I'm working on several Spanish properties and I'm needing to create more elaborate wall structures on some exterior terrain walls, parapet walls, and fireplace walls similar to the images included here. I can create these wall shapes in a 2D CAD view, but I'd like to have a 3D rendering as well if possible. I've attempted and exhausted myself trying to create and position niches and passthroughs to mimic the effects here but I just can't seem to figure it out. Any ideas on how I might create a 3D visual representation of these more elaborate wall shapes? I'm working in Home Designer Pro 2020 on a MacBook and I'm a bit of a novice so please be gentle. Thanks in advance for any and all ideas!
