The GenericToolkit module, available from the Python API of Sim4Life, interfaces with most of the templating tools of the GUI.
One can for example use it to interface with the Coil Template tool to generate all sorts of coils, as in the example below:

import GenericToolkit
import s4l_v1.document as doc


## Solenoid, circular
newcoil = GenericToolkit.Create('Coil')

newcoil.Parameters.Geometry.CoilGeometry.Spatial.Value = 1  # {0: u'Flat', 1: u'Solenoid'}
newcoil.Parameters.Geometry.CoilGeometry.Shape.Value = 1    # {0: u'Rectangular', 1: u'Circular'}
newcoil.Parameters.Geometry.CoilGeometry.Figure.Value = 0   # {0: u'Helix', 1: u'Parallel Circles'}
# newcoil.Parameters.Geometry.CoilGeometry.Figure.Values    # list all available values (in the console)

newcoil.Parameters.Geometry.CoilProperties.Radius.Value = 50  

newcoil.Parameters.Geometry.Layers.NumLayers.Value = 6
newcoil.Parameters.Geometry.Layers.Thickness.Value = 12

newcoil.EvaluateParameters()



## Solenoid, square
newcoil = GenericToolkit.Create('Coil')

newcoil.Parameters.Geometry.CoilGeometry.Spatial.Value = 1  # {0: u'Flat', 1: u'Solenoid'}
newcoil.Parameters.Geometry.CoilGeometry.Shape.Value = 0    # {0: u'Rectangular', 1: u'Circular'}
newcoil.Parameters.Geometry.CoilGeometry.Figure.Value = 0   # {0: u'Helix', 1: u'Parallel Circles'}

newcoil.Parameters.Geometry.CoilProperties.Width.Value = 50  
newcoil.Parameters.Geometry.CoilProperties.Length.Value = 70  

newcoil.Parameters.Geometry.Layers.NumLayers.Value = 3
newcoil.Parameters.Geometry.Layers.Thickness.Value = 4

newcoil.EvaluateParameters()


## Flat, circular
newcoil = GenericToolkit.Create('Coil')

newcoil.Parameters.Geometry.CoilGeometry.Spatial.Value = 0  # {0: u'Flat', 1: u'Solenoid'}
newcoil.Parameters.Geometry.CoilGeometry.Shape.Value = 1    # {0: u'Rectangular', 1: u'Circular'}
newcoil.Parameters.Geometry.CoilGeometry.Figure.Value = 0   # {0: u'Helix', 1: u'Parallel Circles'}

newcoil.Parameters.Geometry.CoilProperties.NumTurns.Value = 10 
newcoil.Parameters.Geometry.CoilProperties.InnerRadius.Value = 25  
newcoil.Parameters.Geometry.CoilProperties.OuterRadius.Value = 45  

newcoil.Parameters.Geometry.Layers.NumLayers.Value = 1

newcoil.EvaluateParameters()


# Print all available properties in the Console
print newcoil.Parameters.DumpTree()
