Hi All
Can some one please help me
I think I am missing something.

I have created a new window, this is a simple 3d block with a frame and sash converted to mass elements with the glass as a solid.
I have drawn blocks for the elevation and plan and end views.
I have attached the materials to the elements.
The window works fine in model space and the materials and glass work fine in realistic visual style.
when I go to view tab and generate the elevations the windows work fine, but I can see objects behind them, as the glass is clear.
obviously I dont want to be able to see the walls and doors behind in the elevations
How do I make the glass opaque in the elevations and clear in the model when the visual style is realistic.
I know this can be done as the windows supplied with ACA do this,
My settings in style manger are exactly the same as the settings for the windows supplied in ACA
I think that the problem is with the block I created for the elevation but Im not sure

Any help greatly appreciated
