Currently, in high LOD (Level of Development) projects, we have to rely on complex workarounds to represent straight runs of wire mesh trays. None of these methods provide an efficient workflow. While there are external libraries or custom fitting families, using them requires entirely manual placement. In contrast, native cable tray families allow us to configure routing preferences, making the creation, insertion, and editing of fittings automatic and seamless.
I noticed a similar request was made years ago but was archived due to a lack of community engagement at the time. However, demanding project requirements have evolved, and there is no longer a reason to keep this out of the software's default library.
From a user perspective (without diving into programming complexities), the straight sections of a wire mesh tray could follow a similar logic to the native "Ladder" cable tray: the horizontal rungs would act as the bottom support wires, and the vertical sides would simply be longitudinal wires extending along the run. Since the foundational logic for structural patterns in trays already exists, implementing this shouldn't be an insurmountable challenge. Furthermore, a quick search on YouTube shows that designers are forced to invent completely different, unstandardized methods to visually represent these trays.
While some might see this as a minor visual detail, it becomes a major bottleneck in high-stakes projects. I believe the historical lack of community traction is simply because not every company requires this level of detail, and not every designer prioritizes visual fidelity. However, when a BIM modeler is required to deliver this LOD, they face a frustrating choice: either waste hours using tedious workarounds that slow down the entire modeling process, or settle for a standard solid-walled tray family, sacrificing visual accuracy.
As a user, I may not understand the underlying development effort, but I am confident that adding native wire mesh trays would be a quality-of-life improvement. It would save hours of modeling time and finally standardize the representation of this widely used electrical component.
