I'm trying to set up auto complete for ArcPy in PyCharm, but while submodules seem to have auto complete suggestions, the ArcPy module itself doesn't have completions provided.
Example of unsuccessful auto complete:
But when typing arcpy.gp. I see suggestions, as expected.
I thought that the submodules and functions/classes directly available from arcpy would be shown or help for specific functions would display.
I followed the instructions for setting up PyCharm to reference ArcPy. I ensured that the project interpreter was configured correctly, and also my PYTHONPATH in the application. I have also tried invalidating the cache and restarting PyCharm but did not see any improvement.
Is this auto complete supposed to work, and if so, how do I configure PyCharm to do it?
I am using PyCharm Community Edition 2016.2.3 and Arcpy as included with ArcGIS Desktop 10.3.

arcpy. If you wait a few seconds, does that help? – Paul Nov 16 '16 at 23:21
