Thanks for your quick replys. I actually found exactly what I was looking for.
Millworks>Wall Panels & Niches> Wall Niche
I added that to my exterior wall and just gave it the same stucco finish I had. I call that a faux window stucco feature.
I'm using Home Designer suite 184.108.40.206
Are there any feature templates for exterior walls like a false window feature for example? Or is there any easy way to do this? I can't seem to get the arch right from the geometric shapes.
