hello

I am trying to create a bisector line in a 3d space, centered at the intersection of 4 non linear lines. this bisector should be such that both angles are bi sected by the same line. To achieve this i attempted the following grasshopper code. In my code I constructed 2 vectors, working in pairs of 2 lines. I then tried to combine these 2 vectors and get a resultant vector which bisects perfecly but it seems mathematics dont work that way. my “true bisector” is not a bisector.

I would appreciate any help.

perhaps my approach is completely wrong, maybe i need to figure something out that is completely different. Im open to that too
