Steve thank you for your help. It is a lot to me.
I thought I will make this little diagram as it is probably unclear what I don’t know. I have attached the sketchup file as well.

Ah, yes, I see what you mean. Fredo6’s round corner wants to go between adjacent real faces, it does not understand the idea of the asymmetrical half-chamfer as if the other rail was still there. Here’s one way that you could handle this (there might be better ones but this will at least work). It may be confusing - If you can’t follow let me know and I’ll make a gif animation later when I have more time.
Fredo’s new round corner tool has a lot more options, including assymetrical as far as I remember?
Here’s an animation of what I wrote earlier.

Great animation!
This is great also! Thank you TIG.
This is really good tool.
Great video. Have you tried that tool? I have installed it but I don’t get the interface ![]()
