Roof Fascia Modeling

Is there a straightforward way to square off the bottoms of fascias in Archicad?

I've searched for a solution but haven't found a clear answer. As shown in my screenshot, I need the fascia bottoms to be squared off. It seems like this could be a simple feature within the custom edge settings but unfortunately there isn't an option. Currently, I’m using slabs on a hidden layer with solid element operations as a workaround, but this method can become quite messy. Since majority of my projects require this look, finding a more efficient solution would be incredibly helpful. If anyone has suggestions or best practices for achieving this more easily, I’d really appreciate the help.

Use a beam. You can change the ends using

If you work on Archicad 28, you can also place Openings into the Roofs to achieve the horizontal bottom cut of the Fascia. The Openings will be associated with the Roof.

Typically I'll use beams for my fascia, and assume the flat piece of fascia would "stop" the angled portion, meaning it would have about a 1" horizontal piece, or whatever thickness your fascia is. This is achieved using 3 beams per the screenshots below. To get the look you need per your screenshot, with the angled piece coming out to the face of the horizontal, the SEO trick mentioned by others is a workaround, as is modeling the angled portion with a custom profile beam and extruding it the thickness of the fascia.

If you place the Reference Line on the other side of those Beams, it will be easier to model them.

That is also a possibility but you need some amount of length of the smaller horizontal beam (non-highlighted portion shown 1/6" long below) to cut off angle, so the face of the angled fascia would never truly touch the face of the longer horizontal. I have the reference line where shown because when modeling trim, I usually put the reference line in relation to the "static" corner of the beam. In this case, if I ever wanted to quickly change the size of the fascia, I would want it to grow "down" and "out", away from the upper corner where my reference line is, if that makes sense. If placing baseboard with a beam, I would want it to grow "up" and "out".
