Hmm, it looks like the railings will have to be replaced, or at least turned off most of the time. I actually did this for the sub-apartments levels F01-F03 with an “Outer Railings and Ramps” layer for each level, but I didn’t continue it for the higher levels from F04 up, thinking turning off the floors the railings were in was enough.
It seems the floors may need reworking anyway, to fit better with the new plaza walls. This might be the time to redo the terraces with component stringer and include the reduced impact railings in them instead of the overall floor, and plot them with component stringer too. I believe when I was looking at the component browser’s details I saw a railing with over 7,000 edges alone, so that could be a major issue if accumulated. Low walls around all the terraces would have been a lot simpler and easier to create, but would have meant a more uniform appearance without differentiation on the terraces so easily observable. Also, a thicker wall vs. a thin metal railing.
I’m still a bit surprised it is such an issue, particularly in a much smaller model, since I just went through levels F49-F75, fixing the inner courtyard separator walls which are perpendicular to the F34 - Mid-courtyard apartments wall (see below about renaming this), which meant turning on all those floors including railings and I had no real difficulties other than momentary video lags. Of course, I went through your levels to do that too, but I was working on the floors only. I can re-export those for you if you haven’t already worked on them, or else re-replace the separator walls into your submodel before I import it into the main model.
The inner courtyard terraces on the outer side were a mess and had to be worked on as part of the whole, including renaming the F3 - Mid-courtyard apartments wall to F34 - Mid-courtyard apartments wall, which reflects the level it actually started on. I can make this change to your submodel too unless you can do it.
As you can see, it is quite difficult NOT to work on the levels overall when fixing things, so I hope your submodel work will not take too long.
But I will try to focus on the higher levels today. I’m on F76 floor now and should be able to knock that off pretty quickly and then make further adjustments to the edge apts. on F77, then go up again from there.
Anyway, continue what you’re doing, but realize that the plaza terraces, at least, will all have to be redone not just for the railings, but for size and position relative to the plaza walls and the adjusted floors behind them, done by either you or me.
End of night shift.
