What is it?

Sverchok is an addon for Blender that lets architects and designers create geometry through visual programming in a node editor. Meshes, curves, surfaces, scalar and vector fields, and solids are built by connecting nodes, and parameters can be adjusted with sliders or formulas.

The addon includes more than 600 nodes for tasks such as cross-sections, extrusions, CSG booleans, BMesh operations, area and volume calculations, and CSV import. It also offers a Scripted node for custom Python code, Set and Get nodes for accessing Blender's bpy API, and export of SVG and DXF drawings directly from node trees.

Sverchok supports Blender 2.8 and later, including recent 4.x and 5.x releases, and is installed like any other Blender addon. Some optional nodes depend on third-party libraries such as scipy, geomdl and shapely.
