CobbleDraw is a Geometry Nodes setup that allows users to generate cobblestone paths and surfaces by drawing curves directly in the Blender viewport. The system projects filled curves onto a designated target surface to procedurally generate actual 3D stone geometry along the drawn path. Users interact with the tool using Blender's native curve drawing features and curve pen tools in Edit Mode.

The tool includes a custom node group, a procedural stone shader, and a customizable mud material. Through the modifier panel, users can adjust remeshing settings and stone diameter to fill gaps in their paths. The setup also provides controls for dirt height and color, and allows users to substitute their own dirt and mud materials via a provided mask in the Shader Editor.
