AutoCAD 2006

After hatching with the two-color gradient hatch, I copied and rotated the hatched area to a different file and the pattarn kept the original angle. In the original location, the two color pattarn are white and grey (grey on both sides and white in the middle - second gradient option in the list). This pattarn is vertical. When it was copied to another file and rotated, the grey colors kept the verticality instead of rotating to the new angle. Is this how it is supposed to be? This will be a problem with shading or adding a quick shadow.

Is there a way to control it's direction regardless of what the new copied angle might be?
