Spliting each rebar exceeding 12m length in a rebar set

Ok…I’m trying to manage on my own and fortunately I came across this post that suits me perfectly
[Rebar Question - #7 by MicCar]

by following the attached script and selecting my rebar set using the node Properties.Rebar.CenterlineCurves under Structural Design package I did not have the whole bar in my set displayed on dynamo (just the first one) …then when using the node Split curve with overlap (that I dont find it under Structural design package…I had to use the one under BIM4Struc package)…I got internal error telling me: removal of the reference of a non-pointer element!!?

How can I solve this issue and which nodes should I use to get polycurves of the whole of my rebar set using Structural design package??

Thanks.
