Description

Sverchok is a powerful parametric tool for architects and designers, enabling visual programming of geometry through nodes. Mesh and geometry programming involves combining basic elements such as:

• Lists of indexed vectors representing coordinates (Sverchok uses zero-based indexing)
• Lists of grouped indices representing edges and polygons
• Matrices (user-friendly rotation-scale-location transformations)
• Curves
• Surfaces
• Scalar and vector fields
• Solids
• Insolation and solar heating calculations

Features

With over 600 nodes for creating and manipulating geometry, combining these nodes enables you to:

• Create parametric constructions
• Easily adjust parameters using sliders and formulas
• Utilize powerful nodes including: Profile parametric, UVconnect, Generative art, Mesh expression, Proportion edit, Wafel, Adaptive Polygons (tissue vectorized), Adaptive edges, ExecNodeMod, Vector Interpolation series, List manipulators, CSG Boolean, Bmesh operations, Bmesh properties, and more
• Perform cross-sections, extrusions, and other modifications with flexible, parameterized, and vectorized node tools
• Calculate areas, volumes, and perform other geometric analysis
• Create or import CSV tables and custom formats
• Work with vector/scalar fields—create them and visualize data
• Perform solid modeling
• Code custom nodes in Python using the Scripted node
• Create custom 'addons' based on node layouts and integrate them into your workflow via Sverchok's 3D View panel
• Access Blender's Python API (bpy) with specialized Set and Get nodes
• Update Sverchok with a single click
• Incorporate genetic algorithms into your workflow
• Perform insolation/radiation calculations
• Export SVG/DXF drawings directly from node trees
• Exchange BREP/NURBS/IFC data
• And much more!

Installation

Install Sverchok like any other Blender addon.

• Installation from Preferences
  Download the Sverchok archive (zip) from GitHub

  • Do not unpack the archive after downloading — Blender will handle this
    • Mac OS users may need to recompress the folder if Safari automatically extracted and deleted the .zip
  • Go to Edit > Preferences > Add-ons
  • Click the Install... button
  • Browse to the zip file location, select it, and click "Install Add-on"
  • Blender will unpack the addon and present an option to enable it
  • Enable it by checking the box next to Node: Sverchok
  • Allow Blender a few seconds to complete the installation
  • When complete, Blender will display:
    • Node: Sverchok

  By default, Blender (version 2.80 and above) will remember enabled addons for future sessions.

• Updating Sverchok
  Use the Check for new version button in Sverchok's panel in the Node Editor (press N to open the panel)
  Click the Update Sverchok button
  Press F8 to reload addons—the new version number will appear in the N-panel

• Additional Dependencies
  Sverchok provides many features out-of-the-box, but additional nodes and scripts utilize third-party libraries including:

  • scipy
  • marching cubes
  • geomdl
  • SciKit-image
  • shapely
  • circlify
  • freecadpython3lib

  Installation instructions for these dependencies are available on this wiki page

Troubleshooting Installation Errors

If installing from a release zip containing a folder named sverchok-master.x.y.z, rename it to sverchok-master since folder names with dots are invalid Python package names.

If using releases from here, note that these versioned zips are intended for testing older Sverchok versions with legacy .blend files and Blender versions, not for initial installations.

Errors during installation or enabling

If you encounter errors like:

NameError: name 'nodes' is not defined

Exit and restart Blender, then enable Sverchok again. The addon may take up to 10 seconds to initialize depending on your system performance.

Other installation issues

If Sverchok still fails to install, we've compiled troubleshooting solutions here. Please report any new issues you encounter.

Updating via the in-panel button may fail if you've renamed the installation folder. Follow this guide for a bootstrap script solution.
