Spandrel panel opacity

[Anonymous]

Hi,  I've recently run into a graphic issue with showing two piece spandrel panels in a curtain wall.  To create the spandrel panel i created a wall type with 1 finish being glass, then an air gap, then a layer of metal panel.  When I view the panel in 3D from behind, the metal panel shows up opaque as it should, but head on and the metal panel is transparent.  I've noticed this is just a visibility convention in revit.  Basically when you have a wall type with a void, and your looking at it in 3D (with a section box or some other way of cutting), it shows the opposite side portion of the wall as transparent (if this doesnt make any sense, give it a shot).

Anyway, anyone know a better way of doing this?

Thanks,

To create a spandrel panel, simply select the panel(s) from the curtain wall, and change its (there) type to "solid". It will be opaque from both faces. There is no need to create a different wall type with layers of materials, as you said.

Thanks for your response.  The problem is I dont actually want the panel to just be solid.  I want a layer of glass, then an empty space, and then a panel behind that, creating a shadow box; that is the design intent for this project.  Attached is an image showing the configuration, as well as the problem I'm experiencing.

Thanks,

Change the transparency of the glass in the spandrel panel to 0 (via the material editor).  Unless you're planning to use some kind of backlit/internally illuminated spandrel panel, they're just going to paint the back sid of the glass black anyway.  That should resolve your issue.

Sorry, but that is not what I am trying to do.  It is to be a clear piece of glass with a panel of drywall or metal set back from it, to create a "shadow box."  If you look at the image I think you'll see what I mean.

Then I'm afraid you're out of luck.

Now I understand what you need.

It is possible. You need to create a new family, starting with the Curtain Panel template, and create 2 extrusions. For one of them, select glass. For the other one, assign another opaque material. Then, Load the curtain panel into a project, select a panel in a curtain wall, and assign this family to the selected panel.

See illustration for an example.

I stand corrected, Alfredo.  I assumed that the graphic "error" caused by a Revit would also be in effect for a special panel.  I'm guessing the OP was just using a wall type, which would result in the graphic "error".

No problem, Ross. I understood this the same way as you at the beginning, that the OP was using a wall type.

Let there be spandrel panels! It worked, thanks a lot!

Yeah the solution posed works of the double extrusion but you must leave a gap because when you render in some instances it looks like when someone puts their face against the glass.

Do the double extrusion but leave at least a 10mm gap.
