Show Roof Edge Face in Plan

Patrick M — Fri, 13 Feb 2026 01:08:27 GMT

In my roof plan, I have an eave condition that is perpendicular to the roof slope. I need to show the bottom face of the roof in plan, not the top.
It appears there is no way to indicate the bottom face of a roof edge in plan; only the top or edge that overhangs/protrudes.
Any one have a tip or work-around for this? Ideally that does not involve drafting or supplementing with 2d patches. The idea is that the angle of the fascia will change with the roof pitch, and I need to dimension to the bottom edge so that all soffits are the same depth.

Operating system used: Mac Intel-based

I think you will only ever see the bottom edge if it projects beyond the top surface.

Otherwise it will always be hidden and there is no way that I know of to make the top surface transparent.

yeah, I hacked a solution, just tracing the edges with a morph to show in plan... clunky and disconnected, but it is what it is.
I tried to script a custom skylight that would snap to the bottom, but I'm not good enough at gdl to figure out how to keep it from putting phantom openings on my roof

Hi Patrick M,

You can create a 3D document from the Roof Story and set the hidden Edges on for that document.

thats a nice work-around! I've seen people do roof plans with 3d docs before... it seems cringy... but so are many of the work-arounds-turned-solutions...
