    How would you go about modeling this shape?

    We have a large facility with about 12 different roofs with parapets. Some of these parapets step down (at varying dimensions) to follow the slope and at these points need a sort of end cap so you're not looking into the wall cavity as seen in the image.

    In real life the parapet cap will step down with the parapet in sort of a continuous cascading pattern. We are trying to model this realistically by creating the shape that fills in that vertical portion. I first did this with an extrusion but it looks off due to it's flatness (boss also wants the overhangs to follow the vertical path down to meet the next cap). Note the rounded edges on the overhang, both the front and back have that profile.

    I dont know how to to make those rounded edges follow the verical edge and the horizontal edge, when working with the extrusion I can only draw arcs on the shape on one plane. This extrusion was also parametric allowing me stretch the vertical size of it to fit the different locations.

    My latest attempt was a sweep, the sweep transitions all the rounded edges perfectly but the issue is that it also brings the slope of the parapet cap down the vertical plane, which in real life would never happen. It also is not parametric.

    Any advice on this would be incredibly helpful and appreciated.

    Not a 100% sure what you wanna do, but I'd say Void Sweeps to round of the edges. You can pick 3D edges to place them on.

      Thanks for the response, I can apply a void sweep to existing extrusion?

          A recent project had a stepped parapet similar to what you described. In our case the horizontal and vertical elements had the same profile so they were modeled as horizontal and vertical sweeps. Dragging the end points of the sweeps will clean up the intersections.
