Can I hatch a 3D solid surface Do I have to create a 3D face on top of it beforehand Would like some tips on how to begin.

Once the UCS is aligned with the face, you will need to trace around the face with a polyline.

I did try a polyline perimeter on the face, but when I did the hatch selection Im sure I clicked on the middle of the face and not the polyline.

Nor did I want a contractor to think he had to lap-side the inside of, say, a garage.

Did I make a wrong assumption about a Material type permeating an entire solid Would love to hear otherwise.

Below I have applied several different materials to a box using this method.

I changed the alignment, did the polyline perimeter, clicked on it, and Voila, theres my hatch pattern.

Did I mention that it wound up in outer space, about twenty or thirty yards from the outside surface of the house wall Used the Move command to move it toward its target where it now sits about six inches higher than it should.

I think that in the book I skimmed the Materials section was focused on a house foundation.

And of course the author would have wanted the entire solid -- ALL the foundation -- looking like concrete, not just one surface.
