In a drawing, when creating a cross section view, the "solid" area of the object is filled with a hatch. This hatch is coming in too small, looking like a solid black fill rather than lines. I've been trying to figure out where to adjust this in tools/options or tools/standards and can't find the appropriate setting.  The closes I've found is for "area fill", but that doesn't change the automatic hatch creation from a cross section.

Does anyone know where to find this"?

You can adjust the current hatching by rbm/properties.

The default is set at Styles/Area Fill/Default/Pattern in the drafting standards settings.

You can also add or edit the hatch patterns under "Patterns" in the standards settings.
