Hello I'm new in blender api. I know python good but I can't start to make some changes for example with Screw modifier. How to edit the source on this type or try to write own version of this modifier. I found definition in:
2.71/scripts/startup/bl_ui/properties_data_modifier.py
I found in doc http://www.blender.org/documentation/blender_python_api_2_71_release/bpy.types.ScrewModifier.html?highlight=type%20screw#bpy.types.ScrewModifier but cant find in blender files the class implementation.
