Linked Model Wall Fills

[TerribleTim]

Hey gang,
Next dilemma - ;)

I've got a Structural Model linked into ours. For what ever reason it shows with a wall fill. I tried looking in the Vis Graphics for a spot to turn it off but I can't find it. If I go in Vis Graphics, under the linked model, under WALLS, the little override box for patterns on both projection and cut is greyed out. Can you guys point me in the right direction?

Nevermind, I found it. I was looking at the WALL sub-categories. But the WALL category itself let me turn it off.
