I am asking what is the best or recommended way how to "remember" an element in civil model?
To describe situation better: There can be e.g. alignment, represented by complex geometry. When there are e.g. 4 arcs, I need to remember (and later to identify again) e.g. 2nd arc, even when the geometry changed (so now it can be 1st or 3rd, or maybe it does not exist).
I am thinking about several options (ideas only, not tested yet whether can be implemented using C++ or NET API):
In bigger context, it should work as a weak persistent reference, so I can store this information and return back to this element (iterate model content), without to attach extra data, to use MicroStation DependencyAPI etc.
