speed modeling of static objects, hard surface designs, and mechanical parts.

The tool features powerful shape functions, boolean slicing, construction lines, and the ability to pipe geometry. Users familiar with CAD software may find the workflow intuitive as it relies on drawing and extruding shapes directly. The addon operates destructively, applying boolean operations directly and resulting in n-gons.
