Help/assistance - Creating branches facade in rhino grasshopper

the pattern you show is repetitive.
guess you want it non-repetitive.
To generate trees you can implement an L-System

start implement it with curves. to see the concept.
then with (“black”) surfaces - for easier joining / union-ing.

maybe also search this forum more carefully:

EDIT - sorry the link above is not a big catch - it uses a given curve…
but maybe this is a nicer starting point:

start with some work, tell use where you stuck and post it.
