A Juliet balcony is a non-trafficable balustrade. There is no platform behind it for anyone to stand on. It lets full-height doors or floor-level windows open safely on an upper level. It is still a barrier across a drop, so it is built to the fall-protection rules that apply where it is installed: confirm them with the certifier for the job.
There are three common ways to fix one. In the reveal, the panel sits between the sides of the opening and is bolted to them through end tabs or full-height jamb plates. Face fixed, the panel is wider than the opening and stands off the outside wall on standoff legs with wall plates, which keeps it clear of render or cladding. On posts, a post at each end stands on the sill or slab on a footplate or in a core-drilled hole. Fixings are usually chemical anchors or expansion bolts into structural brick or concrete. The rail is designed for the full balustrade load even though nobody stands behind it: the worst case is someone leaning hard on it from inside.
CAD60 draws four of them: ornamental, vertical bar, laser-cut and glass. The framed ones set out the bars or the cut-out pattern and draw the fixing you pick: drilled end tabs or jamb plates, standoff legs on wall plates, or posts on footplates or in core holes. The glass one draws the pane with its standoff pins and the holes through the glass.
