Hiding geometry/domains

Hello,

i'm pretty new to comsol. I modeled an IR-Thermopile sensor with the heat transfer with surface-to-surface radiation. In order to realize some convection, the sensor is clouded by air.
Question: How can I make the air invisible for the plots? The air prevents me from correctly viewing whats going on inside the Thermopile.
I've tried to create a new View in which the domain is invisible, but in the end, after computing it is still there.
Got anyone help??

thank you, flo
