Create Axes Model using CreateModels CLI

Development

It is not a CLI module but a loadable module. You can verify that by printing the module’s class name:

>>> slicer.modules.createmodels.className()
'qSlicerCreateModelsModule'

You can use loadable modules by calling methods of their logic class:

logic = slicer.modules.createmodels.logic()
logic.CreateNeedle(100,5,0,True)

To get a description of all methods and their parameters, type help(logic) and you get a description like this:

class vtkSlicerCreateModelsLogic(vtkSlicerModuleLogic)
 |  vtkSlicerCreateModelsLogic - slicer logic class for creating simple
 |  models
 |  
 |  Superclass: vtkSlicerModuleLogic
 |  
 |  This class contains methods that create model nodes useful for
 |  setting up IGT scenes. These methods can be called from other
 |  modules.
