##Sverchok parametric tools version - look version file here
addon for: http://blender.org
License: GPL3

###Description Sverchok is a powerful parametric tool for architects, allowing geometry to be programmed visually with nodes. Mesh and geometry programming consists of combining basic elements such as:

• lists of indexed Vectors representing coordinates (Sverchok vectors are zero based)
• lists of grouped indices to represent edges and polygons.
• rotation angles
• matrices (user-friendly rotation-scale-location transformations)

Comes with more than 100 nodes to help create and manipulate geometry. Combining these nodes will allow you to:

• do parametric constructions
• easily change parameters with sliders and formulas
• do cross sections
• calculate areas
• design material
• use Vector fields
• even code your own custom nodes
• and more!

###Installation Install Sverchok as you would any blender addon.

• Installation from Preferences
  Download Sverchok from github
  User Preferences > Addons > install from file >
  choose zip-archive > activate flag beside Sverchok
  If appears error - close and run blender again and activate again.
  Enable permanently in the startup.blend using Ctrl + U and Save User Settings from the Addons menu.

  Use button 'Upgrade Sverchok addon' in sverchok panel in node editor (press N for panel)
  And at the end press F8 button to reload addons. In next blender run in panel will appear new version number

###Troubleshooting Installation Errors We now include NumPy code in Sverchok nodes, this means that you should have an up-to-date version of NumPy on your machine. Normally if you get your Blender precompiled NumPy will be included with Python, however this isn't always the case. If you get an error when enabling Sverchok the last lines of the error are important:

If it mentions

• ImportError: No module named 'numpy'
• multiarray
• DLL failure
• Module use of python33.dll conflicts with this version of Python

then here are steps to fix that.

• download and install Python 3.4.(1) for your os
• download and install numpy 1.8 (for python 3.4) for your os.
• in the Blender directory rename the python folder to _python so Blender uses your local Python 3.4 install.

binaries
python: https://www.python.org/downloads/release/python-341/
numpy: http://sourceforge.net/projects/numpy/files/NumPy/

An alternative is to send a polite email to whoever builds the binary of Blender which you currently use, and inform them that their NumPy inclusion should be double-checked.
