I am not sure if what I am trying to do is possible without using Arcobjects, but what I want to do is use a piece of a prebuilt addin created by ESRI and then add it into my own Arcpy script. The specific addin is the Curves and Lines addin and the Curvinator functionality is what I am after. I know it is possible to call a script from within another script but I can't figure out how to call the toolbar button from within a script or whether it is even possible. The addin is available at http://www.arcgis.com/home/item.html?id=b59665cb906a435da3f8c45332d7cfdf.

The Curves and Lines add-in is not a python add-in. It is probably a .Net ArcObjects add-in.

I determined this by downloading the add-in and extracting the files using an unzip application. Inside I only found .dll and related files, no python files. A Python add-in would include the .py files.

If it were a Python add-in it would be possible to extract the .py file from the add-in and reference that from your script.

It is possible to call ArcObjects from arcpy, and you may be able to use that to access your add-in tools.
