In ANY elevation view, materials are not transparent as see in this first image (does not matter what the Visual Style is set to).

Even turning off the glass Material (i.e. sub-category) in VV will not allow you to see through the “opening” as seen in this next image.

The trick here is to edit the Opening Cut element in the family so it is transparent in elevation. Simply select the opening and check “elevation” on the Options Bar as shown in the image below.

| Set Opening to Transparent in Family Editor |
Once the opening is set to be transparent in elevation and the glass sub category is turned off you can see though the windows as shown in the image below.

Another option is to adjust a 3D view to “front”.
This is a flat view, just like an elevation, but is still technically still a 3D view. You can lock the view and add dimensions, tags and notes. But you will not get grids and levels. Turn on the Section Box and you will even get the toposurface in section.
