Floating Linear Fireplace HELP

[Atelier]

Hello All,

I am very new to CA, having taught myself since working for another company in March 2025. I am trying to design a 360° floating linear fireplace that will appear to suspend from the ceiling, with a tempered glass, recessed toe kick, and a ledge to sit on, wrapping around a 360° fireplace. This is not a typical fireplace; it's an aqua fire insert that doesn't produce heat and will be encapsulated in glass for a see-through design. I've tried using polyline solids, but I can't get the subtraction to work when creating the 12x24x80 cutout. I've watched many videos and am completely confused! Some videos suggest using primitive polylines with a window for the cutout or a soffit for the ledge, but CA17 only offers a solid box option. PLEASE HELP! I am on a deadline and frustrated. I have attached my progress, but the framing, electrical, plumbing, etc., layers aren't populating when I select them to send to my GC. Also, the fireplace insert is missing. I appreciate any help, as I am new to this software and self-taught!

Using a polyline solid, make the box you want to subtract an inch or two bigger than the object it is being subtracted from.  For instance, if the opening you need is 12 high x 80" long, in a box that is 24" deep, then make the box you will be subtracting 28" deep (extending 2" past the polygon to remain in the front & rear directions)  

This is the result after I added (4) "Fire 6" objects from Modern No.1 Fireplaces Library (evenly spaced to give the 2D fire depth.).

Additionally, that same library has a couple of glass fireplaces that appear similar to what you've described.  I added 3D "Flame 6" to both fireplaces.  

 

I really can't tell what you are trying to achieve from your description and PDF.  From the Aquafire website, These images are 3 sided, not four sided

 

This image is 4 sided, but lacks any glass detailing around the fireplace

 

This image is see-thru, which is similar to what I drew using poly object subtraction
