How to put a n6 fit on a turned shafts outside diameter

Hi,

I would like to put a tolerance on the diameter of this shaft because this shaft will go into two bearings with a press fit.

SO the shaft needs a n6 fit.

Because I have drafted it via a halfmodel, I can't put a measure on the outside diameter of the shaft.

The diameter is 85mm. I have already tried it with drafting a line to the middle, but 32,5mm is obviously a much smaller tolerancefield than 85mm.

I need to use the diameter.

Is there any way to do this on a turned part from a halfsketch?
