Hi!
How can I access the “turtle normals” on L-Systems?

for example - I've got simple Lsystem with 1 generation:
F+F^F+F
and I've got a custom digital asset, which shows only 3 lines - red x , green y and blue z, and I want to copy this digital asset to these points, so, that these lines will point directions of the “turtle” when he arrived to this point.

how can I get these normals?
