Using PyCharm with QGIS 3? Follow

I've just changed to QGIS 3 and I can't figure out why I can't change from Python 2.7 to Python 3.6 in PyCharm, njmcdirect keep getting invalid SDK! I run this .bat-file:

SET OSGEO4W_ROOT=C:\OSGeo4W64
SET QGISNAME=qgis
SET QGIS=%OSGEO4W_ROOT%\apps\%QGISNAME%
SET QGIS_PREFIX_PATH=%QGIS%
SET PYCHARM="C:\Program Files\JetBrains\PyCharm 2017.1.2\bin\pycharm64.exe"

CALL %OSGEO4W_ROOT%\bin\o4w_env.bat

SET PATH=%PATH%;%QGIS%\bin
SET PYTHONPATH=%QGIS%\python;%PYTHONPATH%

start "PyCharm aware of QGIS" /B %PYCHARM% %*
