I needed a way to show X Hatch, on a drawing, in 'openings' (Through All) on a part.

I searched this site but I couldn't find anything.

So I same up with this technique using sketches and X Hatch.

1/ click on the view to activate it.

2/ select ‘Sketch’, Convert Entities, with Select Chain & Inner loops one by one selected.

3/ select one line and the loop is highlighted, then ‘accept’

4/ select ‘Annotations’, ‘Area Hatch/Fill’ , ‘Boundary’ , select with window then delete 'Face' from the list. 

5/ Accept. (X Hatch is added)

The top shape on the edge works as well. A sketched horizontal line was added to complete the loop

It goes pretty fast once you do it a few times, like most things.

If there is a better way, I would love to hear about it.
