Curtain Wall - Adding a Shadowbox/Metal Panel Within the Curtain Wall


I manually created this curtain wall in Rhino but was trying to figure out how to replicate this in visual arq. Is there a way to add a shadow box/aluminum panel within a curtain wall system like in this image here?

You can create that “shadow box” with a Support component that uses a custom profile. You can previously create the custom profile with the vaProfileFromCurve command.
However you cannot have only the top support, as indicated in this other thread: Curtain Wall - Adding Top and/or Bottom Support
But as mentioned there, alternatively you can create that curtain wall as a window from a Grasshopper style.
