How to Hatch an area in Drawing?

Hi,

So if u imagine iam dealing with a 1'' OD pipe, and iam trying to hatch the inside area of the ID, thus, there is no section, this is only for a representational purpose. How could I hatch that center area? SW is not letting me do, it only let me choose's the area inbetween the inner and outer diameters.

Thanks for ur help.
