Picture Stroke for Extruded Polygon

[MeleKoneya]

Good morning,

I am trying to add a picture stroke to an extruded polygon and am not have any luck.

As a matter of fact, changing the outline to a solid stroke does show up

What I was able to do is copy the layer and draw just the outlines of the polygons.    However I am not able to change much about the line symbol except for the color 

Is there a trick to making the lines show the properties I'd like?

Thank you,

Mele
