According to SW help, you should be able to hatch a cross section by clicking on insert/annotations/area hatch/fill.  But when I do this the area hatch/fill option is always greyed out . . . so you can’t select it.  This is supposed to work independent of Materials properties (i.e. you can use this approach to hatch something that has no material properties assigned).  I tried assigning materials properties and this has no effect either.

Everything seems to be set up OK but . . . no dice.  Any ideas??

I'm using Solid Works 2010

Thanks
