C# Help: Interactively manipulate datatrees

Well friends,

This C# only-no components WIP thing belongs to a collection of 7 definitions that create a vast variety of tensile membrane structures (I'll post them all when ready in the examples category).

My big issue is: how to interactively manipulate data : in this occasion shown read once a datatree, create a copy and then "scroll" (via a slider) through the main dimension branches and choose some to delete  (and/or modify data etc).

Any help/ideas could be greatly appreciated

best, Peter

BTW: given the opportunity (and irrelevant to the "interactive" issue) here's a strange thing:

DataTree "TriData" used in the problematic red C# is a mixed data type thing (declared as System.Object). Holds a variety of data (and some new will be added soon):

It's created in the C# (named Triangulator) just below the red C# script in question:

The odd thing is: when accessing the Polyline the cast type (Polyline) it doesn't work and a cast type of (Curve) is required instead:

Why?

Hmm ...

appears that the interactive bit is not considered something important (it should : it's the Holy Grail of engineering).

Here's how to do it using Anemone
