Jan/Richie, I only added the wedge to fill the space that is missing from the existing layout and shelf. It and the lift-out can be any size/shape that works.
Just don’t forget that the new tracks might need a filler in the upper right in order to connect to the existing O36 switch. I’d hate to see you start laying tracks from the switch and then find they won’t connect.
To be honest though, the measurements must not be accurate because everything connects with the O36 curve and straight that are there now, so they should connect when those are replaced by the O36 switches. Those should be a direct replacement and fit right in.
I hate to harp on this, but it’s a discrepancy and I don’t want there to be any surprises. The software can only go with dimensions provided. And it doesn’t really matter as long as you’re aware of it in case the replacement tracks don’t line up like I think they should. At any rate, you have a workable solution and that’s what matters.
