in Autocad Architecture 2010:How can I edit the Hatch that appears in elevation?Thanks,Z

Ok, the problem seem to be only when I select facade view!

You shuold be able to control how the material on your wall behaves.
 
Wall Style Properties>Display Properties, Select wich Display Representation and then click the "A" in the corner.
Thats were you control it.
