AC21 - handrail editing

[alemanda]

I need to extend the panel over the last post.
How to do it?

How to edit the fixing points of panels? is it possible to move them freely to adapt to supporting structure?

How to stretch the landing structure in order to match it with the rest of the flight structure? Aren't there hotspot to do it? It would be very useful.
