Hey guys.

Maybe someone has a solution for next problem:
I want to allow a user to receive bridge length by entering each span lengths separately.
For example first of all I have variable N (span numbers) that tells me how many times I need to enter span length.
I that possible?

Simplest way:



With a more graphical approach, you can try with the modeller region.

Wow, thats works just well. Thanks

click in front to add upstream
click in back to add downstream
click in front demonstrated only.
So, you don't add separately, you select in group
or individually at will
